侵入性麻醉操作对发生医院感染的影响

Impact of invasive anesthetic operation on incidence of nosocomial infections

目的探讨侵入性麻醉操作对发生医院感染的影响。方法选取2009年2月-2011年2月因各种疾病行手术治疗患者1750例,将侵入性麻醉方式850例患者分为观察组;900例非侵入性麻醉方式患者为对照组,回顾性分析两组医院感染发生情况,并进行统计分析。结果观察组医院感染率为10.6%,其中呼吸道感染率为9.5%,包括上呼吸道占5.4%、下呼吸道占4.1%,明显高于对照组,经统计分析,差异有统计学意义(P<0.05)。结论侵入性麻醉操作能够增加医院感染的发生率,其中以呼吸道感染为多发,建议临床治疗中注意预防。

OBJECTIVE To explore the impact of invasive anesthetic operation on the incidence of nosocomial infections. METHODS A total of 1750 cases of patients with various diseases, who were treated in the hospital from Feb 2009 to Feb 2011, were enrolled in the study and were randomly divided into the observation group with 850 patients （invasive anesthesia） and the control group with 900 patients （non-invasive anesthesia）. The incidence of the nosocomial infections for the two groups was analyzed retrospectively, and the results were statistically analyzed. RESULTS In the observation group , the incidence rate of nosocomial infections was 10.6 %, and the incidence of respiratory tract infections was 9.5 %, among which the patients with upper respiratory tract infections accounted for 5.4 %, the patients with lower respiratory tract infections 4.1 %, significantly higher than that of the control group, the statistical analysis showed that the difference was statistically significant （P〈0.05）. CONCLUSION The invasive anesthetic operation can increase the incidence of nosocomial infections among which the respiratory tract infection is the most prevalent, and it is necessary to focus on the prevention during the clinical treatment.
