机械通气联合多巴胺治疗心源性休克并呼吸衰竭的临床研究

Clinical efficacy of mechanical ventilation combined with dopamine in the treatment of cardiogenic shock combined with respiratory failure

目的观察心源性休克合并呼吸衰竭患者应用机械通气联合多巴胺治疗的临床疗效。方法观察我科10例心源性休克合并呼吸衰竭患者应用机械通气及多巴胺治疗前后平均动脉压(MAP)、心率(HR)、血气分析及临床症状、体征的变化,总结机械通气联合多巴胺在抢救心源性休克合并呼吸衰竭中的疗效。结果10例心源性休克合并呼吸衰竭患者应用机械通气联合多巴胺治疗后,2例死亡,其余8例病情好转,联合治疗后平均动脉压(MAP)升高,心率(HR)下降,动脉血氧饱和度(SaO2)及动脉氧分压(PaO2)、氧分压/吸入氧浓度(PaO2/FiO2)升高,患者的呼吸困难症状明显改善,肺部啰音明显减少?崧邸《杂谛脑葱孕菘税楹粑ソ呋?者,机械通气联合多巴胺治疗能及时有效地改善患者临床症状,增强心肌收缩力,增加心排血量,纠正低氧血症,降低心肌氧耗,降低死亡率,是抢救心源性休克的有效措施。

Objective To study the effects of mechanical ventilation combined with dopamine in the treatment of patients with cardiogenic shock combined with respiratory failure. Methods 10 patients with cardiogenic shock and respiratory failure were treated by mechanical ventilation combined with dopamine The changes of mean arterial pressure ,heart rate , arterial blood gas analysis as well as clinical symptoms were recorded and compared with each other before and after combined treatment. Results The condition of 8 patients were improved and 2 cases died after mechanical ventilation combined with dopamine. After combined treatment, mean arterial pressure rose, heart rate decreased, the blood oxygen saturation, PaO2, PaO2 / FiO2 rose, dyspnea was improved significantly and moist rales decreased rapidly. Conclusion Mechanical ventilation combined with dopamine can evidently improve clinical symptoms and hypoxemia , increase myocardial contractility and cardiac output, improve hypoxemia of patients with cardiogenic shock and respiratory failure and is an effective supplementary method for treating patients with cardiogenic shock.
