Relationship Between ORI and Blood Transfusion in Spinal Surgery

No results posted yet for this study

Summary

Concerns about the necessity and risks of blood transfusions have led to the search for new noninvasive monitoring methods. Oxygen reserve index (ORI), one of them, is a dimensionless index ranging from 0.00 (no reserve) to 1.00 (maximum reserve) according to oxygenation reserve status, and it is also a non-invasive and continuous measurement parameter. Some studies have examined ORi as an indicator for early detection of hypoxemia. There are reports in the literature that ORi and Pa02 values measured noninvasively during surgery are early precursors for desaturation and hypoxia.Researces aimed to investigate the relationship between perioperative blood transfusions and ORI in vertebral stabilization surgeries performed by the same surgical team in our clinic.

Conditions

  • Perioperative Hemorrhage

Interventions

PROCEDURE

Stabilization surgery

hourly blood gas analysis and hemoglobin and hematocrit control and blood transfusion will be performed when necessary If a low pO2 value is observed in the blood gas, the fi02 values or fresh gas flow will be increased.
