[Evaluation of selected factors modifying blood loss after total hip arthroplasty and techniques for the prevention of protracted postoperative bleeding].
The aim of this work was to evaluate blood loss in total hip arthroplasty patients, to determine the effect of some factors on bleeding including age, gender, blood group, body build, bone density, and hip replacement technique, and to develop a method for preventing excessive and protracted postoperative bleeding. Altogether, 59 patients with degenerative hip disease were enrolled. Postoperative bleeding was determined after 12 and 24 hours from surgery by measuring the volume of blood in flasks connected to Redon suction drains. The mean volume of blood lost after hip arthroplasty was 797.3 mL after 12 hours and 1029.4 mL after 24 hours. Total blood loss after surgery was 1257.9 mL. No statistically significant differences in blood loss were noted depending on body weight. In consequence, the percentage of blood lost in relation to total blood volume was determined. This indicator was found to be the only objective measure of blood loss in hip arthroplasty patients. Postoperative bleeding was smaller in patients with higher systolic blood pressure intraoperatively, reduced bone density in the femoral neck and spine, and in females. A tendency to reduced bleeding was observed in the elderly and for shorter surgery times. Blood group and hip replacement technique had no effect on blood loss.
