[Transcutaneous electrical acupoint stimulation reduces perioperative arrhythmia risk and improves recovery quality in laparoscopic cholecystectomy: mechanisms involving suppression of repolarization abnormalities induced by CO<sub>2</sub> pneumoperitoneum].
摘要
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: 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: <0.05). CONCLUSIONS: pneumoperitoneum in patients undergoing LC. Besides, it significantly shortens postoperative emergence time and alleviates pain at early emergence stage, demonstrating a potential clinical value.
