Impact of SpHb Monitoring on Transfusion

Continuous and noninvasive hemoglobin (SpHb) monitoring provides clinicians with real-time trending of changes or lack of changes in hemoglobin, which has the potential to alter red blood cell (RBC) transfusion decision making. The objective of this study was to evaluate the impact of SpHb monitoring on RBC transfusions in high blood loss surgery. The investigators hypothesize that SpHb will improve blood transfusion practice in the for of change the number of blood unit per patient and improve the outcome regards the time to take decision of transfusion trigger.
