Hysterotomy level at Cesarean section and occurrence of large scar defects: a randomized single-blind trial.

Objective: To study the association between the level of Cesarean hysterotomy and the presence of large uterine scar defects 6-9 months after delivery.

Methods: This was a two-center, randomized, single-blind trial of a surgical procedure with masked assessment of the principal outcome under study. Women without a history of Cesarean section (CS) who underwent emergency CS at cervical dilatation ≥ 5 cm were randomized to high or low incision.

Fetal and maternal temperatures during labor and delivery: a prospective descriptive study.

Objective: The objective of this study is to study the fetal scalp temperature (FST) and maternal axillary temperature (MAT) during vaginal delivery relative to progression of labor, uterine contractions (UC) and epidural analgesia (EDA), and to construct normal temperature reference ranges related to stage of labor.

Material And Methods: Temperatures were recorded continuously in labor of 132 women with a bi-metal temperature sensor attached to the axilla (MAT) and a similar sensor mounted in a scalp electrode (FST). The temperature data were stored electronically and analyzed offline at cervical dilatations of 2-3, 5, 7-8, and 10 cm, and at full retraction.

A perineal protection device designed to protect the perineum during labor: a multicenter randomized controlled trial.

Objective: The objective of this study was to evaluate the protective effects of a new device for reducing perineal tears during vaginal childbirth.

Study Design: A multicenter open randomized controlled trial (RCT) was performed in Helsingborg, Lund and Malmö, Sweden consisting of 1148 women. Women anticipating a vaginal delivery were either randomized to the intervention group (n=574 in which the perineal protection device was used, or a control group (n=574), in which the perineal protection device was not used.

Effects on fetal and maternal temperatures of paracetamol administration during labour: a case-control study.

Objective: To study the effect of paracetamol (acetaminophen) on maternal and fetal temperatures in labour.

Study Design: From a cohort of 185 women with continuous maternal axillary and fetal scalp temperature recordings in labour, 18 women treated with 1000mg paracetamol orally for pyrexia and 36 untreated controls matched for parity, cervical dilatation, and epidural analgesia were selected. Electronically stored temperature data were analysed offline post hoc.
