Evaluation Value Of CT Markers Combined With Pleural Effusion And Laboratory Markers In Acute Pancreatitis With Acute Respiratory Distress Syndrome

Objective:To explore the efficacy of CT indicators peritoneal to abdominal height ratio(PAR)in the acute pancreatitis(AP)with acute respiratory distresssyndrome(ARDS),and to explore the value of PAR combined with pleural effusion and laboratory indexs(serum calcium,blood p H,and partial pressure of oxygen)in evaluating AP with ARDS.Methods:The retrospective analysis of the ARDS status of 242 hospitalized AP patients from January 2019 to December 2022.The clinical data of 29 patients in the ARDS group and213 patients in the NARDS group,the first laboratory examination data after admission,p H value,the first value of blood oxygen saturation and oxygenation index after admission were recorded,the LIPS,MAPS score,pleural effusion,and measured the PAR value on plain CT scan,and recorded the occurrence time of ARDS.Analyzed the differences each index between the two groups,Spearman test was used to evaluate the correlation between various indicators and the occurrence of ARDS.Logistic regression analysis was performed on indicators with statistically significant differences,draw receiver operating characteristic(ROC)curve and get area under the curve(AUC)to compare the evaluation value of each indicator for AP with ARDS.Results:The number of days of hospitalization,pleural effusion,perform tracheal intubation,admission to the intensive care unit and death probability of patients in the ARDS group were higher than those in the NARDS group(P<0.05).The differences in age,sex,diabetes and pancreatitis of different etiology were no significant.The differences in Serum calciumion,CRP,albumin,p H value,fraction of inspired oxygen,oxygen saturation,blood oxygenation index,partial pressure of oxygen,PAR,LIPS and MAPS between the two groups were statistically significant(P<0.05).The AUC of PAR predicted AP with ARDS was 0.668,the sensitivity was 62.07%,and the specificity was 65.73%.The AUC of PAR combined with pleural effusion and laboratory indexs(serum calcium,blood p H,and partial pressure of oxygen)predicted AP with ARDS was 0.880,the sensitivity was 89.66%,and the specificity was 80.75%.Conclusion: PAR is a novel,fast and simple indicator to measure intra-abdominal pressure.It had a Low accuracy for AP complicated with ARDS when Used itself alone,PAR combined with pleural effusion and laboratory indexs(serum calcium,blood p H,and partial pressure of oxygen)has a high accuracy in assessing AP with ARDS,and can help clinicians quickly and accurately assess patients with AP with ARDS.
