A randomized controlled study of Hegu acupoint injection combined with auricular acupoint implantation for the prevention of intravenous analgesia PONV in abdominal surgery
Objective To observe the effect of Hegu acupoint injection of Vitamin B6 combined with auricular acupoint implantation on the prevention of nausea and vomiting(PONV)after intravenous analgesia after laparoscopic surgery.Methods A total of 100 patients with intravenous analgesia underwent laparoscopic surgery were randomly divided into study group and control group,with 50 cases each.Control group received totanisetron and dexamethasone to prevent PONV,while study group received Hegu acupoint injection of Vitamin B6 combined with auricular acupoint implantation.The incidence of nausea and vomiting at 0～2 h,2～6 h,and 6～24 h after surgery was compared;the scores of Visual Analogue Scale(VAS)at 2 h,6 h and 24 h after surgery were recorded and compared;the recovery time of gastrointestinal function,the severity of PONV symptoms within 72 h after surgery,the plasma concentrations of 5-hydroxytryptamine(5-HT)and dopamine in the immediately postoperative and 24 h in the two groups were compared.Results The incidence of nausea and vomiting in study group was lower than that in control group at 0～2 h,2～6 h and 6～24 h after surgery(P＜0.05);at 2 h,6 h and 24 h after surgery,the VAS scores in study group were lower than those in control group(P＜0.05);the recovery time of gastrointestinal function(bowel sounds,first flatus and defecation)in study group was lower than that in control group(P＜0.05);the degree of PONV symptoms in study group was milder than that in control group within 72 h after operation(P＜0.05);the plasma 5-HT and dopamine con-centrations in both groups were lower than those before operation 24 h after operation,and were lower in study group than those in control group(P＜0.05).Conclusion Hegu acupoint injection of Vitamin B6 combined with auricular acupoint implantation can prevent the occurrence of intravenous analgesia PONV in gynecological laparoscopic surgery,reduce the severity of PONV,release pain,restore gastrointestinal function,and reduce the levels of plasma neurotransmitters 5-HT and dopamine.
