Abstract:

Objective To evaluate the therapeutic efficacy and safety of perioperative electroacupuncture on postoperative abdominal pain in patients undergoing general anesthesia laparoscopic surgery. Methods A total of 130 patients undergoing general anesthesia laparoscopic surgery were randomly divided into control group and experimental group. The control group received surgery under endotracheal intubation general anesthesia， while the experimental group received one session of electroacupuncture analgesia before and during anesthesia in addition to routine general anesthesia. The preoperative and postoperative pain Numerical rating scale （NRS）， Pain Catastrophizing Scale （PCS）， Bruggrmann comfort scale （BCS）， heart rate， and blood pressure were compared between the two groups. The occurrence of common adverse reactions after surgery， such as significant itching， rash， nausea， and vomiting， was observed. Results No significant difference in activity NRS score was found between the two groups after surgery （P = 0.618）. Compared with the control group， the experimental group had lower resting NRS score ［（2.05 ± 1.138），（1.62 ± 0.878）， P = 0.017］， lower PCS score ［（20.57 ± 8.538），（17.09 ± 8.291）， P = 0.020］， and higher BCS score after surgery ［（2.08 ± 1.035），（2.55 ± 1.046）， P = 0.010］， and decreased heart rate ［（76.17 ± 14.500），（70.85 ± 11.990）， P = 0.024］. There was no significant difference in systolic blood pressure between the two groups 12 and 24 hours after surgery （P > 0.05）. A decrease in systolic blood pressure 24 hours after surgery was found in the experimental group when compared to that before surgery ［（125.6 ± 15.725）， （123.60 ± 16.781）， P = 0.040］. Conclusion Perioperative electroacupuncture stimulation can relieve postoperative abdominal pain， reduce heart rate and blood pressure， but does not increase the occurrence of adverse reactions.
