title: Treatment of hypoxemia during anesthesia of brown bears (Ursus arctos).
abstract: This study assessed whether arterial oxygenation could be increased by treatment with intranasal oxygen supplementation in brown bears (Ursus arctos) with hypoxemia during anesthesia with medetomidine-zolazepam-tiletamine. Arterial blood samples were collected anaerobically from the femoral artery before and during oxygen supplementation. An oxygen flow rate of 2-5 L/min administered intranasally to brown bears weighing 12-120 kg markedly increased arterial oxygenation. Intranasal oxygen supplementation proved to be a simple and efficient method for treatment of hypoxemia in anesthetized bears.
