Effect observation of non-invasive mechanical ventilationassisted respiratory therapy in treatment of severe bronchial asthma patients complicated with type Ⅱ respiratory failure

  Objective  To investigate the clinical effect of non-invasive mechanical ventilation assisted respiratory therapy in the treatment of severe bronchial asthma patients complicated with type Ⅱrespiratory failure.

  Methods  Eighty-six severe bronchial asthma patients complicated with and type Ⅱrespiratory failure were randomly divided into two groups, with 43 cases in each group. The control group was given routine treatment, and the observation group was treated with non-invasive mechanical ventilation on the basis of the control group. Therapeutic effect was compared between two groups.

  Results  The success rate of rescue in the observation group was significantly higher than that in the control group (P<0.05). In the observation group, the time from ICU to general ward and the arterial partial pressure of oxygenp(O₂), arterial partial pressure of carbon dioxidep(CO₂) as well as arterial oxygen saturation (SaO₂) at 24 hours after treatment were significantly better than those in the control group (P<0.05).

  Conclusion  For severe bronchial asthma patients complicated with type Ⅱrespiratory failure, the effect of non-invasive mechanical ventilation is significant.
