Effect of a topical silicone gel and a polyurethane dressing on the evolution of scars.

Objective: To assess the effectiveness and safety of a topical silicone gel (BE + Gel reductor y reparador de cicatrices) and a polyurethane dressing (BE + Apósito reductor y reparador de cicatrices) on the evolution of scars of patients who were previously recruited in the emergency care unit while seeking wound care.
Method: A single center, stratified observational, open label study was performed in the emergency care unit of Donostia Universitary Hospital (recruitment) and in the Biodonostia Health Research Institute (intervention). Scars located in unexposed body areas with the dressing, and scars located in exposed areas with either the gel or the dressing. Investigators assessed interventions at day 1 and on weeks 4, 8 and 12. Vancouver Scar Scale (VSS) and a photographical assessment were used to determine the scars evolution, and the subjective perception of the scar was evaluated by means of a questionnaire administered to the patients.
Results: Patients whose scars were treated with the silicone gel had an average initial VSS score of 5.4 ± 2.08. This value was reduced to 0.86 ± 1.17 after 90 days of treatment. Patients treated with the polyurethane dressing had an average initial VSS score of 5.8 ± 2.29. After 90 days of treatment, this average score was reduced to 0.33 ± 0.66. Positive evolution of scars was also supported by photographs and by a patient questionnaire.
Conclusions: Both treatments appear to be safe and effective, objectively, and subjectively, in the context of scar evolution.
