目的探讨双水平正压通气在重症哮喘治疗中的疗效。方法随机将40例重症哮喘患者分为对照组(20例)与实验组(20例)。对照组给予常规内科治疗,实验组在其基础上结合无创机械通气治疗。结果治疗前后相比较,两组临床症状均有缓解,P<0.05。实验组疗效较对照组显著,P<0.05。比较治疗6h、24h后两组血氧饱和度好转程度,实验组较对照组改善显著,P<0.05。结论内科治疗结合无创双水平正压通气可显著改善重症哮喘病状,使血氧饱和度、心率及呼吸频率得到明显改善,医疗价值较大。
Objective To investigate the efficacy of bi-level positive pressure ventilation in the treatment of severe asthma. Methods 40 patients with severe asthma were randomly divided into control group (20 cases) and experimental group (20 cases). The control group was given conventional medical treatment, and the experimental group was combined with noninvasive mechanical ventilation on the basis of it. Results Before and after treatment, clinical symptoms of both groups were relieved, P <0.05. The experimental group than the control group, P <0.05. Compared with the control group, the improvement of blood oxygen saturation of the two groups was better than that of the control group at 6h and 24h after treatment (P <0.05). Conclusion The combination of medical treatment and noninvasive bi-level positive pressure ventilation can significantly improve the severity of asthma and improve the oxygen saturation, heart rate and respiratory rate significantly, with great medical value.
