Background: Perineal damage occurs frequently during childbirth, with severe damage involving injury to the anal sphincter reported in up to 18% of vaginal births.

Methods: In this cross-sectional study from an urban population in northern England (53.

Amniotic fluid embolism.

Curr Opin Obstet Gynecol

April 2003

Purpose Of Review: To review the recent literature on amniotic fluid embolism and how it may influence the clinical management and further study of the condition. Morbidity and mortality from amniotic fluid embolism in the international context will be described, given the recent Confidential Enquiries into Maternal Deaths in the United Kingdom and other studies. With this rare condition we need to look for clues as to how to facilitate diagnosis and improve outcomes.
