RELATO DE CASO: TÉCNICA TUMESCENTE EM BOVINO PARA REALIZAÇÃO DE DESVIO LATERAL DO PÊNIS

Abstract

A NDB bull weighing 350kg underwent a ruffian preparation by penis lateral deviation technique at the Veterinary Hospital of the University UFRB. As premedication (MPA), 2% xylazine (0.05 mg/kg) was administered intramuscularly and a tumescent solution was used for local anesthesia. Approximately 10 minutes after administration of MPA, the animal was removed from the trunk and placed in the right lateral decubitus position, with subsequent trichotomy and antisepsis of the region to be surgically treated. The anesthetic solution consisted of 500 mL Ringer lactate, 1 mg epinephrine and 20 mL 2% lidocaine without vasoconstrictor. The entire solution was administered in the subcutaneous tissue by infiltrative technique, covering the area to be incised. After the anesthetic blockage around the foreskin and penis attachment site, the incision of the skin and subcutaneous tissue was performed. Approximately 0.5 cm of skin was removed from the new site to be implanted at a 45° angle, and the skin was sutured with Wolff stitches of non-absorbable material. The Tumescent Anesthetic Technique (TAT) was performed successfully since the animal had a good recovery without adverse effects. As described in the literature, the incised areas showed a tiny amount of bleeding. Its analgesic effect could also be observed postoperatively by the animal behavior and ease when cleaning the wound. The physiological parameters (HR 58 ± 2 and f 22 ± 4) were within normal limits for the species at surgery, remaining constant until the end of the procedure. It is possible that TAT could become an anesthetic technique widely used in cattle, since it is efficient, promotes analgesia and local anesthesia of large areas, it is easy to use and low cost.
