ICU病房患者医院感染的调查及危险因素分析

A STUDY ON HOSPITAL ACQUIRED INFECTION OF PATIENTS IN ICU.

目的 :调查分析外科 ICU病房医院感染情况和危险因素。方法 :查阅 2 0 0 0～ 2 0 0 1年我院外科 ICU病房收治的 6 2 0例患者的临床资料 ,对医院感染各项危险因素进行单因素分析。结果 :ICU病房医院感染率为 14 .35 % ,感染部位依次是上呼吸道、胃肠道、泌尿、皮肤及其他。病菌以 G- 菌为主 ,不动杆菌最常见 (19.4 8% ) ,G+ 菌比例逐渐增高。停留时间长、同室人数多、应用皮质激素、呼吸机使用、留置导管、术后拔管时间晚、滥用抗生素等都是外科 ICU病房医院感染的危险因素。结论

Objective:To investigate the infection condition and risk factors of the surgical ICU patients.Methods:The clinical data of 620 ICU surgical patients were reviewed and analysed statistically.Results:The nosocomial infection rate was 14.35%.The most common site of infections was the upper respiratory tract,followed by gastric and urinary tract,skin and etc.The pathogenic bacteria mainly was G -,of which was dominated by Acinetobacter(19.48%) and G + proportion had the increasing trend.Conclusion:It shows that the high risk factors of infections in surgical ICU patients were time of staying,the number of patients together,and using of glucocorticoid,respirator, detaining conduct pipe,extubation occasio and broad-spectrum antibiotics abuse.
