目的：比较腹腔镜胆囊切除术中老年人和年轻人patients.Methods：12名老年人和12名年轻人进行了研究。在所有患者中，在头高位进行腹膜内CO2吹入超过150分钟。结果：老年人CO2气腹后120 ~ 150 min，QT间期和QTc间期显著延长（P < 0. 05），心率校正QT间期（QJc）、QT离散度（QTD）和心率校正QT离散度（QTcD）显著延长（P < 0. 05）。CO2气腹期间两组患者的QTd和QTcD均显著增加。这些都是显着大于在年轻患者从120至150分钟后CO2 insufflation.Conclusion：较长的CO2吹入时间与头高位倾斜与QT间期和QTD在老年患者的延长。这些发现的临床意义仍有待确定。
Purpose: To compare the influence of a longer duration of intraperitoneal CO2 insufflation with head-up tilt on electrocardiogram indices during laparoscopic cholecystectomy between elderly and younger patients.Methods: Twelve elderly and 12 younger patients were studied. In all patients, intraperitoneal CO2 insufflation was performed for more than 150 min in the head-up position. RR interval, QT interval, the rate-corrected QT (QJc) interval, QT dispersion (QTD) and the rate-corrected QTD (QTcD) were measured.Results: The QT interval and the QTc interval increased significantly from 120 to 150 min after CO2 insufflation in the elderly. The QTD and QTcD increased significantly during CO2 insufflation in both groups. Those were significantly greater in the elderly than in younger patients from 120 to 150 min after CO2 insufflation.Conclusion: Longer duration of CO2 insufflation with head-up tilt is associated with a prolongation of the QT interval and the QTD in elderly patients. The clinical significance of these findings remains to be determined.
