目的了解小儿ICU医院感染发病特点及规律。方法采用目标性监测的方法,前瞻性地研究2009年4月-2010年3月ICU患儿医院感染发病情况,用患者平均病情严重程度(ASIS)调整医院感染发生率,并对侵入性操作相关感染进行分析。结果 883例住院患儿中,发生医院感染103例次,例次感染率为11.66%,患者日例次感染率为15.30‰,经ASIS调整后患者日医院感染率为4.15‰;3种侵入性操作相关性感染日感染率分别为:呼吸机相关性肺炎49.44‰、留置导尿管相关性泌尿道感染2.41‰、动静脉插管相关性血液感染0.99‰。结论小儿ICU医院感染发生率较高,与应用各种导管相关,以呼吸机相关性肺炎为主;应重视目标性监测,加强对侵入性操作的管理与干预。
Objective To understand the characteristics and rules of pediatric ICU hospital infection. Methods By means of targeted monitoring, the incidence of nosocomial infections in children with ICU from April 2009 to March 2010 was prospectively studied. The incidence of nosocomial infections was adjusted with the average severity of illness (ASIS) of the patients and was associated with invasive procedures Infection is analyzed. Results Of the 883 hospitalized children, 103 cases of nosocomial infection occurred, the rate of case-specific infection was 11.66%. The daily infection rate was 15.30 ‰. The hospital-acquired nosocomial infection rate was 4.15 ‰ after ASIS adjustment. Operation-related infection day infection rates were: ventilator-associated pneumonia 49.44 ‰, indwelling catheter-related urinary tract infection 2.41 ‰, arteriovenous cannulation-related blood infection 0.99 ‰. Conclusions The incidence of nosocomial infection in pediatric ICU is relatively high, which is related to the use of various catheters and mainly to ventilator-associated pneumonia. Targeted monitoring should be emphasized to improve the management and intervention of invasive procedures.
