摘要 目的探讨结肠癌术后感染的危险因素及病原分布特点,为预防术后感染提供依据。方法回顾性分析浙江省长兴县人民医院2001年3月-2013年3月行结肠癌手术治疗的549例患者的临床资料,对相关因素进行单因素χ2检验和多因素Logistic回归模型分析,并分析术后感染患者病原菌分布状况。结果结肠癌术后感染发生率为12.20%(67/549),单因素分析显示合并糖尿病、白蛋白<35 g/L、手术时间≥3 h、术中输血患者术后感染率高(χ2=13.001、7.456、4.165和6.008,P=0.000、0.006、0.041、0.014)。进一步行多因素Logistic回归分析显示合并糖尿病(OR=2.578,P=0.017)、白蛋白<35 g/L(OR=1.635,P=0.009)、术中输血(OR=1.254,P=0.024)均与术后感染独立相关。病原菌检测共分离病原菌81株,革兰阴性菌占61.73%(50/81),革兰阳性菌占32.10%(26/81),其中大肠埃希菌为最多见的病原菌,占23.46%(19/81)。结论该院结肠癌术后感染发生率较高,革兰阴性菌是主要致病菌群。糖尿病、白蛋白<35g/L和术中输血是术后感染的主要危险因素。
