Risk of third-trimester amniocentesis: a case-control study.

Risks of third-trimester amniocentesis are considered minimal; however, only case series have been reported. We performed a case-control study in which women undergoing third-trimester amniocentesis were matched with controls undergoing antenatal testing for similar indications to determine adverse outcomes associated with the procedure. Cases undergoing amniocentesis at > 32 weeks for fetal lung maturity assessment followed by antepartum testing with nonstress test and amniotic fluid index determination were matched with controls undergoing only antepartum testing based on gestational age at testing and maternal age.

Additional training with an obstetric simulator improves medical student comfort with basic procedures.

Objective: To determine if an obstetric birthing simulator can improve medical student understanding of and comfort with basic obstetric procedures.

Study Design: Medical students were surveyed at the end of their obstetrics rotation regarding their knowledge and comfort with basic obstetric procedures. A group of students was trained on basic procedures utilizing an obstetric simulator.
