Reversible immobilization of giant otters (Pteronura brasiliensis) using medetomidine-ketamine and atipamezole.

This communication reports a partially reversible chemical immobilization protocol used for translocation and veterinary care in giant otter (Pteronura brasiliensis; GO). Six GOs (three males and three females) weighing 24.8 +/- 4.

Tracheostomy in the giant anteater (Myrmecophaga tridactyla).

Anesthesia in the giant anteater (Myrmecophaga tridactyla) may be complicated by apnea. Although emergent orotracheal intubation may be possible in other species, the particular anatomy of the anteater prevents a smooth intubation. A technique, developed on a cadaver model, is described for a surgical approach to the trachea of the giant anteater that may be used to secure an airway in an anesthetized animal under emergent conditions.
