Women with a preoperative PSQ 6 were randomly divided into a high pain-sensitive control group (HC group) and a high pain-sensitive observation group (HO group). After the surgery, patients received the pump butorphanol concentration was 3.5 μg·kg− 1·h− 1 in the LC and HC groups, 3.0 μg·kg− 1·h− 1 in the LO group and 4.0 μg·kg− 1·h− 1 in the HO group.To compare the analgesic effects of postoperative PCIA and postoperative recovery in women.Results: Wound pain and uterine contraction pain VAS scores at rest and activity were significantly lower in the LC group than in the LO group at 4 and 8 h postoperatively (P 0.05).Conclusion: Compared to the weight-based postoperative PCIA, the PSQ-based postoperative PCIA has better analgesic effects and can improve maternal satisfaction with postoperative analgesia.Keywords: pain sensitivity, butorphanol, cesarean section, operative analgesia
