【摘要】 目的　观察无创机械通气时氧动力雾化吸入与超声雾化吸入治疗支气管哮喘的疗效区别。方法　 5 0例符合支气管哮喘急性发作患者随机分为 2组 ,即超声雾化吸入组 (A组 )和氧动力驱动雾化组 (B组 )各 2 5例。均吸入博力康尼令舒及爱喘乐 ,各 5 0 0 μg ,15min后观察各组临床症状改善情况。测定治疗前、治疗后 15min和 30min峰流速(PEF)的改变情况。结果　B组治疗后 15min、30min峰流速值与A组相比存在显著性差异 (P <0 .0 1)。B组治疗后症状及体征改善率显著优于A组 (P <0 .0 1)。结论　无创机械通气时氧气作动力雾化吸入在治疗支气管哮喘急性发作方面有更好的疗效 ,是一种快速、高效的方法更多还原

【Abstract】 Objective To observe the different therapeutic effect of noinvasive ventilation(NIPPV) in acute bronchial asthma with oxygen nebulae inhalation or ultrasound nebulae.Methods Fifty patients with acute bronchial asthma were divided into two groups: group A(n=25) treated with ultrasound nebulae inhalae; group B(n=25) treated with oxygen nebulae inhalae.All patiens with NIPPV inhaled Atrovent and Bricanyl solution. The improvement of clinical symptoms and peak flow(PEF) were observed. Results There was significant difference in PEF between group A and B in 15 minutes and 30 minutes, after treatment respectively (P<0.01). The improvement rates of signs and symptoms in group B were significantly superior to that of group A(P<0.01). Conclusion In NIPPV oxygen nebulae inhalation is a rapidly and highly effective approach in treatment of patients with acute bronchial asthma.更多还原
