The Effect of Non-invasive Hemoglobin Measurement in Hip Surgeries

Completed

• Conditions: Hemodynamic Instability; Bleeding; Hemorrhage
• Interventions: Device: non-invasive hemoglobin (SpHb)

• Registration Number: NCT04785274
• Lead Sponsor: Bulent Ecevit University

Brief Summary

Bleeding is one of the most important causes of mortality and morbidity in patients.

Hb levels are the most prevalently utilized monitoring parameter in hemorrhagic patients in the hemodynamic sense. Hemoglobin determination is studied at laboratories along with blood gasses or complete blood analysis. Recently, non-invasive techniques where measurement is made from the fingertips have been offered for use. One of these techniques is non-invasive hemoglobin (SpHb) measurement. SpHb is used as a trend monitor. Based on the severity of bleeding, the compensatory mechanisms of patients may be disrupted. This situation may lead to lower levels of toleration of anemia during bleeding. The relationship between blood transfusion and mortality is under debate.
