Abstract Objective To determine whether discontinuing oxytocin stimulation in the active phase of induced labour is associated with lower caesarean section rates. Design International multicentre, double blind, randomised controlled trial. Setting Nine hospitals in Denmark and one in the Netherlands between 8 April 2016 and 30 June 2020. Participants 1200 women stimulated with intravenous oxytocin infusion during the latent phase of induced labour. Intervention Women were randomly assigned to have their oxytocin stimulation discontinued or continued in the active phase of labour. Main outcome measure Delivery by caesarean section. Results A total of 607 women were assigned to discontinuation and 593 to continuation of the oxytocin infusion. The rates of caesarean section were 16.6% (n=101) in the discontinued group and 14.2% (n=84) in the continued group (relative risk 1.17, 95% confidence interval 0.90 to 1.53). In 94 parous women with no previous caesarean section, the caesarean section rate was 7.5% (11/147) in the discontinued group and 0.6% (1/155) in the continued group (relative risk 11.6, 1.15 to 88.7). Discontinuation was associated with longer duration of labour (median from randomisation to delivery 282 v 201 min; P<0.001), a reduced risk of hyperstimulation (20/546 (3.7%) v 70/541 (12.9%); P<0.001), and a reduced risk of fetal heart rate abnormalities (153/548 (27.9%) v 219/537 (40.8%); P<0.001) but rates of other adverse maternal and neonatal outcomes were similar between groups. Conclusions In a setting where monitoring of the fetal condition and the uterine contractions can be guaranteed, routine discontinuation of oxytocin stimulation may lead to a small increase in caesarean section rate but a significantly reduced risk of uterine hyperstimulation and abnormal fetal heart rate patterns.

AbstractOver the last 30 years, the caesarean section rate has reached global epidemic proportions. This trend is driven by multiple factors, an important one of which is the use and inconsistent interpretation of the electronic fetal monitoring (EFM) system. Despite its introduction in the 1960s, the EFM has not definitively improved neonatal outcomes, yet it has since significantly contributed to a seven-fold increase in the caesarean section rate. As we attempt to reduce the caesarean rates in the developed world, we should consider focusing on areas that have garnered little attention in the literature, such as physician sensitization to the poor predictive power of the EFM and the research method biases that are involved in studying the abnormal heart rate patterns—umbilical cord pH relationship. Herein, we apply Bayes theorem to different clinical scenarios to illustrate the poor predictive power of the EFM, as well as shed light on the principle of protopathic bias, which affects the classification of research outcomes among studies addressing the effects of the EFM on caesarean rates. We propose and discuss potential solutions to the aforementioned considerations, which include the re-examination of guidelines with which we interpret fetal heart rate patterns and the development of noninvasive technologies that evaluate fetal pH in real time.

In most high-income countries, including Canada, the share of births by Caesarean section (C‑section) has risen over the past decades to far exceed World Health Organization recommendations of the proportion justified on medical grounds (15 percent). Although unnecessary C-sections represent an important cost for health care systems, they are not associated with clear benefits for the mother and the child and can sometimes represent additional risks. Drawing on administrative records of nearly four million births in Canada, as well as macro data from the United States and Australia, we provide a comprehensive account of rising C-section rates. We explicitly consider the contributions of the main factors brought forward in the policy literature, including changing characteristics of mothers, births, and physicians as well as changing financial incentives for C-section deliveries. These factors account for at most one-half of the increase in C-section rates. The majority of the remaining increase in C-sections over the period 1994–2011 occurred in the early 2000s. We suggest that some event or shock in the early 2000s is likely the primary determinant of the recent strong increase in the C-section rate in Canada.

Background : Caesarean section is often perceived to be safer than vaginal delivery for mothers and neonates, and thus has become increasingly common around the globe. However, it may actually be detrimental to maternal and neonatal health while consuming valuable resources. Objective : The objective of this study was to categorize the caesarean sections performed in our rural institute into various categories using NICE classification and to study the maternal and neonatal outcome in them. Method : This was a prospective study of all women who underwent caesarean section over a period of 18 months. Data was retrieved from the files of women for morbiditiy and mortality in mothers and babies. Data was entered in MS excel sheet and analyzed with percentages and chi square test using SPSS ver.17. Results: Caesarean section rate (CSR) was 36.88%. All CS were classified into four categories based on urgency as per NICE guidelines. There were 22.62% women in Category I, 38.61% in category II, 28.37% in category III and 10.40% in Category IV. Adhesions, extension of angle, lacerations in lower segment, scar dehiscence, atonic PPH and bladder injury were noted in (12.83%), 11.81%, 6.83%, 4.08% , 1.53% and 0.08% CS respectively. Caesarean hysterectomy was done in 0.24% cases. Postoperative morbidity was febrile morbidity (11.93%), postdural puncture headache (13.85%), paralytic ileus (11.49%), wound infection (8.83%), ARDS (0.70%), sepsis (0.78%), pulmonary edema (0.47%) and pulmonary embolism (0.03%). Maternal mortality was 0.03%. Neonates born were 2577 (29 were twin deliveries). 82.46% neonates were healthy, 16.80% had morbidities and 0.74% were still born. Apgar score of less than 7 was in 10%. 16.80% neonates were admitted in NICU during their hospital stay. Neonatal mortality was 1.47%. Conclusion : Intraoperative and post-operative complication were more in caesarean sections of category I and II as compared to category III and category IV. Neonatal morbidity, mortality and admissions to NICU were more in caesarean sections of category I and II as compared to category III and category IV. Thus though caesarean section is an emergency lifesaving procedure for mother and baby it may prove detrimental to their health.
