Resumo
Purpose: To analyze the in昀氀uence of occlusive dressing on the healing of excisional skin wounds in mice. Methods: Pre-clinical,
comparative, and translational study. Mice were divided into three experimental groups: wounds occluded with hydrocolloid
(HD) dressings, transparent polyurethane 昀椀lm (TF) dressings, and without occlusion (WO), monitored at three, six and 14 days,
with eight animals each. Closure rate, in昀椀ltration of neutrophils and macrophages, measurement of tumor necrosis factor-α
(TNF-α) and vascular endothelial growth factor (VEGF) and, histologically, angiogenesis were evaluated. Results: Wound closure
was accelerated in the occlusive groups. There was a decrease in TNF-α levels in the HD group when compared to the WO and
TF groups. Neutrophils accumulation decreased in the HD group. Increased dosages of macrophages were evidenced in the HD
group, compared to the WO and TF groups. Levels of VEGF were increased in the TF and HD groups. Conclusion: It is suggested
that the occlusion of wounds modulates the in昀氀ammatory response.
