Blood loss in prosthetic hip replacement is not influenced by the AB0 blood group.
OBJECTIVE
To find out if there is a correlation between AB0 type and the amount of blood lost at operation.


METHODS
Retrospective study.


METHODS
One county and one university hospital, Sweden.


METHODS
540 patients who underwent primary prosthetic hip replacement under regional anaesthesia. Albumin (n = 298) or dextran (n = 242) were used as plasma substitutes.


METHODS
Estimated blood loss and number of units of red cell concentrates transfused.


RESULTS
The characteristics of the study groups were similar. In patients given albumin, the mean (SD) intraoperative loss with blood group 0 (n = 100) was 718 (413) ml and 2.7 (1.9) red cell units were given. Those with other blood groups (n = 198) lost 713 (469) ml and were given 2.5 (2.0) units. In patients given dextran with blood group 0 (n = 82), the intraoperative blood loss was 650 (337) ml, the postoperative loss 480 (222) ml and they received 2.1 (2.1) units. The corresponding values in the patients with other blood groups (n = 160) were 665 (351), 498 (208) and 2.5 (2.1) units.


CONCLUSIONS
Blood group 0 was not associated with increased blood loss.
