Sudden maternal deaths from amniotic fluid embolism

Nadesan K, Jayalakshmi P

Ceylon Med J, 1997 Dec;42(4):185-9.

Sudden maternal death from amniotic fluid embolism is a rare but serious complication which usually occurs during late pregnancy, often during labour or shortly after, with more than 80% mortality. Such a death causes immense stress to both the relatives and the attending doctors as it is sudden and unexpected. Three such deaths are discussed here. Traditionally, it was believed that this complication usually occurred in prolonged and difficult labour, but there is evidence contrary to this, and it is not possible to predict when and where this fatal complication will occur. Current views and various pathophysiologic mechanisms leading to the fatal outcome are also discussed.

Fulltext Spontaneous intra-partum rupture of uterine vein--an uncommon cause of intra-abdominal haemorrhage

Kuppuvelumani P, Rachagan SP, Khin MS

Med J Malaysia, 1994 Jun;49(2):185-6.

PMID: 8090103

A rare case of spontaneous rupture of a branch of the uterine vein in a primigravida is discussed. The patient with an uncomplicated pregnancy presented with signs and symptoms suggestive of abruptio placenta with foetal distress. Lower segment Caesarean section was performed. The cause of acute pain was identified to be intra-abdominal bleeding secondary to the rupture of a branch of the uterine vein. The pathophysiology of the problem is discussed.

Induction of labour with prostaglandin E2 and amniotomy--a multicentre, three dose schedule study in 1533 patients

Karim SM, Lim SM, Ilancheran A, Ratnam SS, Ang LT, Ng KH, et al.

Ann Acad Med Singap, 1982 Oct;11(4):503-7.

PMID: 7165271

Prostaglandin E2 administered orally and combined with amniotomy was used for induction of labour at or near term in 1533 patients. The study was carried out as a collaborative project between the University Departments of Obstetrics and Gynaecology in Singapore, Medan (Indonesia) and Kuala Lumpur (Malaysia). The overall success rates for Medan, Kuala Lumpur and Singapore were 95.6%, 88.1% and 84.7% respectively.

Rupture of the pregnant uterus--a 21-year review

Rachagan SP, Raman S, Balasundram G, Balakrishnan S

Aust N Z J Obstet Gynaecol, 1991 Feb;31(1):37-40.

PMID: 1872771

Uterine rupture is still a common problem in developing countries although even here the incidence varies from urban to rural settings. This article is a review of uterine rupture in an urban referral hospital in Malaysia. It examines aetiology, clinical presentation, complications and management of the problem. Meticulous screening of patients together with optimal antenatal and intrapartum care will markedly reduce the incidence of uterine rupture. Early diagnosis and prompt treatment will further help reduce morbidity and mortality to both mother and fetus.

The 50-g glucose challenge test and pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes

Tan PC, Ling LP, Omar SZ

Int J Gynaecol Obstet, 2009 Apr;105(1):50-5.

PMID: 19154997 DOI: 10.1016/j.ijgo.2008.11.038

OBJECTIVE:
To evaluate the 50-g glucose challenge test (GCT) on pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes (GDM).

METHODS:
GCT was positive if the 1-hour plasma glucose level was >or=7.2 mmol/L. GDM was diagnosed by a 75-g glucose tolerance test using WHO (1999) criteria. Of the 1368 women enrolled in the study, 892 were GCT negative, 308 were GCT false-positive, and 168 had GDM. Pregnancy outcomes were extracted from hospital records. Multivariable logistic regression analysis was performed with GCT negative women as the reference group.

RESULTS:
GCT false-positive status was associated with preterm birth (adjusted odds ratio [AOR] 2.1; 95% CI, 1.2-3.7) and postpartum hemorrhage (AOR 1.7; 95% CI, 1.0-2.7). GDM was associated with labor induction (AOR 5.0; 95% CI, 3.3-7.5), cesarean delivery (AOR 2.2; 95% CI, 1.6-3.2), postpartum hemorrhage (AOR 2.1; 95% CI, 1.2-3.7), and neonatal macrosomia (AOR 2.5; 95% CI, 1.0-6.0).

CONCLUSION:
GCT false-positive women had an increased likelihood of an adverse pregnancy outcome. The role and threshold of the GCT needs re-evaluation.

Sudden maternal deaths in Malaysia: a case report

Jegasothy R

J Obstet Gynaecol Res, 2002 Aug;28(4):186-93.

PMID: 12452259

We report on a retrospective study of maternal deaths in Malaysia that occurred within 24 hours of delivery, abortion or operative termination of the pregnancy (defined as sudden deaths) in the years 1995-1996. There were 131 sudden maternal deaths (20.6% of all maternal deaths); postpartum hemorrhage, obstetric embolisms, trauma and hypertensive disorders of pregnancy were the main causes. There was a disproportionately increased risk of sudden maternal deaths in the Chinese and the 'other bumiputra' racial groups. The proportion of mothers who had no obstetric risk factors in the pregnancy that led to death was 16.8%. Fourteen mothers died in transit Twenty mothers died after a cesarean section. The findings of this review emphasize the fact that caregivers in obstetrics need to be forever vigilant. All maternity staff need to be well trained in emergency care and there needs to be quick referral to centers that can provide expertise in handling these emergencies.

It is the first birth that does the damage: a cross-sectional study 20 years after delivery

Kamisan Atan I, Lin S, Dietz HP, Herbison P, Wilson PD, ProLong Study Group

Int Urogynecol J, 2018 Nov;29(11):1637-1643.

INTRODUCTION AND HYPOTHESIS: Levator ani muscle (LAM) and anal sphincter tears are common after vaginal birth and are associated with female pelvic organ prolapse and anal incontinence. The impact of subsequent births on LAM and external anal sphincter (EAS) integrity is less well defined. The objective of this study was to determine the prevalence of LAM and EAS trauma in primiparous (VP1) and multiparous (VP2+) women who had delivered vaginally to assess if there were differences between the two groups. The null hypothesis was: there is no significant difference in the prevalence of LAM and EAS trauma between the two groups.

METHODS: This was a cross-sectional study involving 195 women, participants of the Dunedin arm of the ProLong study (PROlapse and incontinence LONG-term research study) seen 20 years after their index birth. Assessment included a standardized questionnaire, ICS POP-Q and 4D translabial ultrasound. Post-imaging analysis of LAM and EAS integrity was undertaken blinded against other data. Statistical analysis was performed using Fisher's exact test and results were expressed as odds ratios (OR).

RESULTS: LAM avulsion and EAS defects were diagnosed in 31 (16%) and 24 (12.4%) women respectively. No significant difference in the prevalence of levator avulsion and EAS defects between primiparous (VP1) and multiparous (VP2+) women who had delivered vaginally (OR 1.9, 95% CI 0.72-5.01, p = 0.26) and (OR 1.2, 95% CI 0.4-3.8, p = 0.76) respectively.

CONCLUSIONS: Most LAM avulsions and EAS defects seem to be caused by the first vaginal birth. Subsequent vaginal deliveries after the first were unlikely to cause further LAM trauma.
