The primary objective of this study was to investigate the relationship between \u0394IVC and the incidence of postoperative AKI in CABG patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A multicenter prospective cohort study was conducted from September 2021 to July 2022 in patients over 18 years of age who underwent elective CABG. We measured the diameter of the inferior vena cava (D-IVC) via M-mode TEE using the transgastric long axis (LAX) view (70\u00b0) of the IVC, approximately 2 cm caudal to the right atrium. All echocardiographic indicators were measured three times in a row at the following three time points: T0 (before the CABG surgery began), T2 (approximately 5-10 minutes after protamine neutralization), and T3 (after the sternum was closed), after which the values were averaged.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The association between the TEE index (\u0394IVC) and the incidence of postoperative AKI in patients with CABG was not statistically significant.
