[Frequency and criteria for the indication of episiotomy].

This is an exploratory study aimed at identifying the frequency, the types and the criteria adopted to recommend episiotomy. Twelve doctors and 12 nurses who attend women giving birth at the University of São Paulo's Hospital Universitário were interviewed. Episiotomy was performed in 76.2 percent of the normal births; the most frequent indications were: perineal rigidity (28.7 percent), primiparity (23.7 percent), macrossomic infant (11.9 percent) and prematurity (10.2 percent). The most mentioned type was the right medium-lateral (92.0 percent), and the justifications were: it was learned during academic formation (25.9 percent); it is adopted routinely (19.4 percent); with it there is a lesser chance for causing lesions to the anal sphincter (16.1 percent); with it there is a lesser risk of complications (16.1 percent). The practices for attending women giving birth must be revised taking into account scientific evidences and individualized conducts.
