摘　　要：我们的实验结果表明双腔主动脉内气囊 (DIAB)反搏的效果要优于单腔主动脉内气囊 (SIAB)反搏的效果。它明显地改善血流动力学参数 ,进而提高了反搏的功效。也未发现双腔主动脉内气囊进行反搏会对肾脏的血流动力学参数产生不良影响。在对比肾动脉去神经前后主动脉内气囊反搏的结果 ,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。这是当气囊进行反搏时 ,使肾脏血液循环得以改善的最重要因素。Our experimental results showed that the effects of double chamber intra aortic balloon pumping (DIABP) were better than that of single chamber intra aortic balloon pumping (SIABP) on the hemodynamics. The effects of double chamber intra aortic blloon pumping (DIABP) on hemodynamic parameters in the kidney were also studied. Before and after removing the renal nerve system, the DIABP was used and the results were compared. The pulse produced by pumping activated the renal nervous system and reduced the renal vascular resistance. Therefore the reduction of the renal vascular resistance is an important reason for the increase the renal blood flow during intra aortic balloon pumping. No negative effect of both cases was observed. DIABP significantly improved the hemodynamic parameters and increased the efficiency of the counterpulsation.
