Objective: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on the recovery of patients undergoing gastrointestinal surgery under general anesthesia.
Methods: Sixty patients (ASA Ⅱ-Ⅲ) selected for scheduled gastrointestinal surgery were randomly divided into control group and TEAS group (n=30 cases per group). Patients in the two groups received general anesthesia, and those of the TEAS group also received TEAS for 30 min (8-12 mA) immediately after surgery. The changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) before anesthesia, before acupoint stimulation, before extubation, immediately after extubation, 10 and 30 min after extubation were recorded. The recovery time of spontaneous breathing, extubation time, VAS scores and Bruggman comfort scale (BCS) scores at the time of discharging from postanesthesia care unit (PACU) were recorded.
Results: Compared with the control group, the recovery time of spontaneous breathing and extubation time were significantly shorter （P<0.05）, the VAS score was significantly lower (P<0.05), and the BCS score significantly increased in the TEAS group (P<0.05). There were no significant differences between two groups in the levels of SBP, DBP and HR at each time point (P>0.05).
Conclusion: TEAS can accelerate the gastrointestinal surgery patients' recovery from general anesthesia, enhance the postoperative analgesic effect, improve patients' discomfort, has less adverse reactions, and is thus conducive to promote the postoperative rehabilitation.
目的：观察经皮穴位电刺激(TEAS)对全麻胃肠外科手术患者术后麻醉复苏的影响。方法：选择择期拟行胃肠手术的患者60例，以随机数字表法分为对照组和TEAS组，每组30例。两组患者均采用静吸复合全身麻醉，对照组仅给予基础治疗；TEAS组除了给予基础治疗，术后即于双侧足三里、内关给予TEAS，持续30 min。比较两组患者在麻醉前、穴位刺激前、拔管前、拔管后即刻、拔管后10 min和拔管后30 min时的收缩压(SBP)、舒张压(DBP)、心率(HR)的变化，记录比较两组患者术毕自主呼吸恢复时间、拔管时间、出麻醉后监测治疗室(PACU)时疼痛视觉模拟量表(VAS)评分及舒适度行为量表(BCS)评分情况。结果：与对照组比较，TEAS组术后麻醉复苏期自主呼吸恢复时间及拔管时间缩短(P<0.05)，出PACU时VAS评分降低(P<0.05)，麻醉复苏期BCS评分升高(P<0.05)。两组各时点SBP、DBP、HR差异均无统计学意义(P＞0.05)。结论：经皮穴位电刺激可以加快胃肠外科全麻手术患者麻醉复苏，增强术后镇痛效果，提高患者舒适度且不良反应少，有利于促进患者术后康复。.
