Resumo
Foi descrita a hemi-ovariossalpingohisterectomia em cinco pacas prenhes mantidas em cativeiro no Setor de Animais Silvestres da Faculdade de Ciências Agrárias e Veterinárias (FCAV-UNESP) de Jaboticabal, São Paulo, Brasil, a fim de observar futura prenhez no corno restante. A tranqüilização foi obtida após aplicação de azaperone (4mg/kg) seguida da aplicação de sulfato de atropina (0,06mg/kg) e da associação de cloridrato de quetamina (20mg/kg) e cloridrato de xilazina (1,5mg/kg), ambos na mesma seringa, para indução da anestesia. A anestesia geral foi obtida mediante inalação de halotano por máscara. Por meio de laparotomia mediana, foram retirados o corno uterino prenhe, o ovário e a tuba uterina, todos do mesmo antímero. Antibióticos (30.000UI/kg de três penicilinas e 12,5mg/kg de duas estreptomicinas) e analgésico (0,02mg/kg de buprenorfina) foram aplicados imediatamente após a cirurgia, sendo repetidos após dois dias. Todas as aplicações foram feitas por via intramuscular. Apesar da permanência de apenas um ovário após a cirurgia, nova prenhez ocorreu no corno restante nas cinco fêmeas submetidas à cirurgia, com o nascimento de filhotes (apenas um por parto) após 215, 248, 276, 302 e 310 dias da hemi-ovariossalpingohisterectomia.
The hemiovarysalpingohysterectomy in five captive pregnant pacas kept on the Wild Animal Section at the College of Agricultural and Veterinarian Sciences (FCAV-UNESP) in Jaboticabal, São Paulo, Brazil, was conducted aiming at verifying the further occurrence of pregnancy on the remaining uterine horn. The tranquilization was achieved by using azaperone (4mg/kg) and consequent application of atropine sulphate (0.06mg/kg) and the association of ketamine (20mg/kg) and xylazine (1.5mg/kg) cloridrates, on the same syringe, for induction of anesthesia. The general anesthesia was performed via a face mask with halothane. By means of median laparotomy, the uterine horn with the fetus, the ovary and the uterine tube, all from the same antimere, were taken out. Antibiotics (30,000IU/kg of three penicillins and 12.5mg/kg of two streptomycins) and analgesic (buprenorfine 0.02 mg/kg) were injected immediately after surgery and repeated after two days. All injections were made intramuscularly. In spite of the permanence of only one ovary after surgery, new pregnancy occurred in the remaining uterine horn in the five females which went through surgery, and the birth (solely one by delivery) happened 210, 248, 276, 302 and 310 days after the hemiovarysalpingohysterectomy.
