Deimplementation of Routine Maternal Oxygen Supplementation for Intrauterine Fetal Resuscitation: A Retrospective Cohort Study.

Objective:  Current practice guidelines for laboring patients with category II intrapartum tracings recommend maternal oxygen supplementation despite emerging randomized data challenging its benefit and utility. We aim to validate that de-implementing maternal oxygen supplementation for fetal resuscitation did not increase the risk of neonatal acidemia in a real-world setting.

Study Design:  This is a retrospective observational study conducted at a single tertiary care center from January 2019 to June 2021.
