SUMMARY:
Mastectomy surgery is considered a painful and bloody procedure, being necessary and important an effective technique analgesia to decrease deep anesthetic planes.
We aimed to compare the analgesic effectiveness of the tumescence technique with the standardized technique of continuous infusion of fentanyl for mastectomy in cats. Twenty females cat with mammary tumors were selected without predilection for weight and age. In all animals were performed trichotomy at mammary chain area, cephalic and jugular veins. After 15 minutes cephalic vein were punctured and propofol induction (5 mg.kg-1) was intravenous, then tracheal intubation and anesthesia was maintained with isoflurane. The animals were randomly assigned to two groups of 10 animals. The treatments were performed without knowledge of the anesthetist who conducted the anesthetic procedure. The tumescent group (TG) received 15mL.kg-1 of tumescence lidocaine solution (0.32%) subcutaneous dose. Fentanil group (FG) received an initial bolus of 2.5 mcg/kg slow intravenous fentanyl citrate and then were maintained by infusion at a rate of 10 ml/kg/hours. The phisiological variables [heart rates (FC), respiratory rates (f), systolic arterial blood pressures (PAS), retal temperature, oximetry (SpO2), capnography (EtCO2)] and anesthetic gases expired were evaluated throughout the entire procedure. After the surgical procedure the animals had their pain scores assessed at one-hour intervals through a multidimensional scale to a maximum time of six hours. The anesthetic recovery were performed with methadone 0.3mg.kg-1 (IM) associated to meloxican 0,15 mg.kg-1 subcutaneous dose. We conclude that both anesthesia techniques were effective to promote satisfactory analgesia in the transoperative moments, however the tumescence technique showed postoperative but prolonged analgesia in cats undergoing mastectomy, without causing risk and interfering with surgical healing.
