Effect Of Percutaneous Electrical Stimulation On Gastrointestinal Function After Knee Replacement

ObjectiveDuring the perioperative period,the recovery of gastrointestinal function in elderly patients after knee replacement was observed through percutaneous electrical stimulation at four acupoints(Zusanli,Sanyinjiao,Neiguan and Hegu),and the effectiveness,safety and adverse reactions of acupoint stimulation were discussed.methodsA total of 60 adult patients,aged 60-85 years,were randomly divided into two groups: acupoint stimulation group and non-acupoint stimulation group.Acupoint stimulation group: 30 minutes before anesthesia and 30 minutes after surgery,the two sides of the upper limbs(Neiguan,Hegu)and one side of the lower limbs(Zusanli,Sanyinjiao)were given percutaneous acupuncture point electrical stimulation.Non-acupoint stimulation group: patients were connected with electroacupuncture stimulator,but no stimulation was given.Intervention measures: a special person is responsible for the implementation of percutaneous acupoint electrical stimulation.Turn on the stimulator before the test,check the stimulator is in normal working state,locate the acupoints on the body surface,and paste the special transdermal electrode.The wire of the stimulator is connected with the electrode plate,and the intervention is carried out according to the stimulation mode,stimulation intensity and stimulation time.Outcome measures: Patients were followed up before surgery and on day 1,3and 7 after admission.The main indexes observed were the postoperative recovery level of gastrointestinal function and the incidence of postoperative gastrointestinal complications,including the first postoperative exhaust time,the first postoperative defecation time,the recovery time of intestinal sounds,and the incidence of postoperative nausea,vomiting and abdominal distension.At the same time,the plasma levels of motilin(MTL),COR(cortisol),ACTH(adrenocorticotropic hormone)and blood glucose were measured before and 1,3 and 7 days after surgery.Statistical data were analyzed using SPSS18.0 software.conclusionAcupoint stimulation can reduce postoperative stress hormone levels,promote postoperative defecation,bowel sounds and peristalsis recovery,reduce postoperative stress response,and reduce postoperative nausea,vomiting,abdominal distension and other common postoperative gastrointestinal complications.Percutaneous acupoint electrical stimulation can speed up the recovery of gastrointestinal function after surgery,and is beneficial to reduce the patients’ unpleasant feelings caused by gastrointestinal function discomfort.It has a broad prospect of clinical promotion and application.
