ABSTRACT

Introduction: according to current researches regarding the burnt patient, it is interesting to assess the oxidative stress alterations in them to seek its link with the physiopathologic features of this nosologic entity and its possibility to establish life prognosis.
Objective: to assess the behavior of pro-oxidative and oxidative markers of patients with severe burns and to identify the possible relationship among the values of these markers with the group where the patients are located within a Cuban classification of life prognosis.
Methods: sample included 15 burnt patients, distributed in: six severe, six very severe and three critically severe, according the Cuban classification of life prognosis, determining the plasma concentrations of malonyldialdehyde, superoxide, dismutase, catalase and lipid peroxidation during the first twenty four hours, at sixth day and at twenty one days after lesion. Data were processed using the STATISTICA 6.1 program.
Results: marker's values changed the pathological way, with a significant level between each study moment. The oxidative stress in these patients appeared during the first hours after trauma and its behavior not depended on severity of patients according to the Cuban classification of the life prognosis.
Conclusions: the oxidative lack of balanced present in the burnt patient covers from the phase of hypovolemic shock up to the adaptation according the Kirsbaum physiopathologic classification. The variation of the oxidative stress markers not behaves in a homogenous way in the study groups of the Cuban classification of life prognosis.
