Blood Loss, Postoperative, Blood Loss, Surgical, Postoperative Complications
Conditions
Brief summary
Blood loss quantification during surgery remains unreliable and inaccurate. The purpose of the study is compare several methods of blood loss quantification in real surgical settings and to analyze the effect of blood loss on postoperative complications.
Interventions
Measurement of external blood loss
Serum Hemoglobin concentration
Sponsors
Study design
