呼吸重症监护病房中长期机械通气患者的死亡危险因素分析

Risk Factors of Mortality Among Patients with Chronic Mechanical Ventilation in Respiratory Intensive Care Unit

目的探讨呼吸重症监护病房中长期机械通气患者的死亡危险因素。方法所选研究对象为2014年10月~2016年10月本院呼吸重症监护病房收治的长期机械通气患者62例。患者均采用回顾性分析的方法,调查一般资料。将62例患者按照生存情况,分为研究组(死亡,n=28)与对照组(生存,n=34)。对比两组临床资料,分析死亡危险因素。结果两组疾病类型、年龄≥60岁、机械通气时间≥3d、医院获得性肺炎所占比例对比,结果有统计学意义(P<0.05);研究组气管切开时间、血清白蛋白水平对比,结果有统计学意义(P<0.05)。结论高龄、严重肺炎、肺癌、血清白蛋白水平降低、机械通气时间及气管切开时间过长等是导致呼吸重症监护病房长期机械通气患者死亡的危险因素,需引起高度关注。

Objective Objective to investigate the risk factors of death in patients with chronic mechanical ventilation in respiratory intensive care unit（ICU）. Methods The subjects were chronic mechanical ventilation patients in the respiratory intensive care unit（-2016） in October 2014 October, including 62 cases. Retrospective analysis was used in 62 patients to investigate the general data. The 62 patients were divided into study group（death, n=28） and control group（survival, n=34） according to survival. The risk factors of death were analyzed by comparing the clinical data of the two groups. Results The proportion between pneumonia in two groups in the type of disease and age more than 60 years old, mechanical ventilation time, hospital acquired more than 3D, the results were statistically significant（P 〈 0.05）;The comparison of the time of tracheotomy and the level of serum albumin in the study group was statistically significant（P 〈 0.05）. Conclusion Elderly, severe pneumonia, cancer, low serum albumin level, long mechanical ventilation time and long tracheotomy time are the risk factors for the death of patients with long-term mechanical ventilation in respiratory intensive care unit.
