摘要BACKGROUND:Despite the rapid development of pediatric intensive care medicine,there are still limited data in the literature regarding the follow-up of pediatric trauma patients in pediatric intensive care units(PICUs).In this study,we aim to evaluate our experience with children admitted and followed up with the diagnosis of trauma at our PICU.METHODS:We evaluated the retrospective data of 77 pediatric trauma patients who were admitted to the PICU at Sancaktepe Sehit Prof.Dr.IlhanVarank Training and Research Hospital from August 2020 to December 2022.The demographic data,clinical parameters and laboratory results were recorded.The primary outcome was the mortality in PICU.The performances of markers in predicting mortality were evaluated with receiver operating characteristic(ROC)curves.RESULTS:The median age of the patients was 70(33-157)months,and the median duration of hospitalization in the PICU was 6(2-11)d.Of the 77 patients,9 died due to trauma(11,1％).Among the clinical parameters,Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)Score,inotrope requirement,extracorporeal treatment requirement,and mechanical ventilator requirement were significantly higher in non-survivors than in survivors.Among the laboratory parameters,procalcitonin(PCT),lactate/albumin ratio(LAR),neutrophil/lymphocyte ratio(NLR),and transfusion requirement were significantly higher in non-survivors than in survivors.CONCLUSION:In pediatric trauma patients,baseline PCT,LAR,and NLR values can be used to identify patients at risk for mortality.
