重症哮喘合并呼吸衰竭的呼吸机治疗观察

目的观察小潮气量机械通气治疗重症哮喘的临床效果。方法58例重症哮喘患者均行机械通气为主的综合治疗,观察治疗效果及带机前后的pH值、PaO2、PaO2/FiO2、SpO2及PaCO2的变化。结果45例治疗后症状明显缓解,缓解率77.6%。9例死亡,4例自动出院,患者带机后各观察指标均得到明显好转,与带机前相比,差别具有统计学意义（P〈0.05）。结论采用以机械通气为主的综合治疗,是重症哮喘合并呼吸衰竭患者安全有效的治疗方法。

Curative Observation on Ventilation Therapy for Patient with Severe Asthma Combined with Respiratory Failure

Objective To observe curative effect of severe asthma with small tidal volume ventilation.Methods 58 cases of severe asthma patient were underwent ventilation therapy.The PaO2,pH,PaO2/FiO2,SpO2 and PaCO2 changes before and after therapy were observed.Results 45 cases had relieved in symptom with 77.6% and 9 cases were dead,4 cases discharged under their willing.All data after therapy were better than those before therapy with P<0.05.Conclusion The complex therapy mainly with ventilation might be effective method for severe asthma combined with RF.
