Clinical analysis of sequential mechanical ventilation in the treatment of patients with pulmonary heart disease complicated with type-II respiratory failure

Objective To explore the methods and to evaluate the efficacy of sequential invasive and non-invasive mechanical ventilation in the treatment of patients with pulmonary heart disease complicated with type-Ⅱ respiratory failure.Methods 60 PHD patients complicated with type-Ⅱ respiratory failure were all intubated and given mechanical ventilation.The patients were randomly and evenly divided into two groups when the indications of ventilator replacement appeared.The treatment group were extubated and given non-invasive mechanical ventilation,and the control group were continuously given invasive mechanical ventilation.Blood gas analysis,mortality,incidence of VAP,duration of mechanical ventilation and hospital stay were observed and compared between the two groups.Results There was no significant difference of curative effect between the two groups(P0.05),but the improvement of mortality,incidence of VAP,duration of mechanical ventilation and hospital stay were more pronounced in the treatment group than in the control group(P0.05).Conclusion The sequential invasive and non-invasive mechanical ventilation can lower the incidence of VAP and mortality and shorten the duration of mechanical ventilation and hospital stay in the treatment of pulmonary heart disease patients complicated with type-Ⅱ respiratory failure.
