为了提高重症哮喘急性发作期患者的抢救成功率和降低气管插管率，我们提出了阶梯治疗方案，并对３１例患者观察了阶梯治疗方案的疗效。１２例Ⅰ组（ｐＨ７．３４～７．３）患者经Ａ方案治疗后全部痊愈，１１例Ⅱ组（ｐＨ７．２９～７．２）患者中，４例经Ａ方案、７例经Ｂ方案治疗后缓解，８例Ⅲ组（ｐＨ＜７．２）患者中，５例经Ｂ方案、２例经Ｃ方案治疗后改善（其中１例治疗前ｐＨ降至６．９７３，ＰａＣＯ_２高达１３．７ＫＰａ），另１例则因内科疗法无效，病情进行性加重而建立人工气道，机械辅助呼吸，后经巩固治疗，３１例患者全部痊愈出院。说明阶梯治疗方案可降低气插管率，提高抢救成功率。
In order to improve the success rate of rescue and reduce the rate of endotracheal intubation in patients with acute exacerbation of severe asthma, we proposed a step-treatment regimen and 31 cases observed the effect of step-treatment regimen. All 12 patients in group I (pH7.34 ~ 7.3) were treated with A regimen. Among 11 patients in group II (pH 7.29 ~ 7.2), 4 were treated with A and 7 with B After treatment, 5 of 8 patients in group Ⅲ (pH <7.2) were treated with B regimen and 2 regimens with C regimen (one of them had a pH of 6.973 before treatment and a PaCO 2 of 13.7 KPa) , While the other one was due to ineffective medical therapy, progressive aggravating illness and the establishment of artificial airway, mechanical assisted breathing, after consolidation treatment, all 31 patients were discharged. Step ladder treatment program can reduce the rate of gas intubation and improve the success rate of rescue.
