Effect Of Percutaneous Acupoint Electrical Stimulation On Awakening Time Of Patients Undergoing Spinal Surgery Under General Anesthesia

Objective:Spinal surgery is more common in orthopedic clinic,which is about 5%to 6%.The trauma of the operation is great,the anatomical structure of the spine is complex,and the patients are prone to lung injuries such as prone position,impaired oxygenation function and pulmonary ventilation function,and are prone to stress reactions.affect the recovery time of the patient after general anesthesia and affect the patient’s postoperative recovery^[1,2].Percutaneous acupoint electrical stimulation（TEAS）is one of the commonly used TCM diagnosis and treatment techniques in clinical perioperative period.It combines the advantages of Chinese traditional acupuncture and percutaneous nerve electrical stimulation（TENS）,and has a wide range of adaptability in perioperative TCM diagnosis and treatment.The purpose of this study was to observe whether TEAS can improve the recovery time of patients undergoing spinal surgery under general anesthesia.Methods:In this randomized controlled study,93 patients undergoing spinal surgery were randomly divided into three groups:percutaneous acupoint electric stimulation group（group T）received TEAS（Zusanli,Sanyinjiao）20min before operation,TEAS（Neiguan,Quchi）after stopping sevoflurane for 30 minutes,and percutaneous non-acupoint electric stimulation group（group N）selected the above four acupoints to open 2cm laterally,and the stimulation time was the same as above.The control group（group C）was blank control group with31 cases in each group.The general data,eye opening time,extubation time,PACU stay time,postoperative VAS,Steward awakening score after extubation 15min,Ramsay sedation score and adverse reactions were compared among the three groups.Results:There was no significant difference in age,sex,BMI,preoperative Hb,duration of operation,mean blood pressure and heart rate before,during and after operation among the three groups.The eye opening time,extubation time and PACU stay time in group T were significantly shorter than those in the other two groups（P<0.05）.The scores of VAS,Steward awakening and Ramsay sedation after extubation in group T were better than those in the other two groups,and the difference was statistically significant.No complications or serious adverse reactions such as pulse oxygen saturation<90,larynx and airway spasm occurred in the three groups during the perioperative period.Conclusion:Applying TEAS at Zusanli,Sanyinjiao,Neiguan and Quchi points to patients undergoing spinal surgery under general anesthesia can shorten the recovery time after operation,reduce postoperative pain and improve the quality of recovery.TEAS is of good significance to the recovery time and quality of patients after general anesthesia.
