Clinical Trial Of Acupoint-injecting Lappaconitine Improves Management Of Posthemorrhoidectomy Pain

PURPOSE: In an effort to achieve an ideal and effective postoperative analgesic method by applying Acupoint injection, a prospectice trial was conducted to investigate the postoperative analgesic effect of lappaconitine hydrobromide. METHOD: 44 patients with mix hemorrhoids were scheduled to perform hemorrhoidectomy, they were randomly divided into 3 groups: Yaoshu-point-injection group (n=15), Ashi-points-injection group (n=14), and controlled group (n=15). In Yaoshu-point-injection group, 2ml lappaconitine hydrobromide was injected into Yaoshu point after anesthesia in sacral canal ,and an Ashi-point injection when the procedure was finished. Ashi-points-injection group only take an injection into Ashi points when the procedure was over. The controlled group didn't treate with lappaconitine hydrobromide. The severity of postoperative pain and complications , side effects was observed respectively, pain scores was assessed by visual analogue pain scales (VAS).RESULT: Subjective pain response was lower in Acupoint-injection groups. The Yaoshu-point-injection group had less pain than Ashi-points-injection group at the day of surgery; however, this was at the expense of increased urinary retention. And the occurrence of edema at anal margin was lower in Acupoint-injection groups. We didn't observe that using lappaconitine hydrobromide may increase the side effects. CONCLUSION: â‘ postoperative pain after hemorrhoidectomy can be safely and effectively controlled by Acuepoint inject of lappaconitine hydrobromide â‘¡Using the Ashi-points-injection of lappaconitine hydrobromide after hemorrhoidectomy can reduce the pain for a longtime â‘¢Combined with Yaoshu-point-injection can enhance the anaesthetic effect at the day of surgeryâ‘£The edema at anal margin can be reduced by using of Ashi-points-injection of lappaconitine hydrobromide...
