摘要
本研究对比了双腔和单腔主动脉内气囊反搏对肾脏血流动力学各参数的影响，发现双腔主动脉内气囊反搏未引起肾脏的血流动力学参数不良变化。对比肾动脉去神经前后主动脉内气囊反搏结果发现，反搏时产生的脉动会对血管神经系统产生刺激，从而降低肾血管局部的阻力。这是气囊反搏使肾脏血流量增加的最重要因素。
The effects of the double chamber intra-aortic balloon (DIAB) and the single chamberintra-aortic balloon (SIAB) on the hemodynamic parameters in the kidney were studied. Nonegative effect of both cases was observed.Before and after removing the renal nerve system, the DIAB was used and the resultshad been compared. The pulse produced by pumping activized the renal nerve system and re-duced the renal vascular resistance.Therefore the reduction of the renal vascular resistance is an important reason for in-creasing the renal blood flow during intra-aortic balloon pumping.
