Abstract：Objective:To observe the effect of percutaneous acupoints electrical stimulation on the prevention of postoperative nausea and vomiting after gyneco-logical laparoscopic surgery unser the guidance of the theory of midnight-midday ebb flow.Methods:A total of 96 patients scheduled for gynecological laparoscopic surgery under general anesthesia were divided into a control group and an observation group,with 48 cases in each group,according to the random number table method.Both groups of patients received conventional anesthesia induction and intraoperative maintenance.The observation group,in combination with the midnight-midday ebb flow method,received percutaneou acupoints electrical stimulation treatment for 30 minutes before anesthesia induction and during the recovery period in the recovery room after surgery.The control group only had electrode patches attached and was not given electrical stimulation.The incidence of postoperative nausea and vomiting,the severity of nausea and vomiting[assessed by Visual Analogue Scale(VAS)],the levels of serum motilin(MTL)and 5-hydroxytryptamine(5-HT),and the incidence of other adverse reactions were compared between the two groups.Results:The incidences of nausea and vomiting within 24 hours after surgery in the observation group were 6.25％and 2.08％respectively,which were lower than 20.83％and 14.58％in the control group(P＜0.05).Within 48 hours after surgery,the total incidence of postoperative nausea and vomiting in the observation group was 10.42％and 4.17％respectively,which were lower than 27.08％and 16.67％in the control group(P＜0.05).At 24 hours and 48 hours after surgery,the VAS scores of the degree of nausea and vomiting in the observation group were lower than those in the control group(P＜0.05).At 12 hours after surgery,the levels of MTL in the serum of both groups of patients were higher than those before surgery,while the levels of 5-HT were lower than those before surgery(P＜0.05),and the levels of MTL and 5-HT in the observation group were lower than those in the control group(P＜0.05).The incidence of other adverse reactions was 6.25％in the observation group and 16.67％in the control group.There was no statistically significant difference between the two groups(P＞0.05).Conclusions:Percutaneous acupoints electrical stimulation can reduce the incidence of postoperative nausea and vomiting after gynecological laparoscopic surgery and alleviate the degree of nausea and vomiting unser the guidance of the theory of midnight-midday ebb flow.The mechanism may be related to preventing the increase of MTL and promoting the decrease of 5-HT,without increasing the risk of adverse reactions.
