Background: Tissue adhesives have been widely used for wound closure, especially in children, because they are painless, fast, and easy to use and result in minimal scarring.
Objective: To analyze the biocompatibility of an adhesive based on n-butyl-cyanoacrylate in the subcutaneous tissue of rats.
Materials and methods: Two surgical sites were prepared (approximately 3 cm apart): one on the left side of the animal and the other on the right side); polyethylene tubes were implanted in each surgical site. The tube on the left was filled with n-butyl-cyanoacrylate (treated group) and the tube on the right side was unfilled (control group). After 7, 30, and 120 days, the animals were killed, and the specimens were processed for histologic analysis.
Results: No significant inflammatory reaction occurred in the treated group, showing results similar to the control group.
Conclusion: This adhesive based on n-butyl-cyanoacrylate is biocompatible in the subcutaneous tissue of rats.
