This study was designed to find practical measurement to estimate blood loss in gynecologic surgery We analysis 24 patients who underwent total vaginal hysterectomy without irrigation from January 2012 to June 2012. Real blood loss was measured, calculating the weight of suction fluid and gauzes. The relation between real blood loss and other factors which were considered to show the amount of blood loss indirectly was analyzed using statistic program. The factors were measured one day before surgery and postoperative one day. Using the factors which showed statistical significance (p<0.05), regression equation to calculate blood loss was made. Among all factors (age, weight, height, BMI, BSA, Hb change, WBC change, hematocrit change, CRP change, ESR change, potassium change), age (p=0.023), height (p=0.049), Hb change (p=0.36) and square root of WBC (p=0.024) showed statistical significance. Using multiple linear regression, regression equation was made. EBL= -2343 + (-35.8)X( age, year) + (8.6)X(height ,cm ) + (115.4 X Hb change, g/dL) + (414.8 X SQRT (WBC)). The regression equation showed p=0.05. Gynecologists should estimate real blood loss with objective methods before reporting surgical outcomes and the safety and efficiency of surgical technique. Until now there is no simple and practical measurement to estimate real blood loss. The suggested regression equation have not sufficient statistical significance, but the equation will be modified to be more accurate with more data in the future.
