Introduction:The aim of this study was to assess the efficacy of the Pediatric Trauma Score (PTS) in predicting significant trauma in patients presenting with blunt trauma to a high-level pediatric emergency department. Methods: Patients younger than 15 years of age presenting to the pediatric emergency department of the Tepecik Training and Research Hospital with acute high-energy blunt trauma were analyzed prospectively. The PTS was calculated on arrival at the pediatric emergency department. The patients were classified into two groups as follows: patients with a PTS of ≤8 comprised the significant trauma group, while patients with a PTS of >8 made up the non-significant trauma group. Results: Two-hundred-thirteen children with a mean age of 6.1±3.9 years (range: 10 days-15 years) were included in the study. The frequency of coagulation testing and thorax computed tomography in the pediatric emergency department, need for critical interventions and therapies in the pediatric emergency department, rate of hospitalization, need for transfer to the pediatric intensive care unit, mechanical ventilation, operation, blood transfusion, and mortality rate were statistically higher in the significant trauma group (p<0.05). PTS ≤8 exhibited a sensitivity of 56.2% and a specificity of 90.8% for hospitalization (AUROC: 0.682; 95% confidence interval: 0.610-0.755). The PTS was significantly correlated with length of hospital stay (r=-0.493; p<0.001) and length of observation in the pediatric emergency department (r=-0.442; p<0.01). Conclusion: PTS on arrival at a high-level pediatric emergency department is a good predictor of the need for critical interventions/ therapies and mortality in children with high-energy blunt trauma. However, its accuracy is moderate for the prediction of hospitalization.

Yöntemler: Akut künt yüksek enerjili travma nedeniyle Tepecik Eğitim ve Araştırma Hastanesi'ne başvuran 15 yaşından küçük çocuklar ileriye yönelik olarak incelendi. PTS yaralı acil servise geldiği anda hesaplandı. Hastalar iki gruba ayrıldı: PTS ≤8 (ciddi travma) ve PTS >8 (ciddi olmayan travma). Bulgular: İki yüz on üç çocuk (ortalama yaş: 6,1±3,9 yıl; en küçük: 10 gün -en büyük: 15 yıl) çalışmaya alındı. Acil serviste koagülasyon testi ve toraks tomografisi sıklığı, acil serviste kritik girişim ve tedavi gereksinimi, hastaneye yatış oranı, yoğun bakım gereksinimi, mekanik ventilatör gereksinimi, ameliyat, kan transfüzyonu, ölüm sıklığı PTS ≤8 grubunda daha fazlaydı (p<0,05). PTS ≤8'in duyarlılığı %56,2; özgüllüğü %90,8 (AUROC: 0,682; %95 CI: 0,610-0,755) olarak hesaplandı. PTS hastanede yatış süresi (r=-0,493; p<0,001) ve acil serviste izlenme süresi (r=-0,442; p<0,01) ile anlamlı korelasyon göstermekteydi. Sonuç: Künt yüksek en...
