Official title
The Application of Butorphanol in Postoperative Analgesia Management After Cesarean Section: A Retrospective Cohort Study
Overview
This study explored the association between postoperative functional recovery and the formula of analgesic pumps as well as other related factors (such as age, intraoperative blood loss, operation duration, etc.) by retrospectively analyzing the clinical data of patients undergoing cesarean section in the main campus and branches of Sichuan Provincial People's Hospital from September 2024 to June 2025. The value of this study lies in: 1) providing a basis for optimizing the postoperative analgesia plan after cesarean section. 2) To provide references for the formulation of personalized analgesia strategies in clinical practice, improve the postoperative recovery quality of patients, promote the concept of enhanced recovery after surgery, and reduce the medical burden.
