Abstract : Trauma is a prominent cause of death in children. In this demographic, Abdominal trauma is the third greatest cause of mortality. The goal of this study was to see how accurate a new scoring system for Pediatric Abdominal Blunt Trauma (PABTS)was in evaluating the accuracy of anew scoring system for blunt abdominal trauma in babies and children. A prospective study carried out on infants and children up to the age of 16 who were referred to the emergency department with acute abdominal injuries between February 2018 and February 2021. A quick primary assessment, resuscitation of vital functions, and a more extensive secondary survey were performed on all patients. After that, we started detecting elements from the new score (PABTS), followed by the start of definitive care. 200 patients with mean age 5.954 ±.616 divided to 3 Groups according to severity of injury; Group A (106 patients) with a Score from 0 up to 10 ….. conservative management. Group B (79 patients) with a Score from 11 up to 25 ….. conservative management with CT with contrast and follow up & rescoring. Group C (15 patients) with a Score from 26 up to 35 …… operative management. Accuracy of our new score PABT Score was 96.9% with cut off ˃16. PABT Score is an applicable, easy method for prediction of truma severity in pediatric emergency and deal more vitally than other Scores like BATIC Score This would also help in evaluation for early invasive monitoring and treatment decisions in the intensive care unit.
