title: Amniotomy and cord prolapse.
abstract: Research shows that artificially rupturing the amniotic sac (amniotomy) can cause umbilical cord prolapse. Amniotomy became a routine part of obstetrical care with the introduction of active management, without evidence of benefit. In the 30 years since active management was introduced, the rate at which amniotomy causes umbilical cord prolapse has not been directly studied. Two controlled studies from Turkey from 2002 and 2006 are the only published studies that provide enough data to extract the rate at which cord prolapse follows amniotomy. They show that 1 cord prolapse results from every 300 amniotomies (0.3%). There is data suggesting amniotomy may also increase neonatal GBS infection, maternal pain and fetal blood loss if placental blood vessels are punctured.
