Traumatismo torácico: caracterización de hospitalizaciones durante tres décadas / Thoracic trauma: experience of three decades

ABSTRACT

Background: Trauma is the leading cause of death in young patients and thoracic trauma (TT) is responsible for 25-35% of trauma deaths. Aim: To describe and compare features, trauma severity indexes and morbidity of patients admitted for TT in the past three decades. Material and Methods: Review of a TT database, operative notes and medical records of patients. These were separated by decade of admission (1981-1990, 1991-2000, 2001-2010). TT characteristics were compared. Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS) were calculated. Results: A total of 3,068 TT were reviewed. In the 1981-1990 period, 604 cases of TT were registered (19.7%), in the 1991-2000 period, 1,070 cases (34.9%) and in the 2001-2010 period, 1,394 cases (45.4%) (p < 0.05). The ages of patients in each of these periods were 34.9 ± 15.5, 33.9 ± 16.2 and 35.7 ± 18.2 years respectively (p < 0.05). The proportion of patients aged 65 years or more were 6.6, 7.7 and 10.1% respectively, the proportion of females was 6.1, 9.4 and 12.0%, respectively. The causing agents per decade were knife wounds in 51.5, 61.1 and 60.0% of cases respectively, firearms in 2.5, 3.3 and 5.0% of cases respectively, multiple trauma in 13.9, 14.5 and 9.0% respectively and morbidity in 18.7, 19.7 and 11.7%, respectively. The ISS per decade was 11.9 ± 6.5, 12.9 ± 6.9 and 10.4 ± 6.8 respectively. No significant difference were found in mortality (1.5, 3.0, 2.0% respectively) or TRISS score (2.7, 3.2 and 3.8% respectively). Conclusions: An increase in the number of hospital admission for TT has occurred in the last three decades, with an increase in the proportion of admissions of subjects aged 65 years or more, females and with firearm injuries.
