Inpatient versus outpatient management of monoamniotic twins and outcomes.

We sought to evaluate whether early (24 to 28 weeks gestation) hospitalization of monoamniotic twins, with close fetal surveillance, and delivery at 32 to 34 weeks gestation, would significantly improve the perinatal morbidity and mortality compared with an outpatient management strategy. A multicenter, retrospective record review was undertaken. Records of all monoamniotic twins were collected for a 10-year period.

Extramembranous placement of an air-coupled vs. transducer-tipped intrauterine pressure catheter.

Objective: To compare the rate of extramembranous placement between 2 types of intrauterine pressure catheter.

Study Design: Women were randomized to a transducer-tipped intrauterine pressure catheter or an air-coupled intrauterine pressure catheter from October 1998 to August 1999. Women were eligible for the study if their attending physicians decided to place an intrauterine pressure catheter.
