Observational StudyAssociation Between Changes in Norepinephrine Infusion Rate and Urinary Oxygen Tension After Cardiac Surgery.
To determine if the administration of norepinephrine to patients recovering from on-pump cardiac surgery is associated with changes in urinary oxygen tension (PO2), an indirect index of renal medullary oxygenation. ⋯ In patients recovering from on-pump cardiac surgery, changes in norepinephrine dose are associated with reciprocal changes in urinary PO2, potentially reflecting an effect of norepinephrine on renal medullary oxygenation.
