摘要
目的 :探讨麻醉前后QT离散度 (QTd)的变化及其临床意义。方法 :检测并计算出 5 5例手术病人麻醉前后的QT、QTc离散度 ,其中 12例为全身麻醉 ,4 3例为连硬麻醉。结果 :麻醉后病人的QTd、QTcd大于麻醉前 ,差异非常显著 (P <0 .0 1) ,全身麻醉后QTd、QTcd增大较连硬麻醉后更为明显 (P分别 <0 .0 5和 <0 .0 1)。结论 :麻醉可增大心室肌的复极离散度 ,可能与麻醉过程中心律失常的发生率增加相关 ,麻醉过程中应加强心脏监护 ,确保麻醉安全。
Objective: To investigate the changes of QT dispersion(QTd) before and after anaesthesia and the clinical effect. Methods: QTd and QTcd were measured and calculated before and after anaesthesia in 55 patients. Among these patients, 12 patients were taken total anaesthesia, 43 patients were taken maintenance epidur al block anaesthesia. Results: The QTd and QTcd were greater after anaesthesia tha n before. The difference was significant(P<0.01). The increase of QTd and QTcd after total anaesthesia was greater than after maintanance epid ural block anaesthesia. Conclusion: Anaesthesia may increase the repolarized dispersio n in ventricular muscle. Anaesthesia may be related with the increase of rate of arrhythmias so more attention should be paid to the heart when anaesthesia.
