As feridas do membro distal equino que cicatrizam por segunda intenção, são potencialmente de cicatrização lenta. O objetivo do estudo consistiu na avaliação do efeito terapêutico do laser ou da aplicação de fibrina rica em plaquetas (PRF) na cicatrização de feridas por segunda intenção de membros distais de equinos e de etiologia traumática, em comparação com o método convencional na prática clínica. Todas as feridas (n=9) possuíram diferentes dimensões iniciais e tempos desde a sua lesão até à primeira observação clínica. Consideraram-se três grupos: o grupo controlo (pomada tópica + penso); o grupo laser (terapia do laser + penso); e o grupo PRF (PRF + penso). As feridas foram fotografadas e medidas, com posterior cálculo das suas áreas diárias (retangular e elítica) e da sua taxa de cicatrização. Na análise estatística utilizou-se o teste de variância unifatorial (one-Way ANOVA) e o teste post-hoc de Duncan, com significância de P<0,05. A taxa de cicatrização foi superior no grupo laser em relação aos grupos controlo e PRF (P<0,05), mas semelhante entre o grupo PRF e o grupo controlo. Em conclusão, este estudo preliminar sugere a continuação de trabalhos de estudo em feridas do membro distal do cavalo utilizando laser e PRF numa maior amostragem e em condições controladas.
ABSTRACT - LASER OR PLATELET-RICH FIBRIN APPLICATION ON MANAGEMENT OF EQUINE DISTAL LIMB WOUNDS - Equine distal limb wounds that are left to heal by second intention are potentially slow healing. This study evaluated the therapeutic effect of laser or the application of platelet-rich fibrin (PRF) in wound healing by second intention of distal limbs of horses and of traumatic etiology, in comparison with the conventional method in clinical practice. All wounds (n = 9) had different initial dimensions and times since their injury until their first clinical observation. Three groups were considered: the control group (topical ointment + dressing); laser group (laser therapy + dressing); and the PRF group (PRF therapy + dressing). The wounds were photographed and measured, with subsequent calculation of their daily areas (rectangular and elliptical) and their healing rate. In the statistical analysis, a one-way ANOVA and a post hoc comparison test (Duncan test) were used, with significance of P < 0.05. The healing rate was higher in the laser group compared to the control and PRF groups (P < 0.05), but similar between the PRF group and the control group. In conclusion, this preliminary study suggests the continuation of studies on wounds of the distal limb of the horse using laser and PRF therapies in a larger sampling and under controlled conditions.
