One thousand one hundred and fifty monitored labors were studied. Endometritis was rare and postpartum febrile morbidity could not be attributed directly to the direct technics used for intrapartum monitoring. Three asymptomatic uterine perforations were encountered with the transcervical intrauterine catheter. Two of these were found incidently at cesarcan section and an additional suspected perforation was confirmed radiologically. There were no complications from these perforations. Scalp abscess and major fetal morbidity due to the application of the electrode were not seen in this study. There were 2 intrapartum stillbirths among the monitored labors.
