| Objective To observe the perioperative analgesic effect of transcutaneous electrical stimulation of acupoints on burn debridement patients. Methods Using the random number table method, 80 burn patients with elective wound debridement under general anesthesia for the first time at the First Affiliated Hospital of Shihezi University between January and August 2024 were selected and randomized into two groups: the experimental group and the control group, with 40 cases in each group. In the experimental group, transcutaneous electrical stimulation of acupoints was performed 30 min before induction of anaesthesia until the end of the operation. While the control group received false stimulation. The analgesic effect within 48 hours after surgery, intraoperative anaesthetic drug dosage and the occurrence of postoperative adverse reactions within 24 hours after surgery were compared between the two groups. Results Postoperative pain scores tended to increase and then decrease in both groups, with the highest pain scores at 12h postoperatively and the lowest pain scores at 48 h postoperatively. The pain scores of the experimental group at 6 h, 12 h, 24 h postoperatively were lower than those of the control group（P ＜0.05）, but the differences in pain scores at 48 h postoperatively between the two groups were not statistically significant（P＞0.05）. Compared with the control group, the number of analgesic pump presses within 24 hours after surgery in the experimental group was reduced（P ＜0.05）, but there were no significant differences in the use of remedial analgesic drugs and satisfaction with postoperative analgesia between the two groups（P＞0.05）. The intraoperative remifentanil dosage of the experimental group was lower than that in the control group（P ＜ 0.05）, and there was no statistically significant difference in the comparison of propofol dosage（P＞ 0.05）. The incidence of nausea and vomiting and constipation in the experimental group was lower than that of the control group in the postoperative period of 24 h（P ＜ 0.05）, while the difference in the incidence of drowsiness and dizziness was not statistically significant when comparing between two groups（P ＞ 0.05）. Conclusion Transcutaneous electrical stimulation of acupoints applied to burn patients during debridement can safely and effectively relieve patients' early postoperative pain, reduce the use of perioperative analgesic drugs, and reduce the occurrence of postoperative gastrointestinal adverse reactions. |
