| Objective: To explore the value of peritoneal to abdominal height ratio(PAR)in the early prediction of acute pancreatitis(AP)and acute kidney injury(AKI).Methods: A retrospective analysis of the AKI status of 192 hospitalized AP patients from January 2019 to June 2020.The clinical data of 32 patients in the AKI group and 160 patients in the NAKI group,the first laboratory examination data after admission,the value and change of creatinine after admission were recorded,and the BISAP score was performed to calculate the PAR and the ratio of the maximum anteroposterior diameter to the maximum transverse diameter And record prognostic indicators such as mortality.Analyze the differences in indicators between the two groups,draw the receiver operating characteristic(ROC)curve for the indicators with statistical significance,calculate the area under the curve(AUC)and the effectiveness of the diagnosis of AKI.Results: The number of days of hospitalization,admission to the intensive care unit,renal replacement therapy and death probability of patients in the AKI group were higher than those in the NAKI group(P<0.05).Patients with alcoholic acute pancreatitis seem to be more prone to AKI(P<0.05).The differences in BISAP score,PAR,RBS,urea nitrogen,cystatin,uric acid,CRP,and serum calcium ion between the two groups were statistically significant(P<0.05).The AUC of PAR predicted AP-related AKI was 0.705,the sensitivity was 78.12%,and the specificity was 56.25%.PAR predicts SAP,death,ICU admission,and CRRT AUC of0.769,0.908,0.729,0.776,respectively.Among them,the predictive performance of death is the best.When the PAR threshold is greater than 0.51,AUC=0.908,sensitivity 100%,specificity 78.8%.Conclusion: As a new,simple and objective measure of intra-abdominal pressure,PAR can provide new clues for the early diagnosis of AP combined with AKI,and has high predictive value. |
