Análise comparativa entre dermorrafias realizadas com fio de nylon e adesivo de etil-cianoacrilato (Superbonder®) em ovinos.

Abstract

To evaluate and compare clinically and histologically the use of the adhesive ethylcyanoacrylate on repairing of skin surgical wounds, were used 5 adult sheep, clinically healthy. Were formed two experimental groups (control and treatment), each represented by one of the nasal paralumbar of each animal. For the experimental procedure, the animals were sedated with xylazine and had both nasal paralumbar anesthetized with lidocaine and two incisions were made of five centimeters into the skin in the center of each pit paralumbar. Soon after the subcutaneous dead space was reduced with plain catgut number 2-0 in standard suture in back-and-forth. The dermal suture the wounds of the control group was performed with nylon monofilament number 0, in simple pattern separately and in the treatment group with the ethyl cyanoacrylate adhesive. The wounds were evaluated daily until the tenth postoperative day as the swelling, discharge and dehiscence. For histological evaluation of healing, biopsies were taken from both experimental wounds (control and treatment groups) at 10, 20, 30 days after surgery, and each fragment was evaluated for the presence of crusts, thickening and retraction of the epidermis, fibrosis, inflammation and necrosis. The surgical procedure lasted on average 16.2 ± 1.92 minutes in the control group and 11.2 ± 2.58 minutes in the treatment group and both groups induced good healing process both macroscopically and histologically. The results showed that the ethyl-cyanoacrylate adhesive has good adhesion, and when employed in the synthesis of skin wounds in sheep, reduced the time of realization of the surgical procedure in 30,9%, not interfering with the scarring procedure and providing excellent aesthetic results without the need for removal the points.
