目的探讨ICU机械通气相关性肺炎发病的危险因素。方法回顾分析187例患者的临床资料。结果抗生素可用种类>2种、低蛋白血症、重复插管、使用H2受体拮抗剂>5d、机械通气>5d、中心静脉置管>5d等和机械通气相关肺炎的发生有统计学上意义(P<0.05)。结论机械通气相关肺炎的发生使呼吸ICU病房中患者的死亡率增加,注意抗生素可用种类>2种、机械通气>5d、重复插管、低蛋白血症等方面对治疗效果的影响,可以很好的预防机械通气相关肺炎的发生。
Objective To investigate the risk factors of ICU mechanical ventilation-related pneumonia. Methods The clinical data of 187 patients were retrospectively analyzed. Results The available antibiotics were> 2 kinds, hypoproteinemia, repeated intubation, H2 receptor antagonist> 5 days, mechanical ventilation> 5 days, central venous catheter> 5 days and mechanical ventilation-related pneumonia were statistically significant (P <0.05). Conclusions The occurrence of mechanical ventilation-related pneumonitis may increase the mortality rate of patients in respiratory ICU wards. Attention should be paid to the effect of antibiotic available types> 2, mechanical ventilation> 5 days, repeated intubation and hypoproteinemia on the treatment effect Prevention of the occurrence of mechanical ventilation-related pneumonia.
