Background: One of the main problems for physicians is measuring bloodloss during surgery. Despite anesthesiologists and surgeons' understanding of the inaccuracy of visual estimation, it remains the foundation for estimating surgical blood-loss. The goal of this research was to estimate the blood-loss of patients having hip surgery. Method: Total 40 patients were enrolled. Total blood-loss was measured by determining intra-operative and post-operative blood-loss and adding them together. Pre-operatively and 24 hours after surgery, blood samples were collected from the patients to assess hemoglobin and hematocrit. The requirement of blood transfusion was noted. Results: The mean intra-operative, post-operative, and total bloodloss was 489.75±123.63ml, 205.43±63.31ml and 695.2±162.44ml respectively. Mean pre-operative and post-operative hemoglobin was 12.30±1.05 and 9.84±0.91 gm/dl respectively, thus drops in hemoglobin was by 2.46±0.14 gm/dl whereas mean pre-operative and post-operative hematocrit was 36.03±3.15% and 29.30±2.36% respectively. There was a drop in hematocrit by 6.73±0.79%. Out of 40, 15(37.5%) patients received blood transfusion postoperatively. Conclusion: In hip surgery most of the intra-operative and postoperative blood-loss occurs in the initial 24 hours of surgery. "Intra-operative blood-loss" and "transfusion rate" are not adequate predictors of total bloodloss.
