[摘要] 目的:探讨呼气末正压(PEEP)通气在抢救急性心肌梗死(AMI)并重度急性左心衰竭和呼吸衰竭的疗效和临床应用价值。方法:将18例AMI并重度急性左心衰竭和呼吸衰竭患者行呼气末正压通气(PEEP)治疗前后的呼吸频率、心率、血气分析、血氧饱和度、氧合指数及临床表现进行分析。结果:18例AMI并重度急性左心衰竭和呼吸衰竭患者经PEEP治疗后,呼吸频率、心率、血气分析、血氧饱和度及氧合指数差异均有统计学意义(P<0.05)。结论:PEEP是抢救AMI并重度急性左心衰竭和呼吸衰竭的有效方法之一。

[Abstract] Objective: To explore the exhale positive pressure ventilation (PEEP) in salvage acute myocardial infarction (AMI) and severe acute heart failure left and breath curative effect and clinical application value. Methods: Eighteen cases of AMI and severe acute left heart failure and respiratory failure patients do positive end-expiratory pressure (PEEP) before and after treatment, the heart rate, the frequency of breathing, blood gas analysis, blood oxygen saturation, oxygen and index and clinical manifestations were analyzed. Results: Eighteen cases of patients with AMI and severe acute respiratory failure left heart failure and the patients' PEEP after treatment, breathing, heart rate, blood gas analysis, blood oxygen saturation and oxygen and index had significant difference (P<0.05). Conclusion: PEEP is rescue AMI and severe acute respiratory failure left heart failure and one of the important one of effective method.

急性左心衰竭是大面积急性心肌梗死(acute myocardial infarction,AMI)和老年人AMI常见的严重并发症,主要表现为急性肺水肿和心源性休克,而且常合并急性呼吸衰竭,病情危重,救治难度大,死亡率高,如不及时采取积极有效抢救措施,将危及生命。目前关于AMI合并急性左心衰竭应用无创正压通气治疗的报道较多,然而,在AMI并重度急性左心衰竭患者应用无创正压通气治疗依从性差,不少治疗失败。近年来,笔者在AMI并重度急性左心衰竭并呼吸衰竭应用呼气末正压通气治疗取得了良好疗效,挽救了不少患者的生命。现将18例AMI合并急性左心衰竭和呼吸衰竭患者应用呼气末正压通气治疗的临床体会,进行总结如下:
1资料与方法
1.1一般资料
本文收集2006年1月~2011年1月入院的AMI并重度急性左心衰竭和呼吸衰竭患者共18例,其中,男13例,女5例,年龄60~87岁。18例均符合下列条件:①AMI的诊断依据缺血性胸痛的临床病史、心电图的动态演变和心肌坏死的血清心肌标志物浓度的动态改变;②急性心力衰竭采用Killip分级法 ......
