NIRS and DO2i Correlation

Conditions
Perfusion; Complications
Multiorgan Failure
Registration Number
NCT03281707
Lead Sponsor
Centro Cardiologico Monzino
Brief Summary

This study evaluates the association between near infrared spectroscopy (NIRS) and indexed oxygen delivery (DO2i) and their possible correlation with postoperative organ failure.

Detailed Description

Literature evidences show that levels of DO2i under 262-272 mL/min/m2 during cardiopulmonary by-pass (CPB) are associated with an increased incidence of acute kidney injury (AKI).

Furthermore, it has been demonstrated that keeping a NIRS of 75-80% compared to the basal value reduces the risk of perioperative morbidity. On the other hand, a NIRS \< 50% of basal value seems to be predictive of an increase in morbidity.

All of those studies had been performed during CPB and knowledge lacks in management of DO2i and NIRS before and after CPB.
