外科加强治疗病房获得性真菌感染的分析

Analysis of the nosocomial fungal infections in surgical intensive care unit

目的探讨外科加强治疗病房 (SICU)内获得性真菌感染的流行病学特点及与感染相关的危险因素。方法回顾性分析 88例病原学检查阳性的危重症患者的临床资料。结果 88例患者中单纯细菌感染 5 0例 ,真菌感染 38例 (均为SICU内获得性真菌感染 ) ,两组住SICU时间分别为 (12± 8)d ,(2 0± 2 4 )d(P <0 0 5 )。获得性真菌感染的部位主要为呼吸道 (6 5 8% ) ,主要致病菌株为白色念珠菌 (4 7 4 % )。结论SICU内获得性真菌感染的常见感染部位是呼吸道 ,常见致病菌为白色念珠菌 ,住SICU的时间长短与获得性真菌感染的发生密切相关。

ObjectiveTo investigate the epidemiology and risk factors of nosocomial fungal infections in surgical intensive care unit.MethodsThe clinical data of 88 poor risk surgical patients with positive pathogenic results were retrospectively analyzed. ResultsFifty patients were complicated with simple bacterial infections and 38 patients suffered from nosocomial fungal infections. The SICU stay was longer in fungal infectious patients (20±24 vs 12±8 days; P<0.05).Respiratory tract was the main infection site(65.8%). The most commonly isolated species was Candida albicans (47.4%).ConclusionsThe most frequently nosocomial fungal infection site involved was respiratory tract, and Candida albicans was the most common pathogen. Length of SICU stay was in close relation with the occurrence of fungal infection.
