麻醉患者肺部感染临床特征分析

Clinical features of pulmonary infections in patients after anesthesia

目的分析麻醉患者肺部感染的临床特征,为防治肺部感染提供理论依据。方法回顾性分析2009年1月-2010年12月麻醉手术患者的临床资料。结果共调查1100例患者,其中89例发生肺部感染,感染率为8.09%;检出革兰阴性菌65株,占73.03%,革兰阳性菌24株,占26.97%;分布最多的为铜绿假单胞菌占24.72%、肺炎克雷伯菌占16.85%、金黄色葡萄球菌占15.73%;肺部感染与麻醉方式、手术持续时间和年龄有关,差异均有统计学意义(P<0.05)。结论麻醉患者肺部感染率较高,这与麻醉方式及多项围手术期操作有关。

OBJECTIVE To study the clinical features of pulmonary infections in patients after anesthesia so as to provide the theoretical basis for the prevention of pulmonary infections.METHODS The clinical data of 1100 patients who underwent anesthesia were respectively reviewed.RESULTS Of 1100 patients investigated,pulmonary infections occurred in 89 cases（8.09%）;there were 65（73.03%）strains of gram-negative bacteria and 24 strains（26.97%） of gram-positive bacteria isolated,the most common pathogens comprised Pseudomonas aeruginosa（24.72%）,Klebsiella pneumoniae（16.85%）,and Staphylococcus aureus（15.73%）;the pulmonary infections were related to the anesthesia approach,the duration of surgery as well as the age,the difference was statistically significantly（P〈0.05）.CONCLUSION The incidence of pulmonary infections is high in the patients after anesthesia,which is related to the anesthesia approach and other perioperative maneuver.
