Background This study aimed to evaluate the prognostic value of various
inflammatory markers and indices derived from complete blood counts in
predicting mortality among pediatric trauma patients admitted to the Pediatric
Intensive Care Unit (PICU).
Patients and Methods We designed a single-center retrospective study that
included 165 pediatric trauma patients in the PICU between January 2020 and June
2024.
Results Of 165 patients, 108 (69.2%) were male and the mean age of all
patients was 75.16±57.14 months. The mortality rate was found to be 5.45% (9
patients). The Lactate-to-Albumin Ratio (LAR) and Procalcitonin (PCT)
demonstrated strong prognostic performance with area under the curve (AUCs) of
0.807 and 0.745, respectively. Notably, LAR and PCT correlated well with
mortality and the duration of invasive mechanical ventilation and PICU stay. The
Systemic Immune-Inflammation Index (SIRI), Neutrophil-to-Lymphocyte Ratio (NLR),
CRP-to-Albumin Ratio (CAR), and Pan-Immune-Inflammation Value (PIV) were less
effective individually but showed potential when combined with other
indices.
Conclusion LAR, PCT, SIRI, NLR, CAR, and PIV were associated with
mortality in pediatric trauma patients, with LAR and PCT demonstrating superior
predictive value. Therefore, LAR and PCT may serve as reliable standalone
markers for identifying critically ill pediatric trauma patients at risk of
mortality.
