Trial Outcomes & Findings for Evaluating Fluid Strategies in Thoracic Surgery Patients Utilizing a Goal Directed Approach (NCT NCT02135146)

NCT ID: NCT02135146

Last Updated: 2020-03-03

Results Overview

Acute renal injury as defined by the American Kidney Injury Network (AKIN) criteria in the first 72 hours postoperatively (serum creatinine levels). The AKIN scale will be used to assess the presence and severity of acute kidney injury (AKI). The AKIN is a classification/staging system of acute kidney injury developed by the Acute Kidney Injury Network which uses changes in serum creatinine (SCr) and urine output to assess AKI. Stages of acute kidney injury are defined as 1, 2, or 3, with 3 indicating the most severe AKI. (1) Increase ≥ 0.3 mg per dL (26.52 μmol per L) or ≥ 1.5- to twofold from baseline. (2) Increase \> two- to threefold from baseline. (3) Increase \> threefold from baseline or ≥ 4.0 mg per dL (353.60 μmol per L) with an acute rise of at least 0.5 mg per dL (44.20 μmol per L).
