Internal use of n-butyl 2-cyanoacrylate (Indermil) for wound closure: an experimental study.

n-Butyl 2-cyanoacrylate glue (Indermil) was used for the closure of dorsal wounds on rabbits. A 4-cm-long and 1-cm-wide laceration was created bilaterally on the back of 15 rabbits. One side was closed with absorbable 2-0 subcutaneous sutures and fast absorbable 3-0 skin sutures, whereas the other side was closed with cyanoacrylate glue applied on both deep and superficial tissues. A partial wound dehiscence occurred on the glue side in one animal at 2 weeks. The animal was killed at this time and considered a bad result in the glue group. In all other animals, no seroma, partial dehiscence, or wound infection occurred. Histopathologic analysis revealed that Indermil induced edema and a mild acute inflammatory reaction and resorbed almost completely within 2 months when applied to well-vascularized tissues. The application of glue on the cutaneous wound edges is a fast and easy procedure that does not seem to delay or inhibit the healing process or its quality.
