经机械呼吸治疗的慢性阻塞性肺疾病(COPD)呼吸衰竭102例中死亡48例,病死率47.1％。入院时重要脏器功能损害数与预后有关,2个脏器损害者病死率34.1％,3个脏器受累者52.9％,4个或4个以上脏器损害者68.2％,三组间病死率差别有统计学意义(P<0.01)。而年龄、性别、病程、以往有无呼吸衰竭史或人工气道史。入院时血气、本次住院人工气道次数、人工气道留置时间等因素与预后均无关。机械呼吸中发生气胸8例,死亡6例,病死率75％,但与未发生气胸组相比,病死率的差别未达到无统计学意义。
Of the 102 cases of chronic obstructive pulmonary disease (COPD) respiratory failure treated by mechanical respiration, 48 died, with a mortality rate of 47.1%. On admission, the number of major organ dysfunction was related to the prognosis. The morbidity rate was 34.1% for 2 organ damage, 52.9% for 3 organs and 68.2% for those with 4 or more organs. Mortality rate among the three groups The difference was statistically significant (P <0.01). The age, gender, duration of the past with or without respiratory failure history or artificial airway history. Admission blood gas, the number of hospitalized artificial airway, artificial airway indwelling time and other factors have nothing to do with the prognosis. There were 8 cases of pneumothorax occurred in mechanical respiration, 6 cases died, the case fatality rate was 75%. However, the difference in case fatality rate did not reach to statistical significance compared with no pneumothorax group.
