Elective laparoscopic ovariectomy in domestic swine (Sus scrofa domesticus)

ABSTRACT

Background: In the last years the number of exotic company animals has been increased, and the demand for neuteringservices for these animals has become greater. By the author’s knowledge, there are no records of elective ovariectomyin domestic swine (Sus scrofa domesticus). The current paper reports a case of elective laparoscopic ovariectomy in adomestic swine (Sus scrofa domesticus).Case A 4-month-old domestic swine (Sus scrofa domesticus), weighing 45 kg was referred to elective video-laparoscopicovariectomy at the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul (HCV - UFRGS). Physicalexamination and laboratory tests, including hemogram and biochemistry (alanine aminotransferase - ALT, serum albumin and creatinine), were within normal range for the species. Ketamine hydrochloride (Cetamin®) 10 mg.kg-1, xylazinehydrochloride (Xilazin®) 2 mg.kg-1, and midazolam (Midazolam®) 0.5 mg.kg-1 were administered intramuscularly (IM)as pre-anesthetic medication. The anesthetic induction was performed with intravenous (IV) propofol (Propovan®) andanesthesia was maintained with isoflurane (Isoforine®) diluted in O2 by a universal vaporizer with a partial gas rebreathinganesthetic system. Throughout the procedure, were monitoring constantly the invasive blood pressure (IBP), electrocardiogram (ECG) in lead II, peripheral arterial saturation with O2 (SpO2), end-tidal carbon dioxide concentration (ETCO2),and esophageal temperature. The abdominal cavity was accessed through the insertion of three portals (one of 10 mm ofdiameter and other two of 5 mm of diameter). The cavity was inflated with medicinal CO2 until the pressure of 10 mmHgwas achieved. The uterine body and ovaries were identified. The right ovary was suspended and, by a bipolar clamp, theovarian vessels were occluded through electrocoagulation in three distinct locations with approximately 0,5 cm betweenthemselves...
