Such as blood loss> 1 / 3MABL, and <1MABL, with colloidal fluid. Such as blood loss> 1MABL, essential blood transfusion products.

Maximum allowable bleeding (MABL), preoperative determination of hematocrit (HCT) and estimated blood volume (EBV) in children MABL = EBV × (HCT-30) / HCT in children with blood loss <1 / 3MABL , With the balance solution. Such as blood loss> 1 / 3MABL, and <1MABL, with colloidal fluid. Such as blood loss> 1MABL, essential blood transfusion products.
