ABSTRACT

The main objective of wound management is to achieve healing in the shortest possible time, with a prepared surgical bed. The fastest option is to use autologous tissue in the form of a skin graft. Skin grafts are part of the reconstructive ladder that allow cutaneous coverage in defects not suitable for primary or secondary closure. We propose a new instrument for obtaining skin grafts for small wounds coverage and compare it with the electric dermatome. A non-randomized, prospective, comparative experimental study was carried out in 20 patients divided into two groups. one using the new instrument and the other using the electric dermatome. The new instrument consists of a degraphing knife. Student's t-test was used to compare means and standard deviations of quantitative variables and the χ² test for qualitative variables, with p < 0.05 of significance level. No statistically significant differences were found between the new instrument and the electric dermatome for quantitative variables such as graft thickness, harvesting time and healing quality in the first three months, pain and satisfaction. We conclude that the proposed new instrument offers advantages such as low cost, reproducibility, easy sterilization and no complications.
