Introduction Venous leg ulcers are an important problem in public health due to their high prevalence and treatment cost The gold standard therapy is the compression bandage Addition of different substances to the compression therapy in order to accelerate ulcer healing has been attempted but none of them has yielded optimal results
Objective To describe the treatment efficacy of venous leg ulcers treated with triple compression bandage and chitosan gel
Methods A longitudinal and descriptive study was conducted in a sample of 16 patients with 26 venous leg ulcers that were treated with triple compression bandage plus a chitosan gel every seven days during nine weeks Ulcer surface was measured during each treatment step
Results At the end of the treatment period 89 percent reduction of the ulcer area was found when compared to the initial area at the beginning of the study This value represents a reduction rate of 1 8 cm(2)/week
Discussion The results obtained in ulcer healing were higher than those previously reported when the compression bandage treatment of venous leg ulcers was performed alone The observed difference might be due to the effect of the chitosan gel
