Trauma causes substantial morbidity and functional impairments among children. The aim of this study was to investigate injuries of children, type of injuries, injury severity, functional impairments and relation between functional impairments and mechanisms of severe injuries in children following trauma in war conditions. This study followed 193 children with trauma, aged 1-16 years, who were admitted and treated in a regional rehabilitation centre from 1992-1995. The degree of injury seriousness was determined according to Injury Severity Scores (ISS). Functional status was measured by means of the own functional assessment scale. Higher ISS was noted for severe injuries caused by firearms than by other means. There was significantly minor functional recovery in children with firearms severe trauma at discharge than with other types of severe injuries (t = 2.04, p < 0.05). The number of all paediatric trauma and firearms injuries decreased by length of war duration. ISS and functional status in children injured by fall at the discharge also decreased. These results show that there are direct and long-term consequences in children age, especially in children with severe traumas caused by firearms, and indicate assessment of psychosocial status of each injured child together with severity of injury.
