Methods: 56 cases with acute failure of left ventricular and respiratory in Yichang Central People's Hospital from June 2006 to December 2007 were analyzed prospectively. 24 cases were treated with combination of mechanic ventilation and sedative after emergency tracheal intubations. 32 cases were treated with traditional drugs. Clinical signs, blood gas analysis, mortality, and mean hospitalization time after treatment were compared between two groups.
