ABSTRACT
The objective of this paper was to develop an experimental model to be used in the study of Transcutaneous Electrical Nerve Stimulation (TENS) on viability of random skin flap in rats. The sample was 15 Wistar-EPM rats. The random skin flap measured 10x4 cm and a plastic barrier was placed between the flap and the donnor site. The animals were submited to TENS for 1 hour immediately after the surgery and on the two subsequent days. On the seventh postoperative day, the percentage of necrotic area was measured and calculated. The experimental model proved to be reliable to be used in the study of effects of Transcutaneous Electrical Nerve Stimulation in random skin flap in rats.
RESUMO
Este artigo propõe o desenvolvimento de um modelo experimental para verificar o efeito da Estimulação Elétrica Nervosa Transcutânea (TENS) na viabilidade do retalho cutâneo randômico em ratos. A amostra constituiu-se de 15 ratos, da linhagem Wistar-EPM. O retalho cutâneo randômico foi realizado com dimensões de 10x4 cm e uma barreira plástica foi interposta entre o mesmo e o leito doador. Os animais foram submetido à TENS por 1 hora imediatamente após a operação e nos outros dois dias subseqüentes. No sétimo dia pós-operatório foram calculadas as porcentagens de área de necrose. O modelo experimental mostrou-se factível para estudo dos efeitos da Estimulação Elétrica Nervosa Transcutânea em retalho cutâneo randômico em ratos.
