The effect of fresh autologous blood transfusion on platelet count and blood requirement in the early postoperative period is examined in a control group and in patients receiving early and late autologous replacement. Withdrawal of blood in the autologous groups appeared to enhance platelet numbers as the autologous groups had higher mean platelet counts than the control group immediately after bypass, in spite of having lower mean haematocrit. After bypass all groups showed a progressive rise in platelet count with time. A substantial part of the rise was explained by haemoconcentration resulting from fluid shifts but there was also an increase in the total circulating platelet numbers. There was no difference in postoperative blood loss between the three groups. Autologous blood replacement hastens the postoperative rise in platelet count but does not alter the postoperative blood loss.
在对照组以及接受早期和晚期自体血置换的患者中,研究了新鲜自体输血对术后早期血小板计数和血液需求量的影响。尽管自体血组的平均血细胞比容较低,但在体外循环后即刻,由于自体血组的平均血小板计数高于对照组,所以自体血组采血似乎使血小板数量增加。体外循环后,所有组的血小板计数均随时间逐渐上升。血小板计数上升的很大一部分原因是液体转移导致的血液浓缩,但循环血小板总数也有所增加。三组之间术后失血量没有差异。自体血置换可加速术后血小板计数上升,但不改变术后失血量。
