Ovariohysterectomy of three vampire bats (Desmodus rotundus).

Three sexually mature female common vampire bats (Desmodus rotundus) housed at the North Carolina Zoological Park, Asheboro, North Carolina, were selected for surgical ovariohysterectomy. All animals were induced and maintained with isoflurane anesthetic gas. Magnification loop glasses were worn by the surgeon for the procedure. A ventral midline incision was made into the abdominal cavity. Simple micro-ophthalmic surgical packs along with hemoclips were used to perform the ovariohysterectomies. The linea alba and muscular layers were closed using a simple continuous suture pattern with 4-0 polydioxanone suture. The skin was apposed using a horizontal mattress suture pattern with 4-0 polydioxanone suture. Animals recovered with minimal deleterious side effects. Animals were housed together in a recovery chamber and administered meloxicam at 0.2 mg/kg placed in their blood meal once daily for 7 days postoperatively, after which they were returned to their normal enclosures.
