Abstract
Several methods have been found to be successful in reducing the need for allogeneic transfusion among the patients
undergoing total hip replacement. The purpose of this prospective study was to analyse the quality and evaluate the effect
of postoperative autotransfusion on the need for allogeneic transfusion following total hip replacement. The prospective
study was performed in two groups of patients undergoing total hip replacement. Before the operative procedure all patients
in both groups predonated two doses of autologous blood. In GROUP 1. the system for postoperative collection and
transfusion of shed blood was used. In GROUP 2. the patients underwent total hip replacement without blood salvage
system. Standard suction collection sets were used postoperatively. In this group shed blood was not transfused to the patients.
The samples of preoperative donated autologus blood, allogeneic blood and postoperative collected autologous
blood were analysed for number of red cells, hemoglobin, hematocrit, platelets, white blood cells, values of potassium, sodium,
free hemoglobin and acid base status. The postoperatively blood salvage significantly reduced the use of allogeneic
transfusion among patients managed with total hip replacement (allogeneic transfusion received 12 % patients in Group
1 and 80% patients in Group 2; p<0.001). The values of red blood cells are significantly lower in postoperative collected
autotransfusion blood compared with preoperative collected autologous blood and allogeneic blood (p<0.001). The values
of potassium and acid base status were in normal range in postoperatively collected autotransfusion blood. These
values in preoperatively collected autologous blood and allogeneic blood were out of normal range; (p<0.001). In addition
to reducing the risk of complications that are associated with allogeneic transfusion, postoperative blood salvage
may offer benefits including reducing the need for allogeneic blood. Our study confirmed that postoperative collection
and transfusion of drainaged blood is simple and safe method that significantly reduce the need for allogeneic transfusion
in patients underwent total hip replacement. The blood collected and transfused postoperatively has lower values of
red blood cells and normal values of potassium and acid base balance. The transfusion of this blood caused no complications
in our patients.
