Objective To investigate the causes of ICU in patients with ventilator-associated pneumonia after tumor resection . Methods In 278 patients with mechanical ventilation after tumor resection of tracheal intubation or tracheotomy ,culture of path-ogenic microorganisms on the incidence of ventilator-associated pneumonia patients ,and the patients with VAP were analyzed .Re-sults In 278 patients,34 patients with ventilator-associated pneumonia(VAP),VAP infection rate was 12.2%;cultivation of mi-crobial pathogens in 34 cases of VAP patients and its sampling specimens ,train a total of 69 pathogenic microorganisms including gram negative bacteria,48 strains(69.6%),gram positive bacteria and 12 strains(17.4%) and 9 strains of fungi(13%).The reason of ventilator associated pneumonia:ventilator management improper 35.3%,29.4%patients with respiratory tract obstruc-tion .Conclusion ICU patients with ventilator-associated pneumonia after tumor resection ,the main causes for ventilator manage-ment is inappropriate and patients with respiratory tract obstruction .%目的：探讨肿瘤术后患者ICU呼吸机相关性肺炎的发生原因。方法278例肿瘤术后行气管插管或者气管切开进行机械通气的患者，对发生呼吸机相关性肺炎的患者进行病原微生物的培养，并对患者发生呼吸机相关性肺炎的原因进行评价分析。结果278例患者中，有34例发生呼吸机相关性肺炎（VAP），VAP的感染率为12．2％；对发生VAP的34例患者取其标本进行病原微生物的培养，共培养出病原微生物69株，其中革兰氏阴性菌48株（69．6％），革兰氏阳性菌12株（17．4％）以及真菌9株（13．0％）。呼吸机相关性肺炎发生原因：呼吸机的管理不妥当35．3％，患者呼吸道不通畅29．4％。结论肿瘤术后患者ICU呼吸机相关性肺炎，发生的最主要原因为呼吸机的管理不妥当以及患者呼吸道不通畅。
