IABP对重症冠脉搭桥术患者循环支持的对比研究

Comparative restarch of circulation support by IABP to the serious patients of bypass operation of coronary artery

目的评价重症冠脉搭桥术患者经主动脉内气囊反搏(IABP)循环支持治疗的可行性及其效果。方法16例重症冠脉搭桥术患者(EF≤0.40)分别于术前、术中给予IABP循环支持治疗,以同时期同一疾病未经IABP治疗的冠脉搭桥术患者(EF>0.40)作为对照组进行比较、观察其循环复苏后的血压、心率、心功能,脏器功能不全或衰竭的发生数等指标。结果两组间年龄、性别、冠状动脉病变支数无显著性差异;IABP循环支持治疗后的重症冠脉搭桥术患者组较未经IABP治疗的冠脉搭桥术对照组患者收缩压、舒张压、心功能分级及器官功能不全发生数均无显著性差异。结论对重症冠脉搭桥术患者尽早进行IABP治疗具有明显的循环支持治疗效果,能明显减少并发症,提高重症冠脉搭桥术患者的手术成功率。

Objective To evaluate the feasiblity and effect of circulation support by IABP to the serious patients of bypass operation of coronary. Methods The 16 serious patients （EF ≤0. 40） of bypass operation of coronary artery were given circulation support by IABP before operation and in op- eration. The patients （ EF 〉 0.40） were as control group. To compare blood pressure, heart rate, heart function and incidenec of organ functional defect or depletion in the two groups after resuscitation. Resuits No significant difference in age, gender and the number of steonosis of coronary artery between two groups. No significant difference in contractive pressure, diastolic blood pressure, cardiac functional grading and incidence of organ funcional defect or depletion between two groups. Conclusion The serious patients of bypass operation of coronary artery were early given IABP to obstain better circulation support, to decrease complication obviously and elevate operation success ratio.
