摘要
目的观察有创机械通气辅助治疗急性左心衰的治疗效果。方法回顾性分析25例经有创机械通气治疗的急性左心衰患者的临床资料,比较机械通气治疗前后患者的心率、呼吸频率、血压、血气分析及血流动力学的变化。结果机械通气治疗2h后,患者上述观察指标均较治疗前显著好转。21例患者(成功组)有创机械通气撤机成功,总有效率为84.0%(21/25);4例患者(失败组)有创机械通气撤机失败,3例死亡,病死率为12.0%(3/25),1例撤机失败转外科。成功组心排血量(cardiac output,CO)和心排血指数(cardiac index,CI)较失败组明显改善。2组间年龄、机械通气时间比较,差异无统计学意义(P>0.05),而急性生理学及慢性健康状况评分Ⅱ(acute physiology and chronic health evaluation Ⅱ,APACHEⅡ)评分比较,差异有统计学意义(P<0.05)。结论有创机械通气治疗是抢救急性左心衰的有效辅助治疗措施。
Objectives To evaluate the effects of invasive mechanical ventilation on adjunctive therapy of severe acute left heart failure. Methods Twenty-five patients with acute left heart failure admitted to the intensive care unit （ICU） were investigated retrospectively. All patients received mechanical ventilation. Changes of heart rate, respiratory rate, blood pressure, blood gas analysis and cardiopulmonary management system were observed. Results Most patients were improved apparently with invasive mechanical ventilation after treating 2 h. There were 21 patients sucessed to remove the mechanical ventilation equipment （successful group）, the successful rate was （21/25） 84%. There were 4 patients failed to remove the mechanical ventilation equipment （failure group）, 3 of them died and the dead rate was （3/25） 12%, one of them needed to perform surgery. Cardiac output （CO） and （or） cardiac index （CI） was significantly improved in the successful group than those in the failure group. The age and time of mechanical ventilation between 2 groups had no significance （P 〉 0.05） , while the score of acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） between 2 groups had significance （P 〈 0.05）. Conclusions Invasive mechanical ventilation is a kind of effctive method in adjunctive therapy of severe acute left heart failure.
