ABSTRACT

Objective: To analyze the institutional epidemiology of injuries caused by explosions.
Setting: Third level health care hospital (Hospital Central Militar).
Design: Descriptive, retrospective, transversal study.
Statistical analysis: Relative frequency of qualitative and quantitative variables, calculation of central and dispersion measures.
Patients and method: Blast-injured victims, admitted in our trauma center from February 2004 to January 2008. Variables studied were: age, gender, nature of injury and instrument –civil or military–, type of explosive artifact, specific injury mechanism –barotrauma, blunt or penetrating– cardiac frequency at admission respiratory frequency at admission, systolic arterial pressure at admission, revised trauma scale (RTS), injury severity score (ISS); injuries and prognostic variables.
Results: Thirty-nine patients with injuries due to explosions were admitted; 92% of the lesions were due to a military artifact. The specific injury mechanism was barotrauma in 82%, and penetrating in 18%. RTS value was 6.8 ± 3.2 (0-7.84) and of 54.3 ± 29.9 (9-75) for ISS. The most affected organ was the skin (100%). Global morbidity rate was of 85%; mortality was of 41%.
Conclusion: Injuries due to explosions are not frequent; they cause a high anatomic severity index, even when patients arrive in a stable hemodynamic state.
