Abstract

Seven anesthesia events were performed over 6 wk on a 1.5-yr-old female okapi (Okapia johnstoni) being managed for a fetlock injury. A combination of butorphanol (B) (median; range) (0.045; 0.031–0.046 mg/kg), medetomidine (M) (0.037; 0.031–0.037 mg/kg), ketamine (K) (0.553; 0.536–1.071 mg/kg), and thiafentanil (T) (0.0045; 0.0040–0.0046 mg/kg) was administered in a padded stall. One dart containing all drugs was used for the first two anesthesias. Subsequently, BM was administered 10 min prior to KT using two darts. Time (median; range) from initial injection to first effects (6; 3–7 min) and recumbency (14; 4–20 min) were recorded. Induction quality with the one-dart protocol was poor or fair and was good or excellent with the two-dart protocol. Following recumbency, the okapi was intubated and ventilated, and physiological parameters were recorded. Anesthesia was consistently achieved with BMKT, but induction was smoother with the staged two-dart approach. Neither resedation nor renarcotization was observed post-reversal.
