Effect of haemodilution on transfusion requirements in liver resection.
Between April, 1988, and February, 1989, 22 consecutive patients underwent liver resection (17 hepatectomy, 5 segmentectomy) with intraoperative haemodilution to avoid blood transfusion. The results were compared with those of 22 patients who underwent liver resection without haemodilution between February, 1987, and April, 1988, and who were matched for the nature of the tumour and the type of liver resection. Age, preoperative haematocrit and haemoglobin concentration, and intraoperative blood loss did not differ between the groups who did and did not undergo haemodilution. There was no abnormal bleeding during liver transection in haemodiluted patients. No allogeneic blood products at all were needed in a significantly greater proportion of the group with haemodilution than of the group without (19 [86%] vs 6 [27%]). The two groups also showed significant differences in the total requirements of allogeneic packed red cells (haemodilution 9 units, no haemodilution 84 units) and fresh frozen plasma (9 vs 119 units). Although the haematocrit was slightly but significantly lower in the group who underwent haemodilution than in those who did not on postoperative days 1 and 8, the differences had disappeared by the second postoperative month. Postoperative complication rates, abnormal results in liver biochemical tests, and lengths of hospital stay were the same in patients with and without haemodilution. Intraoperative haemodilution in patients undergoing liver resection reduced requirements for all blood products, further lowering the risks associated with liver resection.
