目的探讨重症监护病房(ICU)合并医院感染影响因素及护理对策。方法选择重症监护病房460例患者作为研究对象,以医院感染患者为观察组,按照1∶1比例选择未合并医院感染患者作为对照组,比较两组可能影响医院感染因素差异。结果 460例患者中发生医院感染80例,感染率17.39%,包括呼吸道感染、泌尿系统感染、导管相关性感染,单因素检验结果显示,10个变量是医院感染的相关因素(P<0.05),logistic回归分析引起医院感染的危险因素为:年龄大、实施侵入性操作、APACHEⅡ评分高、预防应用抗菌药物,其OR值分别为3.29、3.04、2.94、2.45。结论重症监护病房医院感染发生率较高,是多种因素作用的结果,改善老年患者的自身状况、加强危重患者治疗、合理使用抗菌药物、严格无菌操作,可降低ICU医院感染率。
Objective To explore the influencing factors and nursing countermeasures of intensive care unit (ICU) with nosocomial infection. Methods 460 patients in intensive care unit were selected as the research object. Patients with nosocomial infection were selected as the observation group. The patients without nosocomial infection were selected as the control group according to the ratio of 1: 1. The differences between the two groups in the factors influencing nosocomial infection were compared. Results Among the 460 patients, nosocomial infection occurred in 80 cases, with an infection rate of 17.39%, including respiratory tract infection, urinary system infection and catheter-related infection. The results of single factor test showed that 10 variables were related to nosocomial infection (P <0.05) Logistic regression analysis of risk factors for nosocomial infections were older, invasive procedures, high APACHE II scores, and antimicrobial prophylaxis, with ORs of 3.29, 3.04, 2.94 and 2.45 respectively. Conclusion The incidence of nosocomial infections in intensive care unit is high, which is the result of many factors. Improving the condition of elderly patients, strengthening the treatment of critically ill patients, rational use of antimicrobial agents and strict aseptic technique can reduce the infection rate in ICU hospitals.
