【摘要】 目的观察心肌梗死患者机械通气疗效。方法 43例采用机械通气的心肌梗死患者为治疗组 ,于PaO2 <5 5mmHg、SaO2 <85 % ,及心跳骤停时给予气管插管、机械通气 ;2 6例相同病情的患者为对照组 ,基本治疗方法相同而行经鼻或面罩吸氧。结果机械通气组存活 15例 (3 4.9% ) ,对照组存活 2例 (7.8% ) ,两组患者存活率的差异有非常显著性意义 (P <0 .0 1)。两组死亡患者的死亡时间多在 2 4h之内 ,机械通气组在行机械通气 1周后死亡人数明显增多。结论机械通气可明显提高心肌梗死患者的存活率 ,改善心功能。更多还原

【Abstract】 ObjectiveTo investigate the effect of mechanical ventilation (MV) on myocardial infarction (MI).Methods43 MI patients of the treating group were treated with mechanical ventilation when PaO 2<55 mmHg, SaO 2<85%. 26 MI patients of the control group were treated with same treatment except for inhaling O 2 through nose or face mask.ResultsThe survival rate of the treating group was 34.9%, but that of the control group was 7.8%, there was a significant difference between two groups ( P< 0.01).ConclusionMechanical ventilation can raise the survival rate of MI patients and improve functions of failing heart.更多还原
