Brief summary

The trial was to determine the effect of administrating subcutaneous terbutaline prior to emergency caesarean delivery for suspected fetal distress

Detailed description

The trial was a double-blinded, placebo-controlled study using subcutaneous terbutaline for acute tocolysis prior to emergency caesarean delivery in suspected fetal distress. The intervention (subcutaneous terbutaline) was compared to placebo looking at the neonatal and maternal outcomes. The primary outcome was the proportion of babies with neonatal acidosis (based on umbilical artery blood sampling at delivery). Other outcome of interest were the mean cord pH and base excess, the Apgar score at 5 minutes after delivery, he proportion of babies requiring intubation and admission to the Neonatal Intensive Care Unit. The maternal outcomes of interest were the changes in mean arterial pressure (before and after the drug or placebo injection), the maternal heart rate changes, the estimated blood loss, and the hematocrit changes.

Masking description

The participants are randomly assigned a number (generated using an online random number generator) and given an opaque envelope containing instructions for study drug or placebo administration. The envelope will be opened by a nurse who prepared the injection in a treatment room, separated from the Labour Suite. The doctors managing the cases, the surgeons who performed the surgeries, the anaesthetists and the patients themselves were blinded against the injection given
