Epidural analgesia in addax (Addax nasomaculatus).

Epidural analgesia was used 22 times in three female addax (Addax nasomaculatus). The addax were physically restrained in a drop-floor chute and sedated with acepromazine (0.14-0.34 mg/kg). Epidural analgesia was induced with 2% lidocaine (0.17-0.38 mg/kg) via a 20-ga 1-inch needle placed at the sacrococcygeal intervertebral space or the first intercoccygeal intervertebral space. Adequate analgesia was attained to allow manipulation of the reproductive tract and transvaginal ultrasound-guided oocyte collection.
