肺癌患者下呼吸道感染的现状及危险因素分析

目的探讨肺癌患者下呼吸道感染的现状及危险因素。方法选择2009年11月至2011年10月收治的肺癌患者110例，观察患者是否发生下呼吸道感染，分析患者性别、年龄、吸烟史、肺癌分期、住院时间、侵人性操作、抗生素应用是否为下呼吸道感染发生的危险因素。结果110例肺癌患者发生下呼吸道感染者71例，发生率为64．5％，以革兰阴性菌感染为主，其发生明显受到患者年龄、吸烟史、肺癌分期、住院时间、侵入性操作、抗生素应用的影响（P〈0．05）。结论肺癌患者的年龄、吸烟史、肺癌分期、住院时间、侵人性操作、抗生素应用均为发生下呼吸道感染的危险因素，临床工作中应该针对可干预的危险因素采取有效的预防措施，提高患者的生活质量。

Analysis of present situation and risk factors on the patients with lung cancer complicated with lower respiratory tract infection

Objective To analyze the present situation and risk factors on the patients with lung cancer complicated with lower respiratory tract infection.Methods From November 2009 to October 2011 in our hospital,110 cases of lung cancer were selected,observed whether or not developing lower respiratory tract infection,and analyzed patient’s gender,age,smoking history,lung cancer stage,duration of hospitalization,invasive procedures,antibiotic application whether the risk factors for lower respiratory tract infection.ResultsIn this 110 cases of lung cancer,71 cases with lower respiratory tract infection,the incidence rate was 64.5%,the main pathogens were Gram negative bacteria,its occurrence was related with the patient’s age,smoking history,lung cancer stage,duration of hospitalization,invasive procedures,antibiotic application(P<0.05).Conclusions Lung cancer patient’s age,smoking history,lung cancer stage,duration of hospitalization,invasive procedures,antibiotic application are the risk factors of lower respiratory tract infection,clinical workers should take effective preventive measures for intervention risk factors to improve the patient’s quality of life.
