老年大肠癌患者围手术期死亡因素分析

目的探讨老年大肠癌患者围手术期死亡的原因及其预防措施：方法对我院1997年1月至2007年10月收治的大肠癌患者术后死亡的病例资料48例进行回顾性分析，根据患者年龄分为老年组32例和非老年组16例，比较两组死亡原因的差异结果老年组32例患者中死于心血管合并症28例（87、50％），其中心力衰竭19例（58．38％），心肌梗死5例（15．63％），恶性心律失常4例（12．50％）；死于肺部合并症2例（6．25％）；死于严重感染2例（6、25％）；而非老年组16例死于心血管合并症2例（12．50％），均为心肌梗死；死于肺部合并症3例（18．75％），死于严重感染8例（50．00％），死于麻醉意外2例（12．50％）；1例死亡因素不明。两组死亡因素具有显著不同，差异具有统计学意义（P〈0．05）。结论老年大肠癌患者围手术期死亡的主要原因为心血管合并症，熟悉老年人的病理生理特点、充分的术前准备、适当的手术时机与手术方式、完善的麻醉及心肺功能监测是减少并发症的有效方法。

Death factor analysis of aged patients with cancer of colon before and after operation

Objective To explore the death cause of the aged patients with cancer of colon during the period of operation and the precautions.
