Abstract:

Objective

To explore the association between venous excess ultrasound score(VExUS) and acute kidney injury (AKI) in patients with sepsis.

Methods

A prospective study was conducted on 54 sepsis patients admitted to the ICU of Zhejiang Hospital from October 2022 to December 2023.Based on whether AKI occurred during their stay in the ICU, all patients were divided into an AKI group (25 cases) and a non-AKI group (29 cases).The general clinical data, hemodynamic indicators, laboratory indicators, venous congestion, and cardiac ultrasound indicators were compared, and the generalized estimating equation (GEE) was used to evaluate the correlation between VExUS and AKI in sepsis patients.

Results

The sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation(APACHE) II score, creatinine, urea nitrogen, procalcitonin (PCT), brain natriuretic peptide (BNP),and 72-h fluid balance in the AKI group were higher than those in the non-AKI group, while the glomerular filtration rate (eGFR), hemoglobin, and 72-h total urine output were lower (all P <0.05).The VExUS of the AKI group on the first day [1.0 (0.0, 2.2) vs.0.0 (0.0, 1.0)], third day [2.0 (1.0, 3.0) vs.1.0 (0.0, 2.0)], and fifth day [1.0 (0.0, 2.0) vs.0.0 (0.0, 1.0)] was higher than that of the non-AKI group (U=2.349, 2.441, 2.536; P=0.019, 0.015, 0.011).VExUS was positively correlated with the fluid balance, peripheral sign score, and BNP (r = 0.314, 0.287,0.351; all P <0.05).GEE analysis found that VExUS [odds ratio = 1.661, 95% confidence interval (1.180, 2.339), P = 0.004] was an independent risk factor for AKI in sepsis patients.

Conclusions

VExUS is associated with the occurrence of AKI during ICU stay for sepsis patients.Bedside ultrasound is helpful in evaluating venous congestion and guiding volume management strategies.
