肿瘤外科患者呼吸机相关性肺炎发生危险因素分析

目的分析肿瘤外科患者呼吸机相关性肺炎(VAP)发生的危险因素。方法选取2017-10-2018-10间收治的88例机械通气超过48 h的肿瘤外科患者,对其临床资料进行回顾性分析。结果 88例患者中34例(38.64%)发生VAP,单因素分析显示,气管切开、胃肠内营养、ICU住院时间、机械通气时间、术前使用抗生素超过48 h等,是VAP发生的危险因素(P<0.05)。多因素分析显示,胃肠内营养是VAP发生的独立危险因素(P<0.05)。结论肿瘤外科患者VAP发生率较高,相关危险因素较多,胃肠内营养是主要的独立危险因素,应加强相关预防措施,降低其发生风险。

Analysis of risk factors of ventilator-associated pneumonia in tumor surgery patients

Objective To study the risk factors of ventilator-associated pneumonia in tumor surgery patients.Methods Totally 88 patients with tumor surgical mechanical ventilation for more than 48 hours were selected from October 2017 to October 2018. The risk factors of ventilator-associated pneumonia were summarized by retrospective analysis.Results Among the 88 patients, 34 patients(38.64%) developed ventilator-associated pneumonia. Univariate analysis showed that tracheotomy, enteral nutrition, ICU hospitalization time, mechanical ventilation time, preoperative use of antibiotics for more than 48 hours, are ventilator phase. Risk factors of related pneumonia(P<0.05). Multivariate analysis showed that gastrointestinal nutrition was an independent risk factor for ventilator-associated pneumonia(P<0.05).Conclusion Ventilator-associated pneumonia is more likely to occur in tumor surgery patients, and there are many related risk factors. Gastrointestinal nutrition is the main independent risk factor, so attention should be paid to it in clinical treatment and nursing.
