Effect of Preoperative Oral Energy Drinks Compared to Warming Matress on Body Temperature During Combined Spinal-epidural Anesthesia for Elective Cesarean Delivery.
August 29, 2023 updated by: Yi Feng, MD, Peking University People's Hospital
Effect of Preoperative Oral Energy Drinks Compared to Warming Matress on Body Temperature During Combined Spinal-epidural Anesthesia for Elective Cesarean Delivery: a Randomised Non-inferiority Trial.
It is not known which is better for intraoperative temperature protection, warming matress or preoperative oral functional drinks in elective cesarean section.
We plan to conduct a non inferiority randomized trial to clarify this problem.
