A new proposal to evaluate the healing of open skin wounds: volumetry Nova proposta para avaliar cicatrização de ferida cutânea aberta: volumetria

Abstract

PURPOSE: To present a new proposal to evaluate the healing of an open subcutaneous and skin wound, which we termed "volumetry". METHODS: A total of 32 circular wounds were performed in the subcutaneous tissues and skin of four feet of pigs (8 each). Each wound had about 1 cm in diameter and was 0.2 cm deep. Volume was calculated from the wound filled with saline and mass Xantopren. With the aid of a magnifying glass and local lighting, the liquid was dripped with a micropipette inside the wound until complete fullness. Volume repletion was calculated in microliters, corresponding to the volume of the wound. The mass of Xantopren was placed inside the wound to obtain a mold of the lesion. Mold volume was calculated using the formula of the volume of a cylinder closest resembling a geometric figure with mold. RESULTS: The calculation of wound volume was possible with both Xantopren and mold techniques. Volume as calculated by micropipette was 119.37 ± 30.87 microliters while the volume calculated by mold was 122.41 ± 33.90 mm3 (p=0.79). CONCLUSIONS: Volumetry in pig feet is simple and reproducible. Volumetry perfomed with saline did not differ from the volumetry with mass Xantopren. This method may be a useful tool to help evaluate the healing of open skin wounds in experimental and clinical research.OBJETIVO: Apresentar nova proposta para avaliar a cicatrização de uma ferida cutânea aberta, denominada "volumetria." MÉTODOS: Foram provocadas 32 feridas circulares cutâneas, com cerca de 1 cm de diâmetro e 0.2 cm de profundidade, em quatro patas de suíno. O volume da ferida foi calculado com solução salina e massa de xantopren. O líquido foi gotejado com uma micropipeta no interior da ferida até sua completa repleção, o que foi auxiliado com uma lupa de aumento e iluminação local. O volume de repleção foi calculado em microlitros e correspondeu ao volume da ferida. A massa de xantopren foi colocada no interior da ferida para se obter um molde da lesão. O volume do molde foi calculado utilizando-se a fórmula do volume de um cilindro que foi a figura geométrica mais parecida com o molde. RESULTADOS: O cálculo do volume da ferida foi possível com as duas técnicas propostas. O volume calculado pela micropipeta foi 119.37 ± 30.8693 microlitros e o volume calculado pelo molde foi 122.4088 ± 33.8997 mm³ (p=0.79). CONCLUSÕES: A volumetria realizada em patas de suíno é um método simples, reprodutível. A volumetria realizada com líquido não diferiu da volumetria realizada com massa de Xantopren. Esse método poderá ser útil para auxiliar na análise da cicatrização da ferida cutânea aberta em trabalhos clínicos e experimentais.
