本研究采用计算机测量方法比较腹腔内CO2灌注与腹壁提升对腹腔镜胆囊切除术中RR间期、QT间期、校正率QT间期、QT离散度和校正率QTD的影响。将30例拟行腹腔镜胆囊切除术的患者随机分为2组：腹腔内CO2注入组（CO2组）和腹壁提升组（lift组）。监测12导联心电图以测量参数。两组患者的RR间期、QT间期和QTc间期在研究期间均无明显变化。CO，组的QTD和QTcD在CO2充气过程中显著升高，且显著高于lift组。有统计学意义的QTD和QTcD增加与心律失常和心脏事件的风险增加有关，发生在CO2充气期间，CO2组的QTD和QTcD显著高于lift组。
This study compared the effect of intraperitoneal CO2 insufflation with abdominal wall lift on RR interval, QT interval, the rate-corrected QT (QTc) interval, QT dispersion (QTD), and the rate-corrected QTD (QTcD) using computerized measurement during laparoscopic cholecystectomy. Thirty patients scheduled for laparoscopic cholecystectomy were randomly assigned to 2 groups: intraperitoneal CO2 insufflation (CO2 group) or abdominal wall lift (lift group). A 12-lead electrocardiogram was monitored to measure parameters. The RR interval, QT interval, and QTc interval did not change significantly during the study in both groups. The QTD and QTcD in the CO, group increased significantly during CO2 insufflation, and were significantly higher than those of the lift group. Statistically significant increases of QTD and QTcD, which are associated with an increased risk of arrhythmias and cardiac events, occur during CO2 insufflation, and QTD and QTcD in the CO2 group were significantly higher than those of the lift group.
