Prognostic Value of the Systematic Immuno-Inflammatory Index in Pediatric Blunt Abdominal Trauma Patients

INTRODUCTION: Trauma is a leading cause of morbidity and mortality in children. One in every four patients with trauma has abdominal trauma. Abdominal trauma is considered the third leading cause of death associated with trauma. Mortality increases in patients with inflammation because of the body’s reaction to trauma. The systemic immune-inflammation index (SIII) is a test indicative of inflammation in the body based on complete blood count alone. The index value may indicate prognosis in pediatric patients with blunt abdominal trauma
METHODS: The present study was designed as retrospective and single-center research. The study included pediatric patients with isolated blunt abdominal trauma who were admitted to the emergency department between June 01, 2021 and June 01, 2022 and who met the inclusion criteria. Patients’ demographic data; medical history; WBC, platelet, and neutrophil count; SIII; and outcome status were captured in the case form.
RESULTS: The study included 103 patients, of which 64.1% were male and the mean age was 7.32 ± 5.12 years. Mortality was seen in 6.8% of the cases included in the study. The sensitivity and specificity for the cutoff value of 890.47 × 103/L SIII was 95.7% and 62.5%, respectively (AUC: 0.832; 95% CI: 0.820–0.944, p < 0.003), in pediatric patients presented with blunt abdominal trauma.
DISCUSSION AND CONCLUSION: High scores from SIII, a rapid, inexpensive, reliable, and radiation-free test, could be used as a predictor of mortality in pediatric patients admitted to the emergency department with blunt abdominal trauma.
