In 20 patients under regular dialysis with an arteriovenous fistula in one forearm, platelet counts were measured in blood taken simultaneously from the cubital vein, the arterialized vein near the site of anastomosis, the femoral vein, and the femoral artery. Samples of blood from the fistula and from the cubital vein of the opposite limb were taken with and without stasis. The highest values were found in blood taken from the cubital vein without stasis. Platelet counts were identical in femoral artery and vein, but were 4.8 and 4.9%, respectively, lower than the cubital vein values. Platelet counts from fistula blood taken without stasis were 13.7% lower than in the cubital vein. Platelet counts were lower when samples of blood were taken with stasis: 11.2% in the cubital vein, 7.4% in fistula blood. The awareness of these differences is of practical importance for platelet behavior studies.
在20例使用一侧前臂动静脉内瘘进行规律透析的患者中，同时从肘静脉、吻合口附近的动脉化静脉、股静脉和股动脉采集血液，测定血小板计数。在有和无血流淤滞的情况下，分别采集来自内瘘和对侧肢体肘静脉的血样。无血流淤滞时从肘静脉采集的血液中血小板计数最高。股动脉和股静脉中的血小板计数相同，但分别比肘静脉中的值低4.8%和4.9%。无血流淤滞时从内瘘血液中测得的血小板计数比肘静脉中的低13.7%。有血流淤滞时采集的血样中血小板计数较低：肘静脉中为11.2%，内瘘血液中为7.4%。了解这些差异对于血小板行为研究具有实际意义。
