44 The information in the birth register was, as a matter of general practice, completed by the midwife present at the birth. There was no direct evidence as to the source of the information contained in the birth register entry for Wassif. Sister Orrock gave evidence that such entries were normally taken from the obstetric notes. Mr Clements said the information would be obtained from the obstetric notes rather than the paediatric notes but that, in his experience, midwives made the entry from their own observations of the operation and that a precise description of the caesarean section was not necessary for the birth register or the paediatricians. The source of the entries in the paediatric records was unclear though unlikely to have been the operation notes.
45 There was also evidence, which was not disputed, that many nurses use the expressions LSCS or LUSCS to describe any caesarean section irrespective of its nature. In these circumstances the available documentary evidence from PANCH cannot be regarded as conclusive as to the nature of the caesarean section performed on 31 October 1978.
46 It is thus necessary to have regard to other evidence in order to determine the nature of the caesarean section performed on 31 October 1978. That evidence, primarily, was as follows:
(a) Dr Simpson, who delivered the plaintiff, was an experienced obstetrician and gynaecologist. He recorded in his operation note "Ruptured uterus - previous classical caesarean section";
(b) Dr Booth, who assisted at the plaintiff's delivery, was also of the opinion there had been a rupture of a previous classical caesarean section. She gave evidence that on operation she observed adhesions from the bladder to the uterus;
(c) The histopathology report dated 23 October 1984 stated:
MACROSCOPIC
… There is a ragged longitudinal tear running the full length of the anterior wall of the uterus. On each side of the tear there are dense adhesions on the surface of the uterus. Along one edge of the tear there is a smooth depressed area suggestive of old scar tissue. The lining of the uterus is roughened.
MICROSCOPIC
Sections from the lining of the uterus show some residual decidua. The myometrium generally shows mild oedema. Sections from the torn areas confirm the presence of adhesions on the surface and also show some fibrosis and degenerate muscle. The endocervical tissue is oedematous and congested, and also shows a moderate acute inflammatory infiltrate. The distribution of adhesions and fibrosis is consistent with the history of previous classical caesarean section.
(d) Mr Clements gave evidence that the pathology report established the uterine incision extended considerably into the upper segment and the adhesions from the bladder to the uterus were consistent with a vertical incision to the lower segment. He concluded on the balance of probabilities that the caesarean section performed at the delivery of Wassif was a classical caesarean section. He saw nothing in the pathology report which led him to conclude the incision was other than vertical.
(e) Dr Lyneham, largely relying upon the report of adhesions from bladder to uterus, considered it extremely likely that the predominant part of the incision had been to the lower segment though he accepted that an incision to the lower segment may well have extended to the upper segment of the uterus.
(f) Dr Molloy considered there had been a transverse incision of the lower segment which extended vertically into the upper segment.
47 In my opinion, the probabilities favour the conclusion that the caesarean section involved a vertical incision into the lower segment of the uterus which extended vertically into the upper segment, and I so find.
Was TK given appropriate advice and warnings in respect of the operation and its consequences?
48 The alleged breaches by the third defendant are particularised in the Further Amended Statement of Claim, dated 19 December 2006, in the following terms:
(a) Failing to advise the Plaintiff's mother of the high risk following classical caesarean section.
(b) Failing to advise the Plaintiff's mother of the need to inform her present and future treating practitioners of the fact that she had undergone a delivery by classical caesarean section.
(c) Failing to advise the Plaintiff's mother's treating practitioners of the fact that she had undergone a delivery by classical caesarean section.
(d) Failing to warn the Plaintiff's mother that she had or may have a significantly higher than normal risk of uterine rupture in late pregnancy or during birth.
(e) Failing to warn the Plaintiff's mother that future vaginal delivery was contra-indicated due to the significantly higher than normal risk of uterine rupture in late pregnancy or during birth consequent upon her having undergone a delivery by classical caesarean section.
49 It was common ground among the medical experts, and the third defendant accepted, that reasonable care required that a patient upon whom a classical caesarean section was performed should be informed at the hospital where the operation took place of the nature of the procedure performed, and the risks arising from that procedure in the event of future pregnancy. She should be advised that she should inform those treating her for subsequent pregnancies of the nature of the procedure performed. Such advice and warnings should be clear and appropriate efforts should be made to ensure they were understood. Similar advice and warnings were required where an incision into the lower segment of the uterus extended vertically into the upper segment.
50 It was submitted that PANCH should have given such information to TK both orally and in writing. No written document containing such information was given to TK. Dr Bhardwaj gave evidence it was not the practice in 1978, or today, to give patients a written document setting out details of the procedure performed and advice and warnings as to any consequences resulting therefrom. Mr Clements gave evidence that it was a common, but not uniform, practice to provide a written record for the patient. In my opinion it has not been established that there was a duty in 1978 to provide a written record to the patient. Further, there was no direct evidence any such document would have been retained by TK particularly with her move interstate nor was it established that if such document had been retained by TK and given to the hospital it would have resulted in the harm to the plaintiff being avoided.
