Administração tópica de cloridrato de hidralazina na viabilidade de retalho cutâneo randômico em ratos

PURPOSE: Assess the effect of hydralazine hydrochloride, for iontophoresis, on the viability of random skin flaps in rats. METHODS: Sixty Wistar rats was randonly destributed in 4 groups (n=15), these animals was submited as randon dorsal skin flaps as cranial base with measure 10X4 cm. The animals...

Sumario:PURPOSE: Assess the effect of hydralazine hydrochloride, for iontophoresis, on the viability of random skin flaps in rats. METHODS: Sixty Wistar rats was randonly destributed in 4 groups (n=15), these animals was submited as randon dorsal skin flaps as cranial base with measure 10X4 cm. The animals from group 1 was utilized as control, in group 2 was submitted to direct current o 4mA-20' immediately after the surgery and on the two subsequent days. In group 3 the stimulation eletric simulation with hydralazine hydrochloride. In group 4 iontophorese with hydralazine hydrochloride 4mA-20'. The analysis of the results was made on the seventh day post operative and interpreted with test non parametric of Kruskal-Wallis. RESULTS: and the necrotic area stayed fixed in: group 1= 45%; group 2= 39%; group 3= 46% and group 4= 41%, being the statistical analysis did not evedenced any significant. CONCLUSION: The hydralazine hydrochloride when taken for iontophorese was not efficacious in reduce the necrotic area.
