Intervention
Women who underwent forceps or vacuum delivery after gestation periods of at least 36 weeks were randomised to receive a single prophylactic dose of IV co-amoxiclav provided there were no contraindications. A placebo (0.9% saline) was chosen as the comparator in this economic evaluation as it was in the ANODE trial1. This is because current WHO recommendations state that no antibiotic prophylaxis should be provided following operative vaginal delivery6.
