目的:探讨急诊治疗严重哮喘呼吸衰竭的临床疗效.方法对我院收治的86例严重哮喘呼吸衰竭患者进行回顾性分析,在给予常规治疗的基础上采用无创机械通气治疗,对患者治疗前后动脉血气、生命体征等指标变化及临床疗效进行观察.结果与治疗前相比,治疗后患者心率、呼吸频率、PaCO2明显下降(P<0.05),pH、SaO2、PaO2有所升高,前后对比差异具有统计学意义(P<0.05).结论急诊治疗严重哮喘呼吸衰竭患者,在常规治疗基础上采用无创通气治疗,可有效改善血脉血气及临床症状,从而降低死亡率与气管插管率,疗效显著,值得临床推广. “,”Objective To investigate the clinical effect of the treatment of respiratory failure emergency treatment of severe asthma.Methods In 86 cases of severe asthma patients with respiratory failure were retrospectively analyzed, on the basis of given routine therapy using noninvasive mechanical ventilation therapy, vital signs index changes and clinical curative effect observation.Results After treatment in patients with heart rate, breathing rate, PaCO2 signiifcantly decreased (P〈0.05), pH, SaO2, PaO2was increased, compared before and after the differences statistically signiifcant (P〈0.05).Conclusion The emergency treatment of severe asthma patients with respiratory failure, on the basis of conventional treatment using noninvasive ventilation treatment, curative effect is distinct, worth clinical promotion.
