Brief summary

This study compares the duration of active phase of labour in women who received buscopan and those who don't.

Detailed description

A randomised control study involving primigravida in labour who require pitocin augmentation. Once patient require augmentation, patient will be randomised into intervention group (receiving intravenous buscopan 1ml or 20mg) and control group (intravenous normal saline 1ml). Both fluids are colourless. The primary outcome is duration from augmentation to os fully. The secondary outcome are to look on mode of delivery particularly any caesarean section due to failure to poor progress, maternal side effect (dry mouth and tachycardia) and baby outcome (apgar score and neonatal intensive care unit admission)
