Brief Summary:
Estimated blood loss is an important parameter recognized as a standard practice in anesthesiology and others medical specialties, with relevant clinical and research applications. Currently is no model capable of accurately estimate blood loss. The purpose of this study is to evaluate the accuracy of a novel model.
