Trauma Scales

Injury Severity Score (ISS)
It is an anatomical scoring system to provide an overall score for trauma patients. The injury severity score is the sum of squares of the three highest abbreviated injury scale scores for injuries to different body regions (head/neck, face, thorax, abdomen, and pelvic content, extremities, and external). ISS takes values from 1 to 75, 1 being a minor injury and 75 being a lethal injury.
Glasgow Coma Scale (GCS)
It is a standard measure used to quantify level of consciousness in head injury patients. It is composed of three parameters: best eye response, best verbal response, and best motor response. The lowest GCS total would be a 3 and the best score would be 15.
