MRS JUSTICE CHEEMA-GRUBB DBE:
Introduction
The Law
"The test is the standard of the ordinary skilled man exercising and professing to have that special skill. A man need not possess the highest expert still: it is well established law that it is sufficient if he exercises the ordinary skill of an ordinary competent man exercising that particular skill.
I myself would prefer to put it this way, that he is not guilty of negligence if he has acted in accordance with the practise accepted as proper by a reasonable body of medical men skilled in that particular art…putting it the other way round, a man is not negligent, if he is acting in accordance with such a practise, merely because there is a body of opinion who would take a contrary view."
"The use of these adjectives – responsible, reasonable and acceptable – all show that the court has to be satisfied that the exponents of the body of opinion relied upon can demonstrate such opinion as a logical basis. In particular in cases involving, as they so often do, the weighing of risks against benefits, the Judge before accepting a body of opinion as being responsible, reasonable or acceptable, will need to be satisfied that, informing their views, the experts have directed their minds to the question of comparative risks and benefits and reached a defensible conclusion on that latter prose."
He continued (page 243):
"In the vast majority of cases the fact that distinguished experts in the field are of particular opinion will demonstrate the reasonableness of that opinion. In particular, where there are questions of assessment of the relative risks and the benefits of adopting particular medical practise, a reasonable view necessarily pre-supposes that the relative risks and benefits have been weighed by the experts in forming their opinions. But if, in a rare case, it can be demonstrated that the professional opinion is not capable of withstanding logical analysis, the Judge is entitled to hold the body of opinion is not reasonable or responsible. I emphasise that in my view it would very seldom be right for a judge to reach the conclusion that views genuinely held by a competent medical expert are unreasonable……..It is only where a judge can be satisfied that the body of expert opinion cannot be logically supported at all that such opinion will not provide the benchmark by which the Defendant's conduct falls to be assessed."

The Issues
a. Failed to monitor the foetal heart every five minutes in the second stage of labour. This was contrary to the Defendant's own Guidelines of April 2003 and led to a three minute delay.
b. Failed to take the foetal heart rate prior to the (artificial) rupture of the membranes.
c. In so far as the Claimant's heart rate was pathologically low at 1457 failed to summon immediate medical assistance at or about 1500 giving rise to seven minutes delay.
d. Alternatively in so far as the Claimant's heart rate was not pathologically low at 1457 failed to summon immediate medical assistance at or about 1503 giving rise to four minutes delay.
e. Delayed by involving Sister Lilley before summoning medical assistance. The length of delay was short but unknown.
f. Doctor Deshmukh failed to initiate a delivery by caesarean section within three minutes of her arrival. Leading to two minutes delay.
g. But for breach of duty a time frame of 6-9 minutes would have been saved and the Claimant would have been delivered by 1520 or 1523 rather than the actual time of delivery: 1529.
h. In respect of causation the Claimant alleges that had the 6-9 minutes negligent delay been saved he would have sustained a lesser degree of disability.

Plan crash LSCS decision made at 1513 hours. Mr Odukoya consultant on call informed of the plan agreed Explained to FS that we need to take her to theatre for LSCS quickly obtained verbal consent from FS for LSCS there was no time for a written consent. Signed and printed D Deshmukh. [The notes continue…..] FS had more bleeding PV in theatre before LSCS. FH was heard in theatre with sonic aid Bradycardia was getting worse |
|
1805 | Saw FS and her mother post operatively. Apologised for not having informed in details before LSCS due to time constraints. Explained placenta abruption after membrane rupture explained the reason for immediate LSCS explained that placenta had separated and there were clots inside the uterus and nitro placental clots. FS is drowsy and therefore I will speak to FS later. |
5/6/05 2145 |
[Dr Deshmukh made a further entry.] Explained to FS today the situation which led to crash LSCS. Answered the questions asked by FS tried to explain as much as possible explained that rarely placenta abruption can occur after membrane rupture… |

Claimant's Factual Witnesses
"….entered the room no more than 3 or 4 times in all, for no more than a minute each. Midwife Voulgaris stood at the door and spoke to us; she did not check or sign any of my notes and made no observations. The only time she entered the room was to bring refreshments for my mother and partner. All of the notes were written by Student Midwife Lusby-Spedding".
"During this time I was in excruciating pain and my tummy was rock hard. The student midwife commented on this a few times but it does not appear in the notes. I do not know what caused this or whether it is relevant to DS's condition. I just know that it happened and it wasn't right. I am concerned whether this was an indication that the baby needed delivering at this time but they didn't act upon it but I know the experts in the case and the Court will consider this."
"Not once during my whole labour had I had the urge to push or had I been pushing. I was under a sheet from when I was examined up until 15.00 when the student midwife asked me to push. At first I said no but she kept trying to persuade me to but then I gave in and pushed as hard as I possibly could. This was when the "balloon" was delivered. My mother told me it was like a white balloon filled with black ink. I did not actually see this. The student midwife asked Pip [DS's father] to press the buzzer, she looked panicked and confused, as did my mother. On entry to the room, the trained midwife said "What's that?" The student replied "I don't know." Then the trained midwife said "Has her waters broke" to which the student midwife replied "I don't know". I clearly heard this said.
I was told by my mother that a dark sac of bulging membranes was visible at the vulva. I can remember this clearly. I understand midwife Voulgaris broke the sac with a hooked instrument of some sort and there was red blood everywhere, although I never actually saw the sack. It was clear from the mid-wives' reactions that something wasn't right.
Neither the student midwife, nor the trained midwife, tried to measure the baby's heart rate before they broke the sack. After they broke it they didn't try to measure the heart rate but when they saw all the blood everywhere they asked Pip to press the emergency buzzer. A third midwife came into the room and tried to measure the foetal heart rate, but after putting gel on and trying a few times she was not able to obtain the foetal heart rate and she put more gel on. The emergency buzzer was pressed again.
There was then a series of activity. There was an air of panic. The doctor arrived and carried out a vaginal examination. When she did this more blood came out and then she called the crash emergency caesarean, there were buzzers going off."
i. "What happened during the intra-partem period from her admittance to delivery?
ii. What time the abruption occurred?
iii. What happened in theatre i.e. pre-op and enter operative period?
iv. How was the baby resuscitated and what were the measures taken?"
"FS herself remembers that at one point her contractions were getting stronger and that she was told the abdomen was rigid. She then asked if the abruption happened at that stage. On reviewing the notes at that stage the foetal heart rate was about 118 beats per minute and FS on direct questioning said she had no pain in between the contractions. These two points would make a diagnosis of abruption at that stage very unlikely."
"With regards to her question of when the abruption happened. Firstly I told FS and her mother that abruption is not something that is predictable. There are no measures or investigation which can tell us when an abruption could happen. On reviewing the notes I have assumed that abruption had happened at the time when the foetal heart was running low and according to FS at the same time she also experienced increasing abdominal pain which was at around 15.00 hours."
"We had wanted to know what had happened minute by minute; they flicked through the note nonchalantly. FS had wanted to draw a line in the sand, wanted to know what had happened so that they could come to terms with it."
The Midwifery Evidence

1630: FS's partner, mum and partner's mum informed verbally of the baby's condition."
"I returned to the room, presumably after a short break because I was present at 1452 as I countersigned Andrea's entry in the notes. Andrea would have been in the room with FS during the period from 1452 to 1500. I noted there was a bulging bag of membranes evident at the vulva. The bag of fore waters spontaneously ruptured. I note it is alleged that the membranes were artificially ruptured with a "hooked" instrument. This instrument described is presumably an amnio hook which we use for rupturing membranes. Andrea has recorded "SROM" in the notes indicating that this was a spontaneous rupture…..I also recorded that the liquor was clear confirming there was no blood in the liquor nor was there any meconium. There was a small mucousy show which may have contained some blood stain. I osculated (sic.) the foetal heart with a sonic aid and noted it had dropped to 60 bpm. I then rechecked the findings using a Pinnard and noted the foetal heart was 56-60 bpm. I pulled the emergency buzzer requesting assistance from the Labour Ward co-ordinator Sister Carol Lilley came into the room. In between contractions we changed FS's position to a more sitting up position (as she had slipped down the bed) so that I could perform a vaginal examination and to see if the foetal heartbeat improved with a change in maternal position. During this period I was trying to verbally reassure FS who was very frightened. At 1505 I performed a vaginal examination to ascertain what was happening. It was possible that the bradycardia had been caused by cord prolapse or cord compression and I wanted to exclude this or to intervene if that had been the cause. I confirmed that FS was fully dilated and that the baby was in the ROP position. There was no vaginal blood loss at this point. I applied a foetal scalp electrode in order to obtain more accurate monitoring of the foetal heart. I also double checked the maternal pulse to make sure that we were picking up the foetal heart not the mother's pulse. At 1507 Dr Deshmukh the Obstetric Registrar was bleeped probably by Carol. Dr Deshmukh must have been close by as she was in the room within 1 minute at 1508. I provided a history and she performed her own vaginal examination to assess progress and determine the best mode of delivery. During the vaginal examination between 1508 and 1509 there was a sudden blood loss vaginally. This was the first time that there had been any vaginal blood loss during the labour. During this period I was attempting to osculate (sic.) the foetal heart but it was difficult while the vaginal examination was being conducted. However the foetal heart remained low at 69 bpm".
"I would have been in and out of the room but this would have been frequent. I was supervising Andrea Herron who was still a student midwife at the time. This meant that Andrea was practising on my registration so it would have been very important to me that I checked what Andrea was doing. If I had been out of the room when I came back in I would have checked the entries Andrea made in the records and I have countersigned the records to confirm that Andrea's entries were checked. In addition, I would definitely have been in the room when Andrea carried out the vaginal examination."
"There was no indication of any risk in this labour. I expected her to progress to the second stage and a normal vaginal delivery. I would have expected this four hours after she was 8cms dilated. I decided not to do a vaginal examination because there were all the normal signs of a normal labour and no contra indications suggesting a need to do a vaginal examination. There are always reasons not to do a vaginal examination for example the risk of sepsis, risk of infection to mother and baby and the distress caused to the mother. It was common to defer the vaginal examination at that time in my practice."
"…we had a distressed lady, had to change her position. I called for assistance immediately after I had listened to the FHR for one minute. I called the co-ordinator to report."
"I had to make the lady comfortable, with clear liquor had to change the sheet, listen to the foetal heart rate, to make a risk assessment, we were trying to exclude cord prolapse which would escalate to immediate emergency, explain to those present what was going on, reassure FS and inform Sister Lilley. I established that this was an emergency situation rather than one of the typical decelerations, when I re-checked with the Pinnard."
"There was no period when we were doing nothing between 1500-1507, or doing inessential things or not doing tasks we needed to do."
"there are a number of findings and symptoms of the second stage and the most common is an urge to push… other presumptive signs include expulsive contractions, and a blood stained mucus show both of which were not present… in essence Ms FS was beginning to show signs of transition from 14:00 and continuing midwifery support and observation of Ms FS was appropriate until the membranes were visible at the introitus at 15:00 the decision to await further presumptive signs or sight of the vertex was a conscious and reasonable plan".
"the deceleration of the foetal heart at the point of SROM does not warrant immediate medical aid as the presence of a deceleration of the foetal heart rate as the membrane rupture once the second stage has commenced is not unusual. Therefore, to call for aid at this point was cautious. It was mandatory to perform a vaginal examination to confirm the full dilatation and absence of a cord prolapse. They also needed to establish that what they were hearing was the foetal heart rate not so applying an FSE to establish that the foetal heart rate was foetal and not maternal was reasonable".
HG on the other hand whilst accepting that such actions as maternal repositioning and a vaginal examination to exclude cord prolapse as a cause were reasonable, stated categorically,
"when there has been a persistent bradycardic FHR for over three minutes this is an obstetric emergency situation which should result in the use of emergency call bell and a responder requesting emergency medical obstetric attendance and a CTG machine, if not already available in the room".
"I believe the timings were reasonable and as an example of what might be happening:
15:00-15:03 SORN and SHR drop noted moved Ms FS into a different position, recheck foetal heart rate, called for assistance and continued to try and listen to the SHR which would be difficult given that the foetal head was low in the pelvis.
15:03-15:06 Ms FS into a position to a vaginal examination, do vaginal examination, attach SSE and establish that SH was remained at 70bpm by 15:06.
SR Lily leaves room and calls doctor at 15:07.
15:08 doctor attended.
In my experience this was a reasonable time interval in light of the fact that at the start of the bradycardia the events could have been within the normal range of a normal labour. Only as time progressed it was established that the foetal heart rate was remaining below 100bpm did it become clear that there was no obvious reason for a bradycardia (such as a cord prolapse) and once established the FHR had shown no recovery".
HG however made the following observations at the joint meeting,
"The notes do not include detailed information as when and how an FHR at 60bpm was first determined by student midwife Spedding before midwife Voulgaris attended at 1500, why she recorded a rate and not a rate range… there are therefore several differing timings of when emergency senior medical obstetric attendance should have been sought. One, by 15:03 at the latest if a foetal bradycardia at three minutes was first identified at 15:00 (and if no FHR had been checked since 14:52 as a foetal bradycardia from then on could not be excluded as a possibility, and was therefore even more acute situation). Two, 15:00 if a foetal bradycardia 60bpm was first checked at 14:57 (as a result of a regular five minute osculation (sic.) Check which student midwives Spedding states she was carrying out from 14:06). Three, 15:02 (if the FHR of 60bpm noted at 15:00 was as the result of counting the FHR for a minute as recommended practice starting from 14:59)".
"Prospectively you cannot know if it is going to recover or whether this is a baby who is not recovering and so you have to assess change in heart rate very carefully to decide whether this is a baby who is going to have difficulty. Midwives work at different rates but everything described can be achieved by a competent midwife in 3 mins and I would expect any competent midwife to react to a foetal bradycardia as I have discussed within a 3 min period and if FHR remains low after 3 mins it is not a situation she can prospectively assume will resolve and she needs obstetric assistance."
Plainly, the reaction time she suggested required the midwives to be wary and assume that, although/because they hadn't listened to the FHR consistently for 3 minutes, it was a continuous period of deceleration and act upon the algorithm to expedite delivery by calling a doctor.
"You have to detach one of the monitors and put the FSE into the CTG…… The midwife will keep her fingers in the vagina while someone else attaches the end of the FSE to the monitor, so they can fiddle around with it to get good contact."
Of course at the time the FSE was being attached there were three midwives present in the room.
"To me this means the midwife asked FS to give small pushes in order to see if she can see the baby's head." Later she confirmed, "This is not an instruction for an active 2nd stage. If expulsive pushes had started then I would expect to see '2nd stage, pushing commenced' or similar note 'we are in 2nd stage'…it is common practice to write in the point at which 2nd stage started. A typical note might say 'pushing well…head seen…'"
She repeated her view that it was not necessary to assume FS was in the 2nd stage and so to increase monitoring of the foetal heart, if a vaginal examination was going to be delayed until 1515 in anticipation of the 2nd stage.
"A baby's heartbeat going down is a very, very normal thing to happen and it is very rare for it not to recover so the midwives were reasonably expecting it to recover."
Findings as to Midwifery
a. FS had an unexceptional pregnancy and labour until 1500 on 4th June 2005.
b. From 0818 she was cared for by SMW who was supervised by MWV. MWV was not present in the labour room throughout but was there most of the time and was actively engaged in FS's care although SMW was being given the opportunity to take the lead, which was reasonable and consistent with her nearly qualified status.
c. MWV was present during the vaginal examination at 1010 although it was carried out by SMW. I am satisfied that this supervising midwife would not have let a trainee carry out such an important step alone.
d. MWV counter-signed the entries in the labour notes either at the time they were made by SMW or in blocks when she returned to the labour room after an absence of up to ½ hour.
e. FS was not in constant severe pain at any stage, she was generally coping well with the contractions and using Entonox anaesthetic when necessary. Although rupture of the membranes had been assumed from liquid draining from the vagina at 1150hrs the baby's head was not seen at the entrance to the vulva. At that stage the position of the foetus was not known and a vaginal examination was expected, according to the recommended 4 hourly interval practice. I am satisfied that no vaginal examination was done at 1410, or at all before 1500, because it was reasonably assumed by the mid-wives that FS was close to entering the 2nd stage of labour and her child would soon be born. A decision to defer the vaginal examination for an hour, in consultation with the Labour Ward Co-ordinator, was reasonable in all the circumstances and not a breach of duty.
f. There was no occasion (before 1500) on which FS's abdomen was very hard or when SMW expressed concern about it. This has probably been mis-remembered by FS and ES.
g. FHR monitoring was increased from 1138hrs although the rate of monitoring was not constantly maintained. This being classified as a low risk labour continual monitoring was not indicated. I am not satisfied that the reduction in intervals was instituted at any time because the mid-wives believed that FS had entered either part of the 2nd stage of labour. I have regard to a Mid Cheshire Hospitals NHS Foundation Trust's document defining the different stages of labour.
"The First Stage
The first stage is where the cervix opens from 4cm to 10cm with regular contractions. These become stronger, longer and more frequent….The length of the first stage of labour varies between each woman. On average, labour will last about 8 hours for women who are having their first baby and is unlikely to last over 18 hours…….
The Transitional Stage of Labour
The transitional stage is described as the most painful part of labour, as your body is changing from the cervix opening to the body getting ready for the pushing stage. Women often experience the transitional stage around 7-10xm dilated. …….
The Second Stage of Labour
The second stage begins when the cervix is fully dilated and ends with the birth of the baby. The second stage usually takes place within three hours for women having their first babies and within two hours if you have had a baby before. The second stage can be divided into two parts:
Passive stage: fully dilated but no urges to push
Active second stage: when one or more of the following exist:
Expulsive contractions (making you want to push) with the finding of full dilatation of the cervix
Active maternal effort, following confirmation of full dilatation of the cervix in the absence of expulsive contractions
External signs of full dilatation."
h. If FS had reached the 2nd stage of labour shorter intervals between monitoring the FHR were required as described in the Trust's 'Foetal Heart Monitoring in Labour Guideline' issued in April 2003. In that Guideline a clinical algorithm demonstrates how frequently intermittent auscultation is to be used:
".. .where intermittent auscultation is used this should occur after a contraction, for a minimum of 60 seconds, and at least:
Every 15 minutes in the first stage
Every 5 minutes in the second stage."
i. Although the intervals between monitoring reduced (inconsistently) from 1138 both midwives gave evidence consistent with the detailed contemporaneous records, that FS was not in the 2nd stage of labour but, in due course, believed by them to be in transition between the first and second stages. On balance and with some qualms, I accept this evidence, which is consistent with a lack of a note indicating the arrival of the 2nd stage of labour and reject the assumption relied upon by DS that an increase in monitoring could only have been instituted because FS was believed to be in the 2nd stage of labour. In the circumstances I conclude that monitoring at least every 5 minutes was not mandatory before 1500.
j. In the initial Particulars of Claim it was alleged that FS's contractions ceased altogether at 1330 consistent with her statement. However, this allegation has been withdrawn although it remained part of FS's statement which she confirmed at trial. The records, including the partogram record, show that the contractions continued to be felt e.g. at 1335, 1345, 1406. While it is plainly possible that auscultation of the foetal heart at 1457 may have indicated possible foetal bradycardia at that time I do not accept the Claimant's case that failure to monitor his heart beat at 1457 was in breach of the midwives' duty. The increase in frequency of monitoring of the foetal heart-beat was, I accept, due to enthusiasm by the student midwife rather than because it was recognised the FS had begun the 2nd stage of her labour. The reduction in frequency of contractions recorded in the notes between 1230 and 1429 was not a demonstration that FS was in her 2nd stage.
k. I am not satisfied that the midwives ruptured the amniotic sac of membranes with an instrument. On the contrary rupture was spontaneous and I am satisfied that the Claimant's grandmother probably mistook the Foetal Scalp Electrode for a hooked tool because this was inserted within a few minutes of the spontaneous rupture of the sac of membranes and at a time of distress and concern in the labour room. I am also not satisfied that rupture of the membranes was accompanied with any significant bleeding, as described by ES.
l. While it is agreed that a FHR of 60bpm was recorded at 1500 I am not satisfied that it is possible to say, even on the balance of probabilities, that DS' heart beat had been at that rate from shortly after 1452. I find that it was reasonable for the midwives not to treat the 1500 reading as indicative of severe foetal bradycardia requiring immediate medical assistance at that time.
m. However, at 1500 the nature of FS' labour changed. A deceleration occurred in the FHR due to placental abruption which had taken place upon rupture of the membranes or shortly before. The question is, when should the midwives have realised that medical aid was essential or rather, has the Claimant proved that failing to call for an obstetrician from 1500 to 1507 was a negligent failure to perform their duty?
n. I am satisfied that continuous monitoring of the FHR from when the deceleration was first detected at 1500 should have been instituted and any reasonable body of midwives would have made this a priority because if it demonstrated that the FHR was low for a continuous period of 3 minutes the Trust's guidance mandates the calling of medical help and the expedition of delivery: in short, a emergency situation. Although the midwives did not fail to react to the deceleration: MWV took over primary care for FS, made her comfortable after rupture of the membranes and began to try to discover the reason for the deceleration and whether it was temporary, they failed to institute continuous monitoring. None of the midwives provided any coherent explanation for this except by reference to experience showing how frequently sudden decelerations in FHR recover.
o. This was a reasonable approach at 1500 but I find that after four further minutes it became evidence of unjustified and dangerous complacency. The deceleration should plainly not have been treated as temporary thereafter. When MWV established that the deceleration had not recovered by 1504 she called the Labour Ward Coordinator and they carried out a vaginal examination including the attaching of a Foetal Scalp Electrode to begin continuous monitoring. This caused a further delay of 3 minutes before Dr Deshmukh was called. While these were reasonable steps which a reasonable body of midwives could have chosen to carry out in respect of a previously normal labour I do not accept that it was reasonable to carry them out after 1504 when there had been a potential period of hypoxia from at least 1500 already and, as far as the midwives knew, from sometime before then, without also calling for medical assistance at the same time. Although it is inappropriate to attempt to attribute particular time intervals to the actions carried out I am quite satisfied that between 1500 and 1507 there was a negligent delay of 3 minutes in calling the obstetrician.
p. It follows that the calling of the Labour Ward Coordinator, whilst entirely acceptable practice, is a step which should not have delayed seeking medical assistance once it had to be presumed that the FHR had been at a very low level between 1500 and 1504. I accept the Claimant's case that considering matters prospectively, at the time, if the midwives were to carry out a vaginal examination after 1504 that should have been alongside taking the action of calling for an obstetrician. I accept that there was no evidence to confirm placental abruption as the reason for the reduced FHR until blood was seen during the vaginal examination carried out by Dr Deshmukh (recorded as occurring at 1508-09) however, this does not absolve the midwives, and it was their duty to seek medical assistance after the FHR had not recovered by 1504.
q. In short, given that low risk pregnancies are midwife led and decelerations in FHR occur frequently towards the end of labour whereupon spontaneous recovery is usual, it was not mandatory for the midwives to call for an obstetrician before 1504. Until then the midwives caring for FS could have reasonably instituted continuous monitoring, determined whether FS was fully dilated, tried to make adjustments to enable the FHR to recover and seek to determine for themselves what the cause of the deceleration was and whether it could be counteracted but by 1504 a FHR deceleration of at least 4 minutes duration had to be assumed (in the absence of continuous monitoring) and it was mandatory to obtain obstetric assistance. The delay thereafter was in negligent breach of duty.
The Obstetrics Evidence
"When I arrived in the room I took a history from the midwife and ascertained that FS had had spontaneous rupture of the membranes at 1500 and there was a bradycardia. Due to difficulties in locating the foetal heart, the midwives had applied a foetal scalp electrode. Sometimes, when the mother commences pushing it can cause a transient bradycardia and I needed to rule this out. I also considered the possibility of cord prolapse. I performed an abdominal examination which would have taken about 30-60 seconds. I noted that the uterus was contracting and was possibly tender. The foetus was in the cephalic position and 1/5th was palpable i.e. the foetal head was in the pelvis but still palpable abdominally. I reviewed the CTG trace and noted a foetal bradycardia of 70-80 bpm.
I then performed a vaginal examination. This took approximately 1-2 minutes. I immediately saw blood stained liquor. The cervix was fully dilated and the foetal head was at station 0 i.e. at the level of the Ischial spines. The foetal head was in the ROP Right Occipito Posterior Position. I ruled out a cord prolapse and considered a possibility of placental abruption. Sometimes, if there is a huge fluid loss caused by rupture of the membranes (i.e. a sudden gush of fluids) the placenta is pulled away from the uterine wall and starts to separate.
Although I have not recorded this in my retrospective note, I remember debating in my mind whether to do a trial of forceps. The foetal heart was palpable and low down in the pelvis but the rotation was not complete (the baby was in the ROP position) so it wouldn't have been the easiest of forceps delivery. However, as I withdrew my fingers I noted further fresh vaginal bleeding. When I saw the fresh blood, placenta abruption was the likely diagnosis so I decided not to waste any time trying a forceps delivery and at 151`3 I called a crash section. Overall it took me 5 minutes to take a history, perform an abdominal and vaginal examination, assess the situation and make the decision to perform the crash caesarean section".
"Cleaned, draped and catheterised. Transverse lower abdominal incision to open lower abdomen. Lower segment C- shaped incision to uterus. Baby delivered as cephalic, male, floppy, live. Placenta partially separated, with large retro-placental clot, delivered by CCT. Uterine cavity checked – blood clots removed……Estimated blood loss 1500 ml approx... including the clots found in the uterine cavity…Baby was deflexed, ROP at spines, head had to be pushed from below. Placenta was partially separated with bit retro- placental blood clot, more than ?, was already detached….diagnosis: massive placental abruption? Associated placental haemorrhage from placental site… "
Her statement continues by recording that the operation was conducted very quickly
"Knife to skin occurred at around 1528. The foetal head was low in the pelvis and I had to ask one of the midwives to assist in pushing the foetal head back up so I could deliver…..The baby was delivered in poor condition, was very pale and floppy…"
"I would have to be satisfied that what I was getting were findings upon which I could make a decision".
"I was in the room at 1508 and baby was out 21 minutes later. We made our best efforts…..If the time was taken with positioning the lady, opening the pack, waiting for a contraction to pass then that time was taken (i.e. it was inevitable). I decided not to attempt forceps delivery, she was fully dilated and pushing very well. I wanted to get the baby out as soon as possible."
"..there was such a call, I was still in my gloved hands when we had a conversation with the mother and then went for the crash call. I had decided that vaginal delivery was not possible so I could not do a trial of forceps."
"..we do not normally do that, make a crash call in the second stage of labour, when I am anticipating a vaginal delivery. I disagree that as soon as I entered the room I should have made a crash call because of the scale of the bradycardia, I knew (of the) bradycardia, I knew it had lasted for 8 minutes at least and may have been 16 minutes…a crash call means alerting everyone and them all coming and by that time I may have done a ventouse delivery."
Mr Elgot persisted with his point that her reasoning should have been that if she did a crash call and then it turned out a caesarean was not necessary it would have been wiser even if the call out was wasted. Dr Deshmukh said a crash call could not be taken lightly
"in hindsight the outcome was not good but at the stage I entered the room we do not do a crash call. At the time that I entered the room we were still hoping that a vaginal delivery was possible although it was clear that the baby had to be delivered expeditiously."
"The Claimant's heart beat was monitored at 1452. Should the Claimant's heartbeat have been monitored at 1457 or is that a matter for the midwifery experts. Please give reasons for your answers."
The experts confirmed again that the rate of monitoring depended on which stage of labour FS had reached. GJ however expressed his opinion that "on the balance of probability the cervix was fully dilated, then auscultating every 5 minutes would mean that the auscultation after 1452 should be 1457".
Question 17 asked
"What was the likely sequence of events between the rupture of the membranes and the foetal bradycardia at 1500 hours?"
GJ was uncertain as to the meaning of the question. He said "spontaneous rupture of the membranes and the onset of the foetal bradycardia are not synchronous nor are they directly related although rapid release of liquor can increase the degree of placental separation. Artificial rupture of the membranes would often be a clinical response to foetal bradycardia". DT answered question 17 in this way, "the membranes ruptured, releasing tension in the uterus which led to acute placental separation and a sudden foetal bradycardia".
"Using the delivery suite clock timings, how long did it take Dr Deshmukh to assess the patient and make a decision to proceed to an emergency caesarean section? Having regard to the Bolam test was this a reasonable or unreasonable time interval for this assessment?"
The experts agreed that Dr Deshmukh was present at 1508 and made the decision for caesarean section at 1513. GJ continued, "given the combination of a foetal bradycardia and a presumed placental abruption it should have taken no longer than 3 minutes. To take longer was unreasonable. In the presence of a foetal bradycardia time is of the essence and small differences in time can be crucial to the outcome for the baby." DT responded to the question in this way "this was reasonable as she had to assess the situation on arrival and then perform a vaginal examination to see if delivery would be vaginal or by caesarean section. To take 2-3 minutes to decide to deliver and then 2-3 minutes to perform a vaginal examination to decide on mode of delivery so 5 minutes overall was reasonable." GJ went on to reply in respect of a subsequent question that "by 1508 there had been a foetal bradycardia for at least 8 minutes. Within 1 minute of arrival at 1508 there was vaginal bleeding. All that was needed for a decision was a decision as to the mode of delivery, the vaginal or abdominal thus 3 minutes was the maximum time required (to request Caesarean section after her arrival)".
Findings as to Obstetrics
a. Although detection of a bradycardic heart rate earlier than at 1500 would have meant, in all likelihood, that the actions carried out at 1500 would have occurred earlier, resulting in delivery and resuscitation earlier, I am not satisfied on the balance of probabilities that foetal heart monitoring at 1457 would have revealed a bradycardic heart rate. I accept the evidence of DT that is much more likely that had a FHR monitoring taken place at 1457 the rate would have been normal. Decelerations can occur very quickly and this one was due to abruption rather a long-term cause. DS' brain damage had caused less serious disabilities than might be expected after a long period of acute hypoxia and the evidence tends to suggest a shorter period would explain that. These are some of the reasons why I have concluded that monitoring at 1457 would probably not have caused alarm.
b. I accept Dr Deshmukh's evidence that she was not aware she was being called specifically because of a pathologically low FHR but she was aware of that fact as soon as she entered the labour room.
c. Dr Deshmukh arrived expeditiously. She was suitably qualified and experienced to be the on-call obstetrician. The history taking and speaking to FS was appropriate and swift.
d. Dr Deshmukh decided to do her own vaginal examination and it was reasonable for her to do so. Dr Deshmukh was able to start her vaginal examination within a minute of arrival.
e. The sudden loss of blood per vagina at 1508-1509 during the vaginal examination alerted all the Trust's staff present that a placental abruption was likely to be the cause of the low FHR.
f. Thereafter Dr Deshmukh's task was to decide whether DS could be delivered vaginally with instruments, which would have been a speedier delivery, or whether an emergency caesarean section was the only option. She took between 1509 and 1513 to make that decision. She made a crash call at 1513. I am satisfied that this was a reasonable period of time for an obstetrician to make the decision, although other obstetric colleagues may have made the decision more quickly, the four minutes taken was within the range of reasonable periods. In other words I do not find that it was mandatory for her to have decided to do a caesarean section within 3 minutes of entering the labour room. I found the evidence of GJ to be a counsel of perfection and influenced, to a degree, with the benefit of hindsight.
g. The Claimant has not persuaded me on the balance of probabilities that his obstetrician was negligent in her treatment of FS. The delivery of DS at 1529, within 21 minutes of her arrival in the labour room demonstrates her efficiency and the urgency with which she worked. I am satisfied that this was her attitude throughout her dealings with FS, not just after she'd made the decision for a crash call.
The Remaining Experts
Neuro-radiologists
Neonatal Experts
"What was the nature and duration of the brain insult suffered by the Claimant following the placental abruption?"
The experts agreed that the acute profound hypoxic ischaemia probably lasted from around 1455-1500 until resuscitation was achieved. Resuscitation in these circumstances is acknowledged when a heart rate of more than 100bpm was obtained. There was agreement that a previously healthy foetus could withstand 10 minutes of acute profound hypoxic ischaemia without sustaining irreversible brain damage, although they were both aware in clinical practice both shorter and longer periods may be seen.
Paediatric Neurologists
"Having regard to the neuro-radiologists Joint Statement, on the balance of probabilities what was the cause and mechanism of the Claimant's brain damage?"
The experts answer was:
"We note that the neuro-radiologists conclude that the pattern of brain injury seen in DS's brain is that of an 'acute profound' hypoxic ischaemic insult. They point out, and we agree, that there is a mismatch between the extent of white matter loss (which is not present) and DS's microcephaly. We agree that DS's radiologically demonstrated pattern of brain damage is a consequence of an episode of acute and profound cerebral hypoxic ischaemia (APA). We agree that the clinical presentation of DS is unusual in terms of the pattern of his cerebral palsy and that it is much more usual to see a dystonic cerebral palsy with athetosis as a consequence of extrapyramidal motor function impairment. However we agree that bilateral spastic cerebral palsy can be seen."
Question 8 was
"What was the nature and duration of the brain insult suffered by the Claimant following the placental abruption?"
In response the experts agreed that DS was exposed to and sustained his brain damage as a consequence of a period of "acute profound" hypoxic ischaemia (APA). They continued,
"So far as the duration of this period is concerned, we consider that this probably lasted from around 14:57 to 15:00 (the time of onset as a continuing profound foetal bradycardia until resuscitation was achieved as marked by achieving a neonatal heart rate of more than 100 beats per minute between 10 and 15 minutes after birth. We agree that DS was born at 15:29… Hence the duration of the hypoxic episode was a maximum of 47 minutes (14:57 to 15:44) and a minimum of 39 minutes (15:00 to 15:39)."
"We agree that DS was in very poor condition at birth, effectively still born. He had no recorded heartbeat, was floppy, pale and not breathing. DS required full cardiopulmonary resuscitation with chest compressions, positive pressure ventilation and intravenous adrenaline. We agree that determining the duration of the resuscitation is best done by referring to the neonatal records, and Apgar. The paediatric team will almost certainly have assigned Apgar scores and made notes of events using the timer on the resuscitaire rather than referring to any clocks or watches. We agree that the Apgar score at 10 minutes recorded a heart rate of less than 100bpm, and by 15 minutes of age DS's heart rate was noted to be above 100bpm."
"1. An initial non damaging period of 10 minutes followed by a prolonged damaging period of 32 to 37 minutes;
2. A damaging period of closer to 15 minutes preceded by a prolonged non damaging period of 27 to 32 minutes;
3. Apportioning the total period of APA on the basis that 40% was non damaging and 60% was damaging, this is the model used when the conventional maximum period of APA of 25 minutes is the case."
LR preferred to adopt option 3 in this case, although he accepted there is an absence of published literature to support or refute his choice. He also pointed out the additional complication that DS's neurological disabilities are atypical because of the pattern of cerebral palsy and his microcephaly, but they are not at the most severe end of the possible spectrum and the abnormal radiology cannot offer precise or specific timings. Having made those observations, his answer to the question was that if option 3 was accepted that would lead to approximately 18 minutes of non-damaging hypoxia followed by a damaging period of 24-29 minutes. Thus the brain damage would have begun at 1515 and continued until 1539 or 1544.
MC preferred to use the conventional method because there is supportive experimental and clinical evidence that non-damaging APA is limited to a period of 10 minutes and the absence of published evidence that supports the apportion model relied on by LR. This analysis leads to an estimate of 10 minutes non-damaging hypoxia and 32-35 minutes of damaging hypoxia so the brain damage would have begun, at the earliest at 15:07, and continued until 15:39 or 15:44.
"In an acute asphyxia insult there is progressive neuroanatomical damage. It is hard to conceive therefore that saving six or nine minutes would have had no beneficial effect when it is clear that in APA the damage is progressive. Six to nine minutes is a significant proportion of the total asphyxia insult and would have been damaging, although how much less damaging is uncertain. Noting the sequence of neuroanatomical damage it is likely that the non-damaging period in respect to cognition is longer than 10 minutes and hence the damaging period less. In this case six to nine minutes would have been a greater proportion of the damaging APA and because of this have an even greater likelihood of reducing negative functional effects in respect to cognition. I consider that the intellectual impairment would therefore have been much less and that it is possible that it would not have been present at all. Hence using the estimates of IQ equivalent, given above, it is my opinion that DS would probably have functioned at IQ level 70 to 80."
"No, the diagnosis would have been the same but within it a shorter period of asphyxiation would have been associated with some changes in function."
"I think the description of his motor disorder would have stayed the same but the effect of it may well have been different."
"My clinical experience of many children exposed to APA is that there is a gradation of impairment…if only 5 minutes of APA insult then the individual would have disabilities but be largely mobile and largely cognitively intact by 10 minutes of APA insult a child would need a wheelchair for outdoor use and some degree of speech impairment and cognitive impairment. By 15 minutes of damaging hypoxia a child would be much more severely damaged…so I agree with the linear progression though it is not supported by research papers etc".
Findings on Causation
i) It is agreed that DS's motor functions would not be materially different.ii) Although there is understood to be a relationship between the duration of an acute profound hypoxic episode and the severity of brain injury caused, the relationship is not simple to define. The Claimant was apparently a healthy and robust foetus. He suffered a long period of hypoxia, at least 39 minutes (1500-1539) but more probably longer. Making an allowance of the generally accepted 10 minutes of non-harmful hypoxia (as described by the paediatric neurologists), he survived at least 29 minutes of injurious hypoxia but displays less profound injury than might be expected after that period of exposure. His neurological disabilities are atypical and not at the most severe end of the spectrum.
iii) While common sense suggests that a reduction of 6-9 minutes of exposure (as a proportion of the whole) would have made a difference to DS's cognitive abilities it is difficult to be certain, whether it would have been a material difference. This is especially so when DS's atypical radiology results are taken into account however, I have to apply a lower threshold of proof, namely the balance of probabilities.
iv) I am unable to decide on the evidence that AE is right when he says that had the 6-9 mins of alleged negligence been saved and DS been delivered at 1520 or 1523 DS would probably not have required more than five minutes of resuscitation. This evidence was based on his opinion that resuscitation is a process and progressive and although a healthy heart beat of 100bpm was not recorded as achieved by DS until 15 minutes post-delivery, he is likely to have recovered somewhat before that time. The difficulty with his analysis was, as he admitted in cross-examination, that he was making an assessment based on educated speculation rather than reliance on the resuscitation notes. He also disregards the evidence JR considers to be important; the fact that at 14.05 mins post-delivery DS was given a dose of adrenalin.
v) I accept JR's evidence, which was not contradicted by AE in this respect, that the training and algorithms of good practice relevant to neonatal resuscitation would not indicate adrenalin, which is a strong drug, unless necessary and it would be unlikely to be necessary if DS had been recovering already by 14.05 minutes post-delivery. The function of adrenalin is to stimulate the heart rate. It follows that I am not able to accept the AE's evidence that resuscitation time even with an earlier birth would have been much less than 8 minutes.
vi) If MC's attempt to use a mathematical formula to calculate a proportional improvement to DS's IQ were to be adopted, bearing in mind my finding that even after a birth 9 minutes earlier JR is right to predict 8 minutes or so of resuscitation, probably, at best an improvement in IQ from 50 (at present) to below 70 would result.
vii) In any event, AE, as C's neonatal expert, defers to the paediatric neurologists as to the difference in function that saving 6-9 minutes would have made. However, on all the evidence I have read and heard, I am persuaded that if birth had been as much as 9 minutes earlier, a substantial proportion of the total hypoxic insult would have been avoided and although I cannot calculate it exactly I am satisfied on the balance of probabilities that it would have made a material difference to DS's cognitive abilities so that although the care support he needed may have been the same his ability to manage himself, to make daily (not legal) decisions and the degree to which he would be able to join in his care would have been substantially improved.
viii) On the other hand, in all the circumstances the Claimant has not persuaded me that it is likely he would have suffered materially less injury had he been delivered 6 minutes before 1529 on 4th June 2005. DS was bound to suffer significant brain damage from the acute hypoxia following placental abruption until resuscitation and although a saving of 6 minutes before delivery and a consequential shorter period of necessary resuscitation may have made some proportionally minor difference to his cognitive functioning, it is impossible to say to what extent that saving of time would have improved his current condition.
Conclusion
