Abstract
Objective: To investigate the influence of early mechanical ventilation on the respiratory mechanics and hemodynamics indexes of patients with respiratory failure caused by acute poisoning.Methods:A total of 24 patients with respiratory failure caused by acute poisoning who were treated with early mechanical ventilation from February 2009 to May 2012 were selected as observation group,and 24 patients who were treated with mechanical ventilation after respiratory arrest during the same period were selected as control group,then blood gas indexes,respiratory mechanics and hemodynamics indexes of the two groups before and 2,12 and 24 h after the treatment were compared.Results:2,12 and 24 h after the treatment,improvements in blood gas indexes,respiratory mechanics and hemodynamics indexes of the observation group were significant more obvious than that of the control group,those indexes of observation group showed an continuous improvement after the treatment,and were all significant better than that before treatment(P0.05).Conclusion:Early mechanical ventilation can significantly improve the prognosis of patients with respiratory failure caused by acute poisoning.And it can effectively improve the respiratory mechanics and hemodynamics indexes.
