This non-comparative, multicentre clinical trial includes 43 patients whose acute or chronic wounds were treated with a new lipido-colloid dressing, Urgotul Duo, for at most 4 weeks, or until healing first occurred. The efficacy, tolerance and acceptability results obtained from this 'ready-for-use' dressing were similar to those reported for the Urgotul dressing in numerous previous clinical trials, and for all the different types of acute and chronic wounds. This well-tolerated new dressing greatly facilitates care operations in terms of execution (reduced use of supplementary gauzes for the secondary dressing) and duration (shorter nursing time), while improving patient comfort. This dressing is indicated for the local treatment of moderate exudative acute and chronic wounds in the granulation and epidermization phases.
