胃肠道肿瘤术后真菌感染危险因素分析

目的探讨胃肠道肿瘤术后真菌感染的危险因素,为临床预防真菌感染提供理论依据。方法回顾性分析我院本专业组2006年1—6月间行胃肠道肿瘤手术患者116例的相关病史资料,对真菌感染的可能危险因素进行单因素和多因素lo- gistic回归分析。结果①116例中诊断为真菌感染的18例,共获46份培养阳性标本,真菌感染患者菌种以白念珠菌为主,占15/20,感染部位以肠道为主,占14/18;②胃肠道肿瘤手术后真菌感染与抗生素使用时间、术后禁食时间、低蛋白血症、术后高血糖、合并细菌感染有关,其中抗生素使用时间是独立相关因素(P＜0．05)。结论胃肠道肿瘤术后应规范使用抗生素、营养支持、适时开始肠内营养、控制血糖,从而有效预防真菌感染。

Analysis on the risk factors associated with fungal infection following operation of gastrointestinal neoplasm

Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.
