急性心肌梗死患者应用主动脉内球囊反搏治疗时血小板减少的临床分析

Clinical analysis of thrombocytopenia applying to intro-aortic ball pump among patients with acute myocardial infarction

目的探讨急性心肌梗死患者应用主动脉内球囊反搏(IABP)治疗期间血小板减少的临床特点、处理及预后。方法入选我院2005年8月～2011年1月128例接受IABP治疗的急性心肌梗死患者,回顾性分析入选患者的血小板情况及临床特点。结果 128例患者应用IABP的时间为(86.4±7.1)h;应用IABP后有52例血小板减少患者,其中轻度减少者37例、重度减少者15例,无极重度患者;出现血小板减少的时间为开始IABP治疗后12h;停用IABP后有97.4%的患者血小板恢复至正常。结论急性心肌梗死患者应用IABP治疗时可出现明显的血小板减少,应该引起重视,在应用过程中应严密监测。

Objective To investigate the characteristics,treatment and prognosis of thrombocytopenia application intro-aortic balloon pump treating acute myocardial infarction patients.Methods From August 2005 to January 2011,we identified 128 acute myocardial infarction patients who accepted intro-aortic balloon pump treatment,and analyzed clinical characteristics of platelet retrospectively.Results Mean duration of intro-aortic balloon pump insertion of 128 acute myocardial infarction patients was（86.4±7.1） hours,52 patients have thrombocytopenia,37 patients with mild decreased platelet and 15 patients with severe decreased platelet;no extreme severe reduction condition;initial time of thrombocytopenia was 12 hours when intro-aortic balloon pump was used;platelet returned to normal of 97.4% patients when intro-aortic balloon pump was stopped.Conclusions Intro-aortic balloon pump treating acute myocardial infarction patients can induce thrombocytopenia.In order to reduce occurrence of condition,we should pay more attention and monitor strictly.
