Perioperative Use of Continuous Glucose Monitoring for Scheduled Cesarean Deliveries (PERUSE)

Perioperative Use of Continuous Glucose Monitoring for Scheduled Cesarean Deliveries (PERUSE): A Pilot Study

This prospective pilot study is exploratory in nature and is designed to evaluate the validity of continuous glucose monitor (CGM) use for perioperative glucose surveillance during scheduled Cesarean delivery for nondiabetic patients. Primary objective is characterization of perioperative glucose trends during elective Cesarean delivery in patients without diabetes and exploratory analyses will describe perioperative glucose patterns captured by CGM. Secondary objective is to examine rates of and associations with post-operative complications, including surgical site infections.
