摘要
目的为研究供体脑死亡对供体外周器官的影响,建立一种无脑电图仪监测下渐进式大鼠脑死亡模型。探讨大鼠脑死亡模型制作要点、成功率以及血流动力学参数。方法57只Fisher大鼠行动脉插管、气管插管、诱导建立脑死亡模型,取肾前维持机械呼吸6h。将平均动脉压(MAP)>80mmHg的脑死亡大鼠,取其肾脏原位移植给Lewis大鼠。另外10只Fisher大鼠作为正常对照组供体。结果57只Fisher大鼠中45只(78.9%)在6h的机械性人工呼吸观察中,MAP始终在正常水平,可作为脑死亡供体。10只正常对照组大鼠,MAP虽呈下降趋势,但仍在正常水平。来自脑死亡大鼠的肾脏移植后再灌注时间(22±7)min与来自对照组的(5±3)min相比差异具有显著性(P<0.001)。其余12只大鼠被剔除出研究。结论无脑电图仪监测下,渐进式建立大鼠脑死亡模型,可达到与标准方法建立的脑死亡模型相似的保持正常血压的效果,可用于改善脑死亡供体器官质量和移植物功能。
