Prospective randomised multicentre trial with the birth traine...

BACKGROUND: In several non-randomised trials training with EPI-NO increased the rate of intact perineum and decreased episiotomy rates, shortened the second stage of labour and lowered use of pain killers. AIMS: To verify the preliminary results with EPI-NO in a prospective randomised trial. METHODS: Randomised, single-blind multicentre trial in four university hospitals in Germany including 276 primigravidae. RESULTS: After training with EPI-NO we observed a significant increase in the incidence of intact perineum (37.4% vs 25.7%; P = 0.05) and a tendency towards lower episiotomy rates (41.9% vs 50.5%; P = 0.11). We found no significant differences between the two groups regarding incidence of perineal tears, duration of second stage of labour, use of pain relief and rate of vaginal infection. CONCLUSIONS: Training with EPI-NO increases significantly the likelihood of having an intact perineum and reduces the episiotomy rate.
