Orquiectomia em cavalos: Comparação entre três técnicas em relação ao tempo cirúrgico, complicações pós-operatórias e tempo para alta hospitalar

Abstract

Orchiectomy is used to neuter low genetic value horses, improving management. Can be performed under general or local anesthesia, supine or quadrupedal position respectively. Some complications can occur such as bleeding, swelling, infection and peritonitis. The aim of this study was to compare the surgical time, the occurrence of postoperative complications and length of hospital care of horses undergoing elective orchiectomy through three different techniques used by veterinary school students and residents. 25 horses were selected, divided into three groups: group 1 (EMA, n=8) underwent bilateral orchiectomy in standing position, local anesthesia and sedation, hemostasis with emasculator and Tunica kept open; Group 2 (BRA, n=8), underwent bilateral orchiectomy in standing position, local anesthesia and sedation, hemostasis with two 2.5mm nylon tiewraps and Tunica vaginalis kept open; Group 3 (ING, n=9), underwent bilateral orchiectomy in supine position and general anesthesia, hemostasis with emasculator, and closure of Tunica vaginalis and skin. The mean surgical times were 16.3±2.5min in EMA, 14.5±1.6min in ARB and 64.4±16.6min in ING. There isn't postoperative bleeding in ING Group; EMA had a grade 2 bleeding and ARB had a grade 1 bleeding. The mean hospitalization time were 22.7±3.2 days in EMA, 20.75±0.7 days in BRA and 10.7 ± 4.5 days in ING. Bilateral orchiectomy under general anesthesia and closure of the Tunica vaginalis, promotes longer surgical times when compared to orchiectomy in standing positions maintaining the surgical wounds opened. However, postoperative complications in the neutered animals weren't observed with this technique, thus reducing the length of hospital stay and postoperative care.
