老年重症肺炎患者机械通气后短期预后的相关影响因素分析

目的：探讨分析该疾病患者短期预后的相关影响因素。方法：对120例老年重症肺炎机械通气患者的临床资料进行回顾性分析，采用Logistic回归分析法，对老年重症肺炎患者的机械通气后的病死率与并发症的相关因素进行分析。结果：病死率为29．17％，经回归分析后，病死率与心力衰竭、电解质紊乱与酸碱失衡、肝功能衰竭以及呼吸衰竭等因素有关（P〈0．05）；而与循环衰竭、胃肠损害（消化道出血异常）以及气胸等因素无关（P〉0．05）；影响患者短期预后的独立预测因素包括：高急性生理与慢性健康评分（APACHEII）、高急性生理学评分（APS）、低格拉斯哥昏迷（GCS）评分以及低白蛋白水平。结论：老年重症肺炎患者机械通气后，能够引起心力衰竭等症状，影响患者短期预后情况的重要因素。

Related Factors Analysis on Short-term Prognosis after Mechanical Ventilation in Elderly Patients with Severe Pneumonia

Objective： To analyze the related influencing factors of the short-term prognosis in patients with the disease. Methods： 120 cases of senile severe pneumonia patients with mechanical ventilation were retrospectively analyzed, mortality and complications of elderly patients with severe pneumonia after mechanical ventilation were analyzed using used logistic regression analysis. Results： Mortality was 29.17% after regression analysis, it was related to the case fatality rate and heart failure, electrolyte imbalance and acid-base imbalance, liver failure, respiratory failure and other factors （P〈0.05）; It was related to circulatory collapse, gastrointestinal damage （abnormal gastrointestinal bleeding）, pneumothorax, and other factors （P〉0.05）; Independent predictor of short-term prognosis in patients included： high acute physiology and chronic health evaluation （APACHE II ） acute physiology score （APS）, high, low Glasgow coma score （GCS）, and lower albumin levels. Conclusion： Mechanical ventilation used in elderly patients with severe pneumonia can cause heart failure and other symptom, and is one of the important factors influencing the short-term prognosis.
