Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed. Participants will be enrolled during antenatal clinics/consultations. The randomisation will take place when/if they present for an emergency caesarean section. Thus the chronology conceals the allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerised randomisation schedule

Efficacy
Statistical methods / analysis
A power calculation was performed assuming a 21% rate of PPH following emergency caesarean section, and a clinically significant benefit reducing that rate to 10%.
This produced a sample size of 220 per arm, with some inflation for potential missing data.

Data analysis:
The primary outcome (Presence of PPH) will be assessed between the intervention and control groups using a chi-squared statistic. Other statistical analyses will be as follows:
Continuous variables will be summarised as mean and standard deviation (SD) for normally distributed variables, and median and interquartile range (IQR) in cases of non-parametric distribution. Categorical variables will be presented as frequencies (n) and proportions (%).
Continuous variables will be assessed using the Student’s t-test, whilst skewed or categorical data will use the chi-squared test or Fisher’s exact test (if any cell is <5). Non-parametric ordinal and continuous data will be assessed with Mann Whitney U Test.

Summary
Brief summary
This study seeks to find out whether giving an injection into the thigh (called Syntometrine - a combination of two uterus-contracting drugs) after an emergency caesarean section delivery will reduce the rate of excessive bleeding after childbirth. This study will randomly assign participants to receive either Syntometrine or a placebo. Both groups will receive normal care (i.e. standard uterus contracting medications). Our hypothesis is that it will reduce the rate of bleeding, and be well tolerated.
