Abstract
Direct measurement of blood loss has poor reliability and poor validity. A formula is proposed for how blood loss may be calculated from pre- and post-operative haemoglobin, taking the influence of any blood transfusions into account.
摘要
直接测量失血量的可靠性和有效性都很差。本文提出了一个公式，用于根据术前和术后血红蛋白计算失血量，并考虑了任何输血的影响。
