Implementation of the RCOG guidelines for prevention of obstetric anal sphincter injuries (OASIS) at two London Hospitals: A time series analysis.

Objective: To audit the impact of implementation of the RCOG guidelines for prevention of Obstetric anal sphincter injuries (OASIS) by introducing antenatal perineal massage, manual perineal protection, and cutting episiotomies at 60° to the midline at the time of crowning.

Design: Time series analysis; Setting - Two London teaching hospitals; Royal Free London (RFL) and Barnet; Population or Sample - All nulliparous women undergoing vaginal birth; Methods - Training was provided for above techniques. EPISCISSORS-60 were introduced to perform 60° episiotomies.

Is induced labour in the nullipara associated with more maternal and perinatal morbidity?

Purpose: To ascertain any differences in foetomaternal outcomes in induced and spontaneous labour among nulliparous women delivering at term.

Methods: A retrospective matched cohort study consisting of 403 nulliparous women induced at ≥ 292 days and 806 nulliparous women with spontaneous labour at 285-291 days.

Results: Compared to those in spontaneous labour, women who had induction of labour were three times more likely to have a caesarean delivery (OR 3.
