A retrospective comparison of postoperative outcomes in ovariectomised jennies (Equus asinus) treated with phenylbutazone or flunixin meglumine.

Background: Clinically, flunixin meglumine (FM) and phenylbutazone (PBZ) are preferentially selected for the treatment of visceral and musculoskeletal pain, respectively, in horses. In donkeys, there is no information to support or refute this conventional conjecture.

Objectives: To compare postoperative outcomes in a group of jennies treated with intravenous FM or oral PBZ.

Sedation with dexmedetomidine-butorphanol or xylazine-butorphanol continuous intravenous infusions during unilateral ovariectomy in standing donkeys.

Background: Intravenous infusions of alpha-2 adrenoceptor sedatives and opioids can potentially facilitate surgery in donkeys while standing. Literature on this subject matter is scant.

Objectives: Evaluation of efficacy of sedation from α-adrenoceptors (dexmedetomidine or xylazine) and butorphanol during ovariectomy in standing donkeys.

Effect of a short pre-anesthetic fast on arterial blood gas values in isoflurane-anesthetized donkeys.

This study compared arterial blood gas parameters in anesthetized adult donkeys after a 5-hour fast ( = 22) or no fast ( = 21). Donkeys were premedicated with xylazine, induced to anesthesia with ketamine and diazepam or midazolam, and maintained with isoflurane in oxygen while breathing spontaneously and positioned in lateral recumbency. Sampling occurred approximately 25 minutes after induction.
