经皮穴位电刺激对双腔支气管插管患者术后咽喉痛的影响

Effect of transcutaneous electrical acupoint stimulation on postoperative sore throat in patients un⁃dergoing double⁃lumen endobronchial intubation

目的探讨经皮穴位电刺激(TEAS)对双腔支气管插管全麻患者术后咽喉痛(POST)的影响。方法选择2021年10月至2022年3月择期行双腔支气管插管全麻的手术患者103例,男45例,女58例,年龄18~64岁,BMI 18~28 kg/m^(2),ASAⅠ—Ⅲ级。采用随机数字表法将患者分为两组:TEAS组(n=51)和对照组(n=52)。TEAS组于麻醉诱导前30 min在天突穴和双侧合谷穴行TEAS,至患者送至恢复室前停止;对照组放置电极片于相同穴位,但不进行电刺激。记录Mallampati分级、气管插管尝试次数、按压环状软骨、插管时阻力和双腔支气管导管(DLT)留置时间。记录拔管后1、6、24 h POST发生情况及严重程度、咽喉VAS疼痛评分和声嘶发生情况。结果与对照组比较,TEAS组拔管后1、6、24 h POST总发生率、POST 1级发生率和咽喉VAS疼痛评分明显降低(P<0.05),拔管后6 h POST 2级发生率明显降低(P<0.05)。两组拔管后1、6、24 h声嘶发生率差异均无统计学意义。结论经皮穴位电刺激天突穴和双侧合谷穴可明显降低双腔支气管插管患者术后咽喉痛的发生率、严重程度和咽喉VAS疼痛评分。

Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on postoperative sore throat(POST)in patients undergoing double⁃lumen bronchial intubation based on general anesthesia.Methods A total of 103 patients,45 males and 58 females,aged 18-64 years,BMI 18-28 kg/m^(2),ASA physical statusⅠ-Ⅲ,who received selective operation of double⁃lumen bronchial intubation under general anesthesia were selected.The patients were divided into two groups using the random number table method:TEAS group(n=51)and control group(n=52).In the TEAS group,TEAS on Tiantu acupoint and bilateral Hegu acupoints started 30 minutes before anesthesia induction,and the stimulation lasted until the patients were sent to the recovery room.In the control group,electrodes were placed on the same acupoints without electrical stimulation.The Mallampati grade,number of tracheal intu⁃bation attempts,compression of cricoid cartilage,resistance during intubation,and double⁃lumen endobron⁃chial tube(DLT)retention time were recorded.The incidence and severity of POST,VAS pain scores of sore throat,and the incidence of hoarseness 1 hour,6,and 24 hours after extubation were recorded.Results Compared with the control group,the incidence of POST,the incidence of POST level 1,and VAS pain scores of sore throat were significantly decreased 1 hour,6,and 24 hours after extubation(P<0.05),the incidence of POST level 2 was significantly decreased 6 hours after extubation in the TEAS group(P<0.05).There were no significant differences in the situations related to tracheal intubation,and the inci⁃dence of hoarseness 1 hour,6,and 24 hours after extubation between the two groups.Conclusion The transcutaneous electrical acupoint stimulation on Tiantu acupoint and bilateral Hegu acupoints can signifi⁃cantly reduce the incidence and severity of postoperative sore throat,and VAS pain scores of sore throat in patients undergoing double⁃lumen bronchial intubation.
