Regardless of the means used to estimate blood loss, clinical observation of the patient with frequent assessment of cardiovascular status is that basis of total management. It is very important that EBL be reported with some accuracy using a device that has the ability to weigh blood loss. Why? The overall mortality rate from blood transfusion has been reported to be as high as one death per 5000 units given. This is a highly subjective number. There are undoubtedly cases in which death has resulted from the administration of one unit of blood. However, the most common pattern would be one in which a patient received many units of blood and still died as a result of his primary disease. Until recently, blood loss determination was merely a function of estimation or clinical observation due to the previously mentioned drawbacks of manual scale systems. With new advances in computers, the ease at which blood soaked sponges can now be weighed and calculated can be as simple as a touch of a button.
无论采用何种方法估算失血量，对患者进行临床观察并频繁评估心血管状态都是整体治疗的基础。使用能够称量失血量的设备准确报告估计失血量（EBL）非常重要。为什么呢？据报道，输血的总体死亡率高达每输注5000单位就有一人死亡。这是一个非常主观的数字。毫无疑问，有因输注一个单位血液而导致死亡的病例。然而，最常见的情况是患者接受了多个单位的血液，但最终仍因原发性疾病死亡。直到最近，由于手动秤系统存在上述缺点，失血量的测定仅仅是估计或临床观察的结果。随着计算机技术的新进展，现在称量和计算浸血海绵变得轻而易举，只需轻轻一按按钮即可。
