目的:探讨呼吸衰竭患者进入急诊抢救室的时间与其疾病预后的联系。方法:选取2013年1月至2014年1月因呼吸衰竭进入我院急诊抢救室的患者64例作为研究对象。结果:在工作时间进入我院急诊抢救室的患者有44例(68.75%)明显高于在休息时间进入我院急诊抢救室的患者20例(31.25%),且二者相比具有统计学差异(p<0.05);其中Ⅰ型呼吸衰竭患者有40例(62.5%)明显多于Ⅱ型呼吸衰竭患者24例(37.5%),且二者相比具有统计学差异(p<0.05)。影响死亡率的相关因素有:PaO2值(OR=1.08,95%置信区间0.94-1.24)、pH值(OR=1.42,95%,置信区间1.09-1.64)、PaCO2值(OR=0.95,95%,置信区间0.86-1.19)。和患者住院时间延长的相关因素有:吸烟史(OR=0.84,95%置信区间0.71-0.99)、年龄(OR=0.91,95%置信区间0.84-1.04)、血液中乳酸的含量(OR=1.09,95%置信区间0.90-1.32)。结论:呼吸衰竭患者的住院时间与死亡率和入急诊抢救室的时间无显著相关性。
Objective: To explore the relationship between the time when patients with respiratory failure enter the emergency room and their prognosis. Methods: From January 2013 to January 2014, 64 patients who entered the emergency room of our hospital due to respiratory failure were selected as the study objects. Results: Forty-four patients (68.75%) who entered emergency room during the working hours were significantly higher than those who entered emergency room during the rest time in 20 cases (31.25%), and the difference was statistically significant (p <0.05). There were 40 cases (62.5%) of type Ⅰ respiratory failure patients were significantly more than 24 cases (37.5%) of type Ⅱ respiratory failure patients, and the difference was statistically significant (p <0.05). PaO2 (OR = 1.08, 95% confidence interval 0.94-1.24), pH (OR = 1.42, 95%, confidence interval 1.09-1.64), PaCO2 (OR = 0.95, 95% , Confidence interval 0.86-1.19). (OR = 0.84, 95% confidence interval 0.71-0.99), age (OR = 0.91, 95% confidence interval 0.84-1.04), and blood lactate content (OR = 1.09 , 95% confidence interval 0.90-1.32). CONCLUSIONS: There was no significant correlation between hospital stay and mortality in patients with respiratory failure and time spent in the emergency room.
