老年患者术中连续心电监测201例分析

分析连续201例60岁以上老年麻醉手术期间连续心电监测的结果。术前常规心电图检查异常心电检出率33.8％,心律失常21.4％,麻醉手术期间异常心电检出率51.2％,心律失常40.3％。术前心电无异常术中严重心律失常发生率(3％)明显低于术前有异常者(10.3％)。术前室性早搏者,术中易诱发严重心律失常,为一危险因素。避免术中大出血及硬膜外麻醉药注入过量所致低血压,尽可能平稳诱导是预防严重心律失常的重要措施。推荐老年患者常规作术中连续心电监测。

CONTINUOUS ELECTRICAL CARDIOGRAPHY DURING OPERATION: Analysis of 201 consecutive aged cases

Continuous ECG monitoring during operation was studied in 201 consecutive cases of aged subjects over 60. Before operation the detection rates of abnormal ECG and arrythemia were 33.8% and 21.4% respectively; those during operation were 51.2% and 40.3% respectively. Serious arrythemia during operaion was found in 3% of those whose preoperative ECG was normal, with its incidence significantly lower than that(10.3%) of those whose ECG was abnormal before operation. preoperative ventricular extrasystole is a risk factor in aged subjects. To prevent serious arrythemia, hypotension following huge hemorrage and overinfusion of anesthetic drugs into epidural space should be avoided and smooth induction practised as far as possible. Continuous ECG monitoring during operation is reco mmended in all old subects.
