Noninvasive hemoglobin monitoring for maintaining hemoglobin concentration within the target range during major noncardiac surgery: A randomized controlled trial
Primary resultResult — go to the resultRelative risk 0.24 95% CI 0.13–0.41Authors' conclusion
Compared with routine care, SpHb-guided management resulted in significantly lower rates of hemoglobin deviation outside the target range intraoperatively in patients undergoing major noncardiac surgeries with a potential risk of hemorrhage.
Study context
- Population
- Patients undergoing elective major noncardiac surgery with a potential risk of hemorrhage, university hospital

- Comparison
- SpHb-guided management vs usual care
- Primary endpoint
- Rate of deviation of laboratory total hemoglobin from target range (8-14 g/dL): tests revealing deviation / total laboratory tests during surgery
