ICU手术患者多重耐药菌感染危险因素分析

ANALYSIS ON RISK FACTORS OF MULTI-RESISTANT COLONIZATION INFECTION IN ICU SURGICAL PATIENTS

目的了解重症监护室(ICU)手术患者多重耐药菌(MDROS)感染现状及危险因素,为预防与控制MDROs感染提供参考依据。方法通过回顾性调查和目标性监测,对某医院ICU手术患者MDROs的感染情况进行监测,分析相关危险因素。结果该医院ICU共收治患者5 081例,包括手术患者859例和非手术患者4 222例。手术患者中发生MDROs感染268例,感染率31.20%;非手术患者中发生MDROs感染1 069例,感染率25.32%。MDROs感染与神经外科、胸外科、骨科等科室的手术及APACHEⅡ评分分值高(≥21分)有密切关系,构成MDROs感染的主要危险因素。结论 ICU手术患者MDROs感染率明显高于非手术患者,应将高危科室手术患者作为MDROs感染重点防控对象,采取必要的预防控制措施。

Objective To know the multi -resistant bacteria （MDROs） colonization infection and risk factors in ICU surgical patients and provide reference for preventing and controlling MDROs colonization infection. Methods Retrospective investigation and objective monitoring were used to investigate MDROs colonization infection and risk factors in ICU surgical patients. Results 5 081 patient were hospitalized in ICU, including 4 222 non - surgical patients and 859 surgical patients. The MDROs colonization infection rate of ICU surgical patients was 31.20% （268/859）, significantly higher than that of non - surgical patients （25.32%, 1069/4222,P 〈 0. 01 ）, and it was associated with emergency surgery, neurosurgery surgery, thoracic surgery, orthopedics surgery and APACHE Ⅱ score over 21 points, which were risk factors for MDROs colonization infection. Conclusion The MDROs colonization infection rate of ICU surgical patients was higher than non -surgical patients. It is necessary to take measures to prevent and control MDROs colonization infection for ICU surgical patients.
