The effect of intrapartum prolonged oxygen exposure on fetal metabolic status: secondary analysis from a randomized controlled trial.

ABSTRACT:

Objective

The aim of the study is to assess the effect of maternal prolonged oxygen exposure during labor on fetal acid-base status, fetal heart rate tracings, and umbilical cord arterial metabolites.

Design

The study was conducted as a secondary analysis.

Settings

The study was set in three tertiary teaching hospitals in Beijing, China.

Participants

Approximately 140 women in the latent phase of labor with no complications participated in the study.

Intervention

Participants were randomly allocated in a 1:1 ratio to receive either 10 L of oxygen per minute in a tight-fitting simple facemask until delivery or room air only.

Main outcome measures

The primary outcome was the umbilical cord arterial lactate.
