U.S., Jan. 30 -- ClinicalTrials.gov registry received information related to the study (NCT06799832) titled 'Urethral PeRfusion Index-Guided Hemodynamic ManagemenT in Patients Having Major Abdominal Surgery: the UPRIGHT Randomized Feasibility Trial' on Jan. 23.

Brief Summary: We will perform this single-center pilot trial to determine if the intraoperative urethral perfusion index is higher in patients assigned to maintaining postinduction baseline urethral perfusion index than in patients assigned to routine care (with blinded urethral perfusion index monitoring). As pre-planned substudies, we will also assess the agreement between a) urethral perfusion index-derived pulse rate and heart rate measured with an electrocardiogram and b) betw...
