Not only residents, but gynecologists and obstetricians, too….

We have read the original research article by Bergendahl et al on the relation between operator experience and the risk obstetric anal sphincter injuries (OASIS) during vacuum extraction (VE) with interest. The authors raise an issue that is very relevant to current obstetric practice, which is, how to guide junior obstetric professionals through obstetric procedures whilst ensuring that this has no negative impact on maternal and/or fetal risks. However, we think that the authors have missed to address some important issues in their paper. This article is protected by copyright. All rights reserved.
