【摘要】 目的观察双水平气道正压通气(BiPAP)呼吸机治疗急性重症哮喘的疗效。方法将48例急性重症哮喘的患者采用完全随机设计方法,分为治疗组(23例)和对照组(25例),对照组采用常规治疗,治疗组在常规治疗的基础上加用BiPAP呼吸机治疗,所有患者分别在治疗前及治疗4h后测定pH值、氧分压(PaO2)、二氧化碳分压(PaCO2)、心率(HR)和呼吸频率(RR)的变化。结果4h后各指标的改善情况治疗组明显好于对照组。结论BiPAP是治疗急性重症哮喘的一种较好的无创通气模式。更多还原

【Abstract】 Objective To evaluate the efficacy of biphasic intra-airway positive air pressure (BiPAP) respiratory therapy in patients with acute severe bronchial asthma. Methods Forty-eight patients suffering from acute severe bronchial asthma were randomly divided into two groups: control and treatment group. Patients in the control group was treated with conventional method and the treatment group was treated with both conventional and BiPAP. pH, PaO2, PaCO2, HR and RR were analyzed before and 4 h after therapy. The changes of clinical symptoms were also recorded. Results An improvement in the symptoms was observed in the treatment group at 4 h after the therapy. Conclusion BiPAP is an optimistic and non-traumatic method for treating acute severe bronchial asthma.更多还原
