ABSTRACT
OBJECTIVES: To investigate the effects of transcutaneous electrical acupoint stimulation (TEAS) as an auxiliary approach to anesthesia on perioperative surface electrocardiogram repolarization indices and emergence quality in patients undergoing laparoscopic cholecystectomy (LC).
METHODS: Sixty patients undergoing elective LC were randomly assigned to either a TEAS group (30 cases, 2 cases excluded) or a control group (30 cases, 2 cases excluded). In the TEAS group, the stimulation at bilateral Neiguan (PC6) and Waiguan (TE5) acupoints was initiated before anesthesia, with disperse-dense wave, at the frequency of 2 Hz/10 Hz and the intensity of 4 mA to 10 mA, maintained throughout the surgical procedure. Separately, at the preoperative baseline (t0), 1 min after anesthesia induction (t1), 1 min after CO pneumoperitoneum establishment (t2), 30 min after CO pneumoperitoneum (t3), and 10 min after operation (t4), the electrocardiographic workstation was used to measure the patients' QT interval dispersion (QTD), corrected QT interval dispersion (QTcD), QT interval (QT), corrected QT interval (QTc), low-frequency normalized value [LF(norm)], high-frequency normalized value [HF(norm)], and low-frequency/high-frequency ratio (LF/HF), as well as the mean arterial pressure (MAP) and heart rate (HR). Emergence time and visual analog scale (VAS) scores in 1, 6, and 24 h after emergence were recorded, respectively.
RESULTS: Compared with the indicators at t0, QTD was increased in the control group (t2, t3, t4) and the TEAS group (t2) (P<0.001, P<0.01, P<0.05);and QTcD was increased in the control group (t2, t3, t4) (P<0.001, P<0.01, P<0.05). In comparison with the control group, QTD and QTcD decreased in the TEAS group (t2, t3, t4) (P<0.001, P<0.05, P<0.01), HR was reduced in the TEAS group (t2, t3, P<0.05), and the emergence time was shorter in the TEAS group (P<0.01), and VAS score was lower in 1 h after emergence (P<0.05).
CONCLUSIONS: TEAS-assisted anesthesia effectively reduces the risk of arrhythmia during CO pneumoperitoneum in patients undergoing LC. Besides, it significantly shortens postoperative emergence time and alleviates pain at early emergence stage, demonstrating a potential clinical value.
