Abstract:
Objective:To examine the effects of transcutaneous electrical acupoint stimulation(TEAS)on pain and rapid recovery in elderly patients undergoing thoracoscopic surgery.Methods:A total of 60 elderly patients undergoing thoracoscopic surgery were randomly divided into the TEAS group and the control group.Patients in the TEAS group received TEAS in bilateral acupoints of Hegu, Neiguan, Houxi and Zhigou at a frequency of 2/100 Hz for 30 min before anesthesia induction.The electrical stimulation intensity went from weak to strong, and gradually adjusted to the patient's maximum tolerance(10 to 15 mA)continuously for 30 min; TEAS continued during intraoperative anesthesia with a stimulation intensity of 30 mA and a frequency of 2/100 Hz until the end of surgery.Patients in the control group were given electrode pads at the same acupoints without electrical stimulation.Results:Compared with the control group, patients in the TEAS group were associated with significantly decreased doses of Sufentanil[(57.93±5.54)μg vs (44.30±4.03 )μg, t=-10.903, P=0.000)], Remifentanil[(1.56±0.26)μg vs (1.08±0.18)μg, t=-8.3043, P=0.000)], Propofol[(763.23±62.04)mg vs (559.20±46.44) mg, t=-14.420, P=0.000)]and Dexmedetomidine[(545.07±53.36) vs (301.67±43.27) μg, t=-19.405, P=0.000)], reduced frequency of analgesic pump pressing(9.9±2.0 vs 2.9±1.3, t=-10.903, P=0.000), decreased VAS scores 24 h(3.53±1.07 vs 1.90±0.66, t=-7.090, P=0.000)and 48 h(1.37±0.61 vs 0.93±0.37, t=-4.660, P=0.000)postoperatively.Time to regaining consciousness, extubation and detachment were also markedly shortened in the TEAS group.In addition, time to postoperative feeding and time to postoperative ambulation were also reduced.Postoperative hospitalization days( P<0.05)and anesthesia cost( P<0.01)both significantly decreased in the TEAS group compared with those in the control group.Patients in the TEAS group had lower rates of nausea, vomiting, decreased oxygen saturation, dyspnea, dizziness, agitation and lethargy, and increased heart rate and decreased mean arterial pressure after the opening of the pleura(H1)compared with those in the control group(all P<0.05). Bispectral indexes were maintained between 40 and 60 after anesthesia in both groups(all P<0.01). Conclusions:TEAS-assisted anesthesia can effectively alleviate pain in elderly patients undergoing thoracoscopic surgery and promote rapid recovery after operation.
