What are the different classification systems used to categorize bomb blast injuries?
5 answers
Blast injuries are categorized using various classification systems. The Gustilo-Anderson classification is utilized for open fractures, distinguishing between types 1 and 2 in Group 1 and types 3A, 3B, and 3C in Group 2. Additionally, injuries caused by explosions are divided into primary, secondary, tertiary, and quaternary categories, with a focus on the severity of injuries using the new injury severity score (NISS). Current scoring systems for blast injuries have limitations, such as inaccurately predicting individual mortality, the saturation effect, and lack of precision in discriminating between injury mechanisms. To enhance blast injury assessment, it is recommended to incorporate injury severity with blast mechanisms, refine injury scales, and remove saturation effects for improved management of mass casualty incidents.
