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.
