The aim of the study was to define the principal and additional characteristics of critical burns and to evaluate the effect of an increasing Abbreviated Burn Severity Index (ABSI) on mortality in burn patients admitted to the Department of Burns and Reconstructive Surgery, University Hospital in Brno.

MATERIAL AND METHODS:
This retrospective monocentric study included all patients older than 18 years with critical burns involving more than 40% of the total body surface area (TBSA) who were admitted to the Department of Burns and Reconstructive Surgery, University Hospital in Brno, in the period from January 1, 2001 to December 31, 2010. The epidemiological data evaluated included: age, gender, size of burn injury, mechanism of injury, required surgical intervention, mortality, length of hospital stay and the presence of inhalation injury. The results were statistically analysed.

RESULTS:
A total of 2 479 adult patients were admitted to the Department in the period under study, and 112 (4.5%) of them had critical burns. In this patient group, the average age was 48.7 years, the average burned surface area was 62.8% TBSA, and the average length of hospital stay was 37.2 days. The male-to-female ratio was 2.39:1. Inhalation injury was diagnosed in 92 patients (82.1%). Of the 112 patients with burn injury, 59 died (52.7%). The lowest mortality rate was in the age category of 31 to 40 years (21.1%) and the highest rate in the patients aged over 71 years. No patient with the ABSI ≤ 8 died while, amongst the patients with the ABSI ≥13, the mortality rate was 87.8%.

DISCUSSION:
No study dealing comprehensively with this topic in a patient group of this size has so far been published in the Czech Republic. Our results showed that the patients with critical burns accounted for about 5% of all patients with thermal trauma. The ABSI has proved to be a valuable and reliable predictor of survival in patients with critical burns. The extent of burned area and age were risk factors affecting mortality. On the other hand, the effect of inhalation injury on mortality, as a single risk factor, is disputable because this develops with an increasing burned surface area.

CONCLUSIONS:
The most important epidemiological data on patients with critical burns were evaluated. The study shows that although the number of patients annually admitted to hospital with severe burns is still high, it has nevertheless decreased recently.
