What is Effectiveness of Maternal Oxygen Supplementation for Intrauterine Fetal Resuscitation: a Hospital-based Retrospective Study about?

OBJECTIVE: Routine maternal oxygen supplementation for category 2 intrapartum fetal heart rate tracings has not been shown to reduce fetal acidemia in prospective studies. We aim to validate that deimplementing this intervention did not increase the risk of neonatal acidemia in a real-world setting. STUDY DESIGN: This is a retrospective, single-institution study of laboring patients with category 2 intrapartum tracings from January 2019 e June 30, 2021. In March 2020, secondary to the COVID pandemic, routine maternal oxygen supplementation for such tracings was abandoned per hospital guidelines, providing the opportunity to compare pre-and post-de-implementation cohorts. Laboring patients with singleton or twin pregnancies between 23-42 weeks of gestational age with persistent category 2 tracings, as identified by a previously described external safety monitoring system, were evaluated. Major fetal anomalies, contraindications to labor and maternal indication for O 2 supplementation were excluded. The primary outcome was fetal acidemia, defined as umbilical cord pH < 7.2. Secondary outcomes included severe acidemia (pH < 7.0), 5-minute Apgar score < 4 and neonatal intensive care un
