    Abstract:
    OBJECTIVE: The present study assessed and compared postoperative hypernociception and skin healing after cyanoacrylate and classic suture as well as analyzed morphologic features of the tissue repair. STUDY DESIGN: The intensity of hypernociception was measured with an electronic pressure-meter test. Rats were given an incised wound in the middle of the palms of the right and left paws. The left side was treated with a silk suture, and the right with cyanoacrylate. Control groups were treated locally with dipyrone or received a systemic pretreatment with valdecoxib. RESULTS: Cyanoacrylate was associated with less inflammation (first week), and the healing wound site was rich in collagenous extracellular matrix and neovascularization. Dipyrone in combination with cyanoacrylate greatly increased the antinociceptive effect. These results were not repeated after systemic treatment with valdecoxib, suggesting that the antinociceptive effect seen in the tissue adhesive was due to formation of a physical barrier.
