Abstract: Objective To evaluate the accuracy of different methods for estimating blood loss during burn wound excixion and skin grafting in pediatric patients with severe burn. Methods Twenty pediatric patients of both sexes aged 7 days-8 yr weighing 4-22 kg undergoing burn wound excision and skin grafting were enrolled in this clinical study. Two methods were used for estimating blood loss during operation: Method Ⅰ: surgical surface area (SSA). MethodⅡ: the product of SSA and blood volume (BV). Total blood loss was calculated: total blood loss = BV ( Hct0 - Hctx ) ÷ Hct0 + Tx. Hct0 =Hct before operation. Hctx =Hct at the end of operation. Tx =total amount of blood transfusion. Results The correlation between the total blood loss and SSA was 0.776. The correlation between the total blood loss and the product of SSA and BV was 0.889. The difference was statistically significant. Conclusion The product of SSA and BV is more accurate in estimating blood loss during burn wound excision and skin grafting in children with severe burn.
