呼吸衰竭患者入急诊抢救室时间与疾病预后的关系研究

目的：探讨呼吸衰竭患者入急诊抢救室时机与疾病预后的关系。方法回顾性总结我院2010年因呼吸衰竭入急诊抢救室的83例患者的资料。结果工作时间进行急诊抢救者74.7%（62/83）明显高于休息时间抢救者25.3%（21/83）（P＜0.05），Ⅰ型呼吸衰竭者60.2%（50/83）明显大于Ⅱ型呼吸衰竭者39.8%（33/83）（ P ＜0.05）。与住院时间延长有关因素包括：年龄（OR=0.97，95%置信区间0.87-1.01），吸烟史（OR=0.89，95%置信区间0.76-0.97）和血液中乳酸含量（OR=1.01，95%置信区间0.90-1.22）。影响死亡率的因素有pH值（OR=1.22，95%置信区间1.18-1.35）、PaO2值（OR=1.08，95%置信区间0.98-1.20）和PaCO2值（OR=0.97，95%置信区间0.82-1.13）。结论呼吸衰竭患者的死亡率及住院时间与入急诊抢救室的时机无明显相关。

Study on the relationship between the time of patients with respiratory failure in emergency resuscitation room and the prognosis of the disease

Objective To explore the relationship between the time of patients with respiratory failure in emergency resuscitation room and the prognosis of the disease. Methods The data of 83 cases with respiratory failure in emergency resuscitation room of our hospital in 2010 were retrospectively summarized. Results The proportion of patients who were rescured in the working time was 74.7% （62/83）, which was significantly higher than that in the rest time25.3%（21/83）], P 〈 0.05, and the proportion of patients with type I respiratory failure who were rescured was 60.2%（50/83）, which was significantly higher than that of patients with type II respiratory failure39.8%（33/83）], P〈0.05. The factors associated with prolonged hospitalization time included age（OR=0.97, 0.87-1.01 95% confidence interval）, smoking history（OR=0.89, 0.76-0.97 95% confidence interval） and blood lactate content（OR=1.01, 0.90-1.22 95% confidence interval）. The factors affecting mortality included pH value（OR=1.22, 1.18-1.35 95% confidence interval）, PaO2 value（OR=1.08, 0.98-1.20 95% confidence interval） and PaCO2 value （OR=0.97, 0.82-1.13 95% confidence interval）. Conclusion The mortality of patients with respiratory failure and hospitalization time are not significantly related to the time in emergency resuscitation room.
