Article Synopsis
  • * Early interventions included natural remedies like castor oil in Egypt and mechanical methods from Hippocratic practices around 2500 years ago, transitioning to pharmacological options in the mid-20th century.
  • * Today's IOL methods focus on key factors like effectiveness, safety, cost, and client satisfaction, with ongoing research and evidence from randomized controlled trials shaping future practices.

Background: Induction of labor (IOL) is an increasingly common intervention, but experiences and preferences of induction methods are under-researched particularly in low -and middle-income countries. Understanding these perspectives is important to improve the childbirth experience.

Objective: To explore the experiences and preferences of IOL methods for women, clinicians, and researchers in the "Misoprostol or Oxytocin for Labour Induction" (MOLI) study.

Design: Mixed-methods cross-sectional study.

Setting: Three districts in Ghana and two in Uganda.

Article Synopsis
  • - The study aimed to determine if low-dose oral misoprostol is more effective than intravenous oxytocin in continuing uterine stimulation after cervical ripening and membrane rupture in women induced for hypertensive pregnancy issues.
  • - In a trial involving 520 women, results showed that the caesarean section rates were not significantly different between the two groups, and the time from randomization to birth was longer for those receiving misoprostol.
  • - Although there were no major safety concerns like hyperstimulation, fewer babies required special care in the misoprostol group, and there were no neonatal deaths reported compared to three in the oxytocin group.

Objective: There are no globally agreed on strategies on early detection and first response management of postpartum haemorrhage (PPH) during and after caesarean birth. Our study aimed to develop an international expert's consensus on evidence-based approaches for early detection and obstetric first response management of PPH intraoperatively and postoperatively in caesarean birth.

Design: Systematic review and three-stage modified Delphi expert consensus.

Objectives: To examine modern media depictions of the third stage of birth in a selection of UK television representations.

Design: Observational study of a sample of televised fictional and real births, audited against current National Institute of Health and Social Care Excellence (NICE) guidance.

Setting: UK television channels BBC ( and ) and Channel 4 ().

Background: In high resource settings, lactate and pH levels measured from fetal scalp and umbilical cord blood are widely used as predictors of perinatal mortality. However, the same is not true in low resource settings, where much of perinatal mortality occurs. The scalability of this practice has been hindered by difficulty in collecting fetal scalp and umbilical blood sample.

Background: We evaluated the safety, efficacy, and acceptability of a new device designed to facilitate uterine compression in women with postpartum haemorrhage (PPH).

Methods: A prospective, phase two clinical device trial with concurrent qualitative study, conducted in a UK consultant obstetric unit. The device was used in addition to standard care in women unresponsive to initial oxytocin therapy.

Increasingly, births around the world are started artificially using medications or other methods. This process is known as induction of labour. As it becomes more common, methods are needed to meet the different clinical needs and birth preferences of women.

The World Health Organization (WHO) recently published a new recommendation on the use of the uterine balloon tamponade for the treatment of postpartum hemorrhage. The recommendation that uterine balloon tamponade should be used only where there is already access to other postpartum hemorrhage treatments (including immediate recourse to surgery) has proved controversial. It is especially problematic for those working in low-level health care facilities in under-resourced settings, where there are already programs that have introduced low-cost uterine balloon tamponade devices for use, even in settings where recourse to surgical interventions is not possible.

Misoprostol for labour induction.

Best Pract Res Clin Obstet Gynaecol

November 2021

Oral and vaginal misoprostol are effective induction methods, but there is a delicate balance between a quicker labour and avoiding side effects. In randomised comparisons with balloon catheters, oral misoprostol resulted in more vaginal births in the first 24 h as well as fewer caesarean sections without an increase in hyperstimulation events. Vaginal misoprostol was most effective when used concurrently with a balloon catheter.

The composition of the maternal vaginal microbiome influences the duration of pregnancy, onset of labor, and even neonatal outcomes. Maternal microbiome research in sub-Saharan Africa has focused on non-pregnant and postpartum composition of the vaginal microbiome. Here we aimed to illustrate the relationship between the vaginal microbiome of 99 laboring Ugandan women and intrapartum fever using routine microbiology and 16S ribosomal RNA gene sequencing from two hypervariable regions (V1-V2 and V3-V4).

Objectives: Induction of labour (IOL), or starting labour artificially, can be a lifesaving intervention for pregnant women and their babies, and rates are rising significantly globally. As rates increase, it becomes increasingly important to fully evaluate all available data, especially that from low income settings where the potential benefits and harms are greater. The goal of this paper is to describe the datasets collected as part of the Induction with Foley OR Misoprostol (INFORM) Study, a randomised trial comparing two of the recommended methods of cervical ripening for labour induction, oral misoprostol and Foley catheter, in women being induced for hypertension in pregnancy, at two sites in India during 2013-15.

Background: In Uganda, the incidence and determinants of perinatal death in obstructed labour are not well documented. We determined the incidence and determinants of perinatal mortality among women with obstructed labour in Eastern Uganda.

Methods: Between July 2018 and September 2019, 584 with obstructed labour were recruited and followed up to the 7th day postnatal.

Objective: To evaluate the predictive capacity of vital signs for the diagnosis of postpartum hemorrhage (PPH).

Methods: A prospective cohort study performed at the University of Campinas, Brazil, between February 2015 and March 2016 with women who delivered vaginally. Vital signs and postpartum bleeding were collected over 24 h.

The initial bedside care of premature babies with an intact cord has been shown to reduce mortality; there is evidence that resuscitation of term babies with an intact cord may also improve outcomes. This process has been facilitated by the development of bedside resuscitation surfaces. These new devices are unaffordable, however, in most of sub-Saharan Africa, where 42% of the world's 2.

Background: Misoprostol given orally is a commonly used labour induction method. Our Cochrane Review is restricted to studies with low-dose misoprostol (initially ≤ 50 µg), as higher doses pose unacceptably high risks of uterine hyperstimulation.

Objectives: To assess the efficacy and safety of low-dose oral misoprostol for labour induction in women with a viable fetus in the third trimester of pregnancy.

Background: Retained placenta is a common complication of pregnancy affecting 1% to 6% of all births. If a retained placenta is left untreated, spontaneous delivery of the placenta may occur, but there is a high risk of bleeding and infection. Manual removal of the placenta (MROP) in an operating theatre under anaesthetic is the usual treatment, but is invasive and may have complications.

Introduction: Oral bicarbonate solution is known to improve both maternal and perinatal outcomes among women with abnormal labour (dystocia). Its effectiveness and safety among women with obstructed labour is not known.

Objective: To determine the effect and safety of a single-dose preoperative infusion of sodium bicarbonate on maternal and fetal blood lactate and clinical outcomes among women with obstructed labour (OL) in Mbale hospital.

Background: Postpartum haemorrhage (PPH), defined as a blood loss of 500 mL or more after birth, is the leading cause of maternal death worldwide. The World Health Organization (WHO) recommends that all women giving birth should receive a prophylactic uterotonic agent. Despite the routine administration of a uterotonic agent for prevention, PPH remains a common complication causing one-quarter of all maternal deaths globally.
