Association between marked fetal heart rate variability and neonatal acidosis: A prospective cohort study.

ABSTRACT:

Objective

To assess the association between marked variability in fetal heart rate (FHR) and neonatal acidosis.

Design

Bicentric prospective cohort study.

Setting

From January 2019 to December 2019, in two French tertiary care maternity units.

Population

Women in labour at ≥37 weeks of gestation, with continuous FHR monitoring until delivery and with the availability of umbilical arterial pH. Women with intrauterine fetal death or medical termination, multiple pregnancies, non-cephalic presentation or planned caesarean delivery were excluded.

Methods

The exposure was marked variability in FHR in the 60 minutes before delivery, defined as a variability greater than 25 beats per minute, with a minimum duration of 1 minute. To assess the association between
