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.
