Curative effect of mechanical ventilation in acute respiratory distress syndrome caused by severe thoracic injury

OBJECTIVE To observe the clinical efficacy of mechanical ventilation in severe respiratory distress syndrome caused by thoracic trauma.METHODS 60 patients selected complied with the standard were randomly divided into two groups,each group 30 cases.2 groups were given aminophylline,corticosteroids,antibiotics and other symptomatic treatment,while the control group received supplemental oxygen,tracheotomy,intubation and other symptomatic treatment.Observation group was given the mechanical ventilation.Observed the results of blood gas analysis,pulmonary function test and other indicators before and after treatment.RESULTS The clinical control rate were 36.67%,20.00% in control group,there was a significant difference(P﹤0.05).The total effective rate was 76.67% in observation group and control group 66.67%,there was a significant difference(P﹤0.05).PaO2,PaCO2,SaO2 were measured before and after treatment in two groups,there were significant differences(P﹤0.05).After treatment,Cdyn,MVV,FEV0.3 and other indices were significantly different(P﹤0.05),FVC was not significantly different in two groups(P﹥0.05).CONCLUSION Mechanical ventilation combined with drug treatment in respiratory distress syndrome caused by severe chest trauma has a better clinical efficacy,and can significantly improve lung function.
