RESUMO
The coronavirus disease 2019 (COVID-19) pandemic drove many healthcare systems worldwide to postpone elective surgery to increase healthcare capacity, manpower, and reduce infection risk to staff. The aim of this study was to assess the impact of an elective surgery postponement policy in response to the COVID-19 pandemic on surgical volumes and patient outcomes for three emergency bellwether procedures. A retrospective cohort study of patients who underwent any of the three emergency procedures [Caesarean section (CS), emergency laparotomy (EL), and open fracture (OF) fixation] between 1 January 2018 and 31 December 2021 was conducted using clinical and surgical data from electronic medical records. The volumes and outcomes of each surgery were compared across four time periods: pre-COVID (January 2018-January 2020), elective postponement (February-May 2020), recovery (June-November 2020), and postrecovery (December 2020-December 2021) using Kruskal-Wallis test and segmented negative binomial regression. There was a total of 3886, 1396, and 299 EL, CS, and OF, respectively. There was no change in weekly volumes of CS and OF fixations across the four time periods. However, the volume of EL increased by 47% [95% confidence interval: 26-71%, P = 9.13 × 10-7) and 52% (95% confidence interval: 25-85%, P = 3.80 × 10-5) in the recovery and postrecovery period, respectively. Outcomes did not worsen throughout the four time periods for all three procedures and some actually improved for EL from elective postponement onwards. Elective surgery postponement in the early COVID-19 pandemic did not affect volumes of emergency CS and OF fixations but led to an increase in volume for EL after the postponement without any worsening of outcomes.

Postpartum haemorrhage (PPH) is an obstetric emergency and a leading cause of severe maternal morbidity and mortality. Timely and accurate diagnosis of the underlying cause of PPH is critical in achieving optimal care for the patient as any potential delays may result in severe morbidity and even mortality. We present a rare case of a patient presenting with PPH secondary to acquired haemophilia. This case highlights the importance of early diagnosis and multidisciplinary management in achieving optimal management of this complex condition.

Introduction: There has been a global decrease in operative vaginal deliveries, with a marked shift towards the vacuum extractor. However, little is known about the trends in operative vaginal delivery in Singapore. Methods: A retrospective study was conducted on all operative vaginal deliveries performed from 2012 to 2017 at Singapore General Hospital (SGH). Maternal outcomes in terms of postpartum haemorrhage and obstetric anal sphincter injuries were compared between forceps- and vacuum-assisted deliveries. Neonatal outcomes in terms of neonatal intensive care unit (NICU) admission and clinically significant neonatal events were compared. The instrument preference of obstetricians was analysed. Results: A total of 906 consecutive operative vaginal deliveries were included in the study, comprising 461 forceps- and 445 vacuum-assisted deliveries. The rate of operative vaginal delivery was maintained at approximately 10% from 2012 to 2017. Neonatal cephalohematomas were more common after vacuum-assisted deliveries. Other maternal and neonatal outcomes did not differ significantly between the two groups. Clinically significant neonatal events were mostly due to shoulder dystocia, whereas all cases of NICU admissions were not directly related to the mode of delivery. Obstetricians' choice of instrument appeared to reflect personal preference and was not affected by the year of graduation. Conclusion: The rates of neonatal and maternal morbidity were low at SGH. Overall instrument use of forceps and vacuum was balanced, and proficiency in both was demonstrated by all operators. Operative vaginal delivery remains an essential skill in facilitating safe vaginal delivery, which should be maintained to keep Caesarean section rates in check.

We present a case of a woman at 31 weeks and 3 days of gestation, who developed a sudden and severe headache and loss of vision in her left eye. Magnetic resonance imaging (MRI) of the brain revealed a subarachnoid bleed secondary to a right parieto-occipital arteriovenous malformation (AVM). She was conservatively managed and subsequently transferred to our institution for multidisciplinary care. The patient underwent a cesarean section at 34 weeks and 5 days of gestation followed by gamma knife surgery 6 days after. Cerebral AVMs, although relatively rare, have the propensity to cause potentially fatal outcomes. Neurological symptoms in a pregnant woman warrant investigations for early diagnosis and management, due to its associated morbidity and mortality. The management of cerebral AVMs in pregnancy is decided after weighing the benefits of treatment against the risk of bleeding. A multidisciplinary approach should be adopted due to the complexity of the condition.
RESUMO
INTRODUCTION AND HYPOTHESIS: Forceps-assisted deliveries are an established risk factor for pelvic organ prolapse and pelvic floor injury. However, specific comparison of incontinence outcomes between vacuum-assisted and forceps-assisted deliveries are scarce in the literature. We aimed to compare the initial impact of vacuum and forceps deliveries on new-onset urinary and faecal incontinence as well as pelvic floor muscle strength, with the hypothesis that incontinence outcomes were poorer after forceps- than after vacuum-assisted delivery. METHODS: This is a retrospective cohort study of incontinence outcomes in patients who had primary vacuum- or forceps-assisted delivery. The study population included 108 postpartum patients who had undergone operative vaginal delivery (63 vacuum-assisted, 45 forceps-assisted), met the inclusion criteria and attended the postpartum assessment service. Outcomes studied were the presence and severity of symptoms manifesting beyond 1 month postpartum - faecal incontinence and stress, urgency and mixed urinary incontinence - as well as pelvic floor muscle strength scores based on the modified Oxford scale. RESULTS: Prevalence of new-onset urinary and faecal incontinence was 35.6% in the forceps group and 30.2% in the vacuum group. The data suggest that there is no significant difference in the prevalence of new-onset incontinence symptoms (p = 0.70, difference in prevalence [forceps - vacuum]: 5.4%, 95% CI -0.25, +0.15), frequency (p = 0.40) and amount (p = 0.48) of urine leakage or mean muscle strength scores (p = 0.89). CONCLUSION: In our maternity unit, we observed that type of operative vaginal delivery was not associated with significant differences in urinary incontinence and pelvic floor muscle strength outcomes.

A woman in her early twenties with dichorionic diamniotic twins underwent emergency caesarean section (CS) for failed induction of labor for discordant growth at 37 weeks. Her CS was complicated by atonic postpartum hemorrhage (PPH) requiring uterotonics, B-lynch suture, and Bakri balloon. She presented on the 5th postoperative day (POD) with fever and wound pain and collapsed due to desaturation. Investigations confirmed ascites on computed tomography (CT) of her abdomen and cardiomyopathy on echocardiogram. She was readmitted on the 22nd POD with watery vaginal discharge. CT abdomen revealed a dehisced CS scar and loculated ascites. Her discharge settled after three weeks with antibiotics and drainage of the ascites. A CT scan 3 months later showed reduction of the peritoneal collection. Caesarean scar dehiscence should be considered for patients presenting with ascites and vaginal discharge after a CS, particularly in the presence of risk factors such as infection or anemia.
RESUMO
Diabetic ketoacidosis (DKA) during pregnancy is a serious metabolic complication of diabetes with high mortality and morbidity if not detected and treated immediately. We report a case of a woman with type 1 diabetes mellitus who had poorly controlled diabetes in the first half of pregnancy and developed DKA at 29 weeks gestation. At presentation, she had a pathological fetal heart tracing but delivery was delayed for maternal stabilisation and reversal of acidosis. Once hyperglycaemia, acidosis and maternal stabilisation were achieved, fetal compromise resolved and delivery was no longer indicated. The patient was subsequently discharged home. She delivered vaginally a 2400 g baby at 34 weeks gestation after presenting with spontaneous rupture of membranes.

INTRODUCTION: Although Caesarean sections (CSs) are among the most commonly undertaken procedures in the world, there are wide variations in the surgical techniques used. This study aimed to: (a) review the surgical techniques used for CS by obstetricians working in a tertiary hospital in Singapore; (b) compare the techniques with those recommended in evidence-based guidelines; and (c) examine the relationship between the technique used and the level of seniority of the surgeons. METHODS: Data on 490 CSs performed in Singapore General Hospital (SGH) between 1 August 2013 and 30 June 2014 was collected from the Delivery Suite database and reviewed. The surgical techniques studied were closure of the pelvic and parietal peritoneum, closure of the uterine layer, use of surgical drains and use of postoperative thromboprophylaxis. RESULTS: A total of 486 CSs were analysed after four cases were excluded due to missing data. Most fetal head deliveries were manual. The majority of surgeons did not close the peritoneum; most of those who did were senior surgeons. Double-layer uterine closures were done for all cases and drain usage was rare. 2.0% of the patients received grossly inadequate thromboprophylaxis. CONCLUSION: The surgical techniques currently practised in SGH are closely aligned with those of the evidence-based guidelines. Peritoneal closure appears to be associated with the surgeon's early training, with a greater number of senior surgeons being less willing to abandon this step. Greater vigilance in implementing appropriate thromboprophylaxis is recommended.

INTRODUCTION: This study aimed to determine the decision-to-delivery intervals (DDIs), total duration of surgery and factors influencing these for Caesarean sections (CSs). METHODS: A retrospective study was conducted of all CSs performed from August 2013 to June 2014 at a single tertiary general hospital. Data collected included maternal demographics, indications for CS, category of urgency, DDI, total duration of surgery, grade of first surgeon and number of previous CSs. RESULTS: In total, 488 CSs (Category 1: n = 28; Category 2: n = 137; Category 3: n = 184; Category 4: n = 139) were studied. Overall mean duration of surgery was 41.7 minutes. Mean DDI was 23.9 minutes and 64.5 minutes for Category 1 and Category 2 CSs, respectively. For Category 1 CSs, deliveries during office hours had a significantly shorter DDI than deliveries out of office hours (p < 0.05). For Category 2 CSs, deliveries during office hours had a significantly longer DDI (p < 0.05). Total duration of surgery for senior surgeons was significantly shorter than for trainee surgeons (p < 0.05). Women with no previous CSs had a significantly shorter duration of surgery than those who had one or more (p < 0.05). CONCLUSION: The majority of the deliveries were within the recommended DDI corresponding to the degree of urgency of CS. The influence of time of day on DDI might be due to challenges of time taken to transfer patients to operating theatres. Total duration of surgery was influenced by surgical experience, history of previous CS and individual surgical styles and preferences.

AIM: In vitro fertilization (IVF) pregnancy is an important contributor to rising cesarean section (CS) rates. The profile of CS in this group is not well documented. This study sought to identify leading patient categories of the Robson 10-Group Classification System (TGCS) contributing to the high IVF CS rate. METHODS: We carried out a prospective study of IVF patients who delivered in the Singapore General Hospital from January 2010 to July 2012. Parity, singleton/multiple pregnancy, previous CS, mode of labor onset and gestational age at delivery were collected based on the TGCS. All other deliveries during the study period served as control. RESULTS: There were a total of 215 IVF deliveries, of which 114 (54.4%) were CS. Group 8 (all multiple pregnancies) was the greatest contributor to the overall CS rate (43.0%). Group 2 (term nulliparous singleton cephalic pregnancies with induction of labor or planned CS) was the second largest contributor to overall CS rate (12.3%). The third and fourth leading contributors were Group 10 (preterm singleton pregnancies) and Group 5 (pregnancies with previous CS), respectively. In contrast, these two groups were top contributors to the overall CS rate for the control group. CONCLUSION: Multiple pregnancy is the principal contributor to CS in our IVF population, and reducing its incidence may reduce its CS rate. Among singleton pregnancies, planned CS and failed induction for cephalic term pregnancies and preterm singleton pregnancies were the next largest contributors, suggesting a higher prevalence of maternal request and high-risk obstetric indications requiring interventions at preterm gestations.

AIM: Renal and obstetric outcomes in pregnancy after kidney transplantation in Singapore were last studied in 2002. A review of these outcomes in Singapore is now timely following advances in transplant and obstetric medicine. The aim was to evaluate the renal and obstetric outcomes in pregnancy after kidney transplantation in a Singapore tertiary center. METHODS: Kidney transplant recipients who underwent pregnancy after transplantation at Singapore General Hospital between January 2001 and December 2012 were identified. Data on demographics, comorbidities and clinical outcomes were collected. RESULTS: There were 10 pregnancies identified in nine recipients. The median age of recipient at childbearing was 34.6 years (IQR, 32.8-36.8) and the median interval from transplantation to conception was 69 months (IQR, 38-97). There was no difference between the median pre-pregnancy estimated glomerular filtration rate (eGFR) (47.9 mL/min/1.73 m(2); IQR, 38.4-56.8) and median eGFR at time of last post-partum follow up (43.9 mL/min/1.73 m(2); IQR, 34.5-48.7, P = 0.549). Borderline allograft rejection occurred in one recipient (10.0%) 36 days after birth due to non-adherence to immunosuppressive medication, with subsequent allograft loss 37 months after birth. No mortalities were recorded during the study period. All the 10 pregnancies (100%) ended in singleton live births. Pre-eclampsia occurred in five pregnancies (50.0%), and there were seven (70.0%) preterm deliveries. The median gestational age was 35.4 weeks (IQR, 32.6-38.2) and the median birthweight was 2353 g (IQR, 1811-2648). CONCLUSION: Post-transplantation pregnancies ended successfully with no significant worsening of allograft function, but they were associated with risks to both recipients and newborns.

INTRODUCTION: In the United Kingdom, caesarean section (CS) rates have increased from 9% of deliveries in 1980 to 21% in 2001. A similar increase in CS rates has been seen in many developed countries. This is beyond the World Health Organisation's (WHO's) recommended level of 15%. This is a worrying trend as the risks of placenta previa, placenta accreta, hysterectomies, bladder and bowel injuries are increased with subsequent CS. We aim to ascertain the commonest indications for CS in a tertiary hospital and make recommendations to decrease future CS rates. MATERIALS AND METHODS: This retrospective analysis compares the 5 most common indications for CS in 1999 and 2009. CS rates in the 2 study periods are tabulated and analysed as well. RESULTS: In the first study period between January and December 1999, there were 2048 deliveries of which 365 were via CS. In the second study period of a decade later from January to December 2009, there were 1572 deliveries of which 531 were via CS. This gives an increase in CS rate from 17.8% in 1999 to 34% in 2009. The main indications for CS in 1999 were: cephalopelvic disproportion (18.6%), breech (14.2%), non-reassuring fetal status (11.8%), 1 previous CS (11.2%) and pregnancy-induced hypertension/pre-eclampsia/eclampsia (6.6%). The main indications for CS in 2009 were: 1 previous CS (18.1%), non-reassuring fetal status (12.2%), cephalopelvic disproportion (10.5%), 2 or more previous CS (7.9%) and breech (7.7%). CONCLUSION: There is a significant increase in CS rates over the last decade with an increased percentage of CS done because of a previous CS. This is associated with increased risk of complications as well. Recommendations are suggested with the view to decrease future CS rates.

Cervical stenosis is a challenging condition that often recurs despite intervention. Multiple therapeutic options have been described, but a clearly effective and reliable treatment method has yet to be identified. Patients with recurrent stenosis are at risk of developing severe complications such as chronic pelvic pain and infertility. We describe a case of congenital cervical stenosis with secondary haematometra in which repeated cervical dilatation, hysteroscopic canalisation and administration of medications to retard endometrial development were unsuccessful in relieving the obstruction and preventing re-accumulation of menstrual blood. Total hysterectomy was eventually mandated by spontaneous rupture of the haematometra.

C(w) is a low-frequency antigen in the Rhesus blood group system. Anti-C(w) can occur naturally or develop as a result of red blood cell sensitization through transfusion or pregnancy. Clinically significant hemolytic disease of the newborn is rarely associated with anti-C(w), with no previous reported cases of hydrops fetalis or severe fetal anemia resulting in intrauterine death. We report an unusually severe case of intrauterine hemolysis resulting from this rare condition. The neonate presented with early-onset hyperbilirubinemia and severe anemia at birth requiring multiple exchange transfusions in the first 24 hours of life. The mother of this infant had a significantly poor obstetric history, having delivered a stillbirth with massive hepatosplenomegaly previously. This case report suggests that intrauterine hemolysis due to anti-C(w) may be life threatening to the unborn fetus.
