Clinical Overview
The Pediatric Trauma Score (PTS) was developed to address the unique physiological differences between children and adults in trauma settings. Because children compensate for blood loss differently and have different injury patterns (e.g., highly compliant rib cages), adult trauma scores often miscalculate their risk.
Pathophysiology & Evidence
The PTS heavily weights the patient's size and airway maintainability. Smaller children (<10 kg) inherently have a smaller total blood volume, making them exquisitely sensitive to hemorrhage. An unmaintainable airway or a sudden drop in systolic blood pressure (<50 mmHg) in a child represents late, catastrophic decompensation.
Formula Breakdown
PTS = Weight + Airway + SBP + CNS + Skeletal + Wounds
The score ranges from -6 to +12. A score of ≤8 serves as a highly sensitive threshold indicating the potential for multi-system trauma requiring specialized pediatric surgical intervention.
