62例冠状动脉架桥术体外循环中的监护和处理

Monitoring and Management of 62 Cases of CABG During CPB

62例冠状动脉架桥术,灌流过程中进行了灌注压、中心静脉压、左房压和泵压等血流动力学指标和混合静脉血氧饱和度监测。维持灌注压在7.33kPa左右,混合静脉血氧饱和度在70％以上,升降温时混合静脉血氧饱和度变化较大,作相应的灌流量调整。灌注过程中用硝普钠、硝酸甘油、氟烷及阿拉明和改变灌流量等调整灌注压。灌注并发症少,效果满意。

With monitoring of perfusion pressure, CVP, LAP, pump pressure and SvO_2 forperfusion in 62 cases of CABG during CPB, it was managed to make a perfusionpressure about 7.33kPa and SvO_2 more than 70%. It was found that SvO_2 changedmore during heat change. Perfusion blood flow was adjusted according to hemody-namic and SvO_2 parameters and perfusion pressure made about 6.67～8.00 kPa withthe administration of nitroprusside, nitroglycerine, fluothane, aramine or by changingof perfussion flow. The result of perfusion of CABG was satisfactory.
