ABSTRACT

Objective:

To investigate the urine output threshold of acute kidney injury in patients with acute pancreatitis(AP) and to guide early fluid therapy.

Methods:

The clinical data of AP patients from Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) were collected. The 24-h urine output rate [24-h urine output·kg-1·24-h-1, 24-UR mL/ (kg·h) ] and 48-h urine output rate [48-h urine output·kg-1·48-h-1, 48-UR mL/ (kg·h) ] were calculated, and according to the occurrence of acute kidney injury within 7 days (7-AKI), AP patients were divided into the 7-AKI group and non-7-AKI group. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of 24-UR and 48-UR on 7-AKI in AP patients. 24-UR and 48-UR were grouped according to the optimal cut-off value obtained from the ROC curve. Logistic regression was used to analyze the risk factors of 7-AKI, and Kaplan-Meier (KM) survival curve was drawn to analyze the effect of 24-UR and 48-UR on in-hospital mortality of AP patients.

Results:

A total of 713 AP patients were included, ROC curve analysis showed that the area under the ROC curve (AUC) of 24-UR in predicting 7-AKI in AP patients was 0.76. Based on the maximum Youden index, the cut-off value of 24-UR was 0.795 mL/ (kg·h) , and the AUC of 48-UR was 0.78 and the cut-off value of 48-UR was 0.975 mL/ (kg·h) . Logistic regression analysis showed that 24-UR≤0.795 mL/ (kg·h) was an independent risk factor for 7-AKI compared with 24-UR>0.795 mL/ (kg·h) ( OR 4.22, 95% CI1.50-11.85, P=0.006). Similarly, compared with 48-UR>0.975 mL/ (kg·h) , 48-UR0.975 mL/ (kg·h) was an independent risk factor for 7-AKI ( OR 3.75, 95% CI 1.45-9.72, P=0.007). The KM survival curve showed that the cumulative in-hospital survival rate in the high 24-UR group was higher than that in the low 24-UR group.

Conclusions:

24-UR can be used to guide early fluid therapy in AP patients.
