Fetal scalp pH and ST analysis of the fetal ECG as an adjunct to CTG. A multi-center, observational study.

Objective: To evaluate the relationships between scalp-pH and CTG plus ST waveform analysis of the fetal ECG (STAN) clinical guidelines as indicators of intrapartum hypoxia in term fetuses born with cord artery acidemia.

Study Design: Data from 6999 term deliveries monitored by the STAN (R) S 21 as part of an EU multi-center study on clinical implementation of the STAN methodology for intrapartum fetal surveillance were analyzed. We identified 911 cases where a scalp-pH was obtained, including 53 cases with cord artery acidemia (pH < 7.

Intraoperative surgical complication during cesarean section: an observational study of the incidence and risk factors.

Background: The study was intended to estimate the incidence of intraoperative surgical complications with the impact of the educational level of the surgeon and a history of previous cesarean section on intraoperative complications at cesarean childbirth.

Methods: In the period between August 1st 1995 and July 30th 1996, 7782 women gave birth at the three Obstetric Departments in Copenhagen County, Denmark, of which 929 (11.9%) were delivered by cesarean section.
