Minimum anesthetic concentration of isoflurane and sevoflurane and cardiorespiratory effects of varying inspired oxygen fractions in Magellanic penguins (Spheniscus magellanicus).

The aim of this study was to determine the minimum anesthetic concentration of isoflurane (MAC) and sevoflurane (MAC) and evaluate the cardiorespiratory changes induced by varying fractions of inspired oxygen (FiO) in Magellanic penguins (Spheniscus magellanicus). Twenty adult penguins (3.53 ± 0.

Sevoflurane Sparing Effect of Morphine in Tegus (Salvator merianae) - A Preliminary Study.

This study aimed to determine the minimum anesthetic concentration (MAC) of sevoflurane in tegus (Salvator merianae) and the morphine-sparing effect on this variable. In a prospective, non-blinded, crossover study, MAC was first determined in 6 tegus under sevoflurane anesthesia alone (MAC) and then following intramuscular administration of morphine (10 mg/kg), administered 3 hour before sevoflurane anesthesia (MAC). A standard bracketing technique was applied to determine the MAC by an electrical supramaximal noxious stimulus (50 Hz, 30 mA) delivered at the base of the tail of the tegus.

The Use of Bone Marrow-Derived Stem Cells in the Treatment of a Comminuted Tibiotarsal Fracture in a Juvenile Red-legged Seriema ().

An adult red-legged seriema () presented with a comminuted fracture of the tibiotarsus and fibula. Surgery was performed, and a type II external fixator, with 2 distal and 2 proximal pins, was used to stabilize the fracture. After a 10-day stabilization period, the bird developed a second fracture on the same bone, proximal to the first fracture site.

Azaperone and xylazine: A pharmacological combination to facilitate captive deer management for red brocket deer (Mazama americana).

The care and management of deer in captivity is challenging, especially in the case of red brocket deer (Mazama americana), whose routine management using physical restraint is difficult. Our study evaluated the effects of azaperone and xylazine combination for immobilizing red brocket deer and allow for the standard capture and handling protocols (e.g.

VENOUS AND ARTERIAL ACID-BASE ANALYSIS OF MAGELLANIC PENGUINS (), AWAKE AND ANESTHETIZED BY ISOFLURANE.

This study aimed to compare the venous acid-base status of healthy awake versus anesthetized Magellanic penguins (). Ten nonanesthetized penguins were manually restrained, and a venous blood sample was collected. Six of these penguins were anesthetized by 2% isoflurane and, after an anesthetic stabilization period, both venous and arterial blood samples were simultaneously withdrawn.

Thoracolumbar epidural anaesthesia with 0.5% bupivacaine with or without methadone in goats.

Background: Epidural anaesthesia is one of the most commonly used locoregional techniques in ruminants. The lumbosacral epidural technique is reasonably easy to perform and requires low volumes of local anaesthetic drug to allow procedures caudal to the umbilicus. However, surgical procedures in the flank of the animal would require an increased volume of drugs.
