A comparative study of collagen granules vs conventional dressing in the management of chronic ulcer

Abstract

Background: A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic. Aim of this study the efficacy of topical use of collagen granules in wound healing.Methods: In this prospective study, a total of 60 patients were divided into two groups, according to type of dressing i.e. for group A patients collagen granules were used and for group B patients normal saline dressing was used. Collagen granules used for this study was Medfil II.Results: The Mean ulcer size at day 1 in group A was 16.29 cm2 with a SD of 6.07cm2. In Group B, the mean ulcer size at day 1 was 14.73 cm2 with a SD of 6.37 cm2. The Z value is 0.93 and p value is >0.5. This is comparable but statistically not relevant.Conclusions: The use of Collagen Granules dressing accelerated the rate of wound healing in chronic ulcers In this study authors found that the rate of wound healing was significantly better in using Collagen Granules but after 2 weeks.
