不同透析液对慢性血液透析患者动脉血气的影响

The Effects of Different Dialysates on Arterial Blood Gas in Chronic Hemodialysis Patients

作者采用碳酸氢盐、醋酸盐两种透析液患者进行慢性血液透析治疗。结果表明，醋酸盐透析（ＡｃＨＤ）可导致透后静脉低碳酸血症及一过性低氧血症。而用碳酸氢盐透析液的碳酸氢盐透析（ＢｉＨＤ）及透析滤过（ＨＤＦ）确能防止发生静脉低碳酸血症、低氧血症，且能有效地纠正代谢性酸中毒。我们认为，接受ＡｃＨＤ治疗的患者透析中出现＂醋酸盐不耐受＂现象，可能部分与醋酸盐透析液影响患者动脉血气变化有关。

In the present study, we investigated the effects of different dialysates on arterial blood gas in chronic hemodialysis patients. These results indicated that acetate hemodialysis might cause transient hypoxemia during the treatment, and hypocapnia after hemodialysis. However, bicarbonate dialysate did not result in these side effects as above stated, moreover, could correct metabolic acidosis swiftly. We suppose that acetate intolerance in hemodialysis patients treated with acetate dialysate may be partially related to change of arterial blood gas.
