Minimum alveolar concentration: A reconsideration
Minimum alveolar concentration (MAC), served as the vital concept for standard measure of potency for inhaled volatile anesthetic agents, has been employed in anesthetic practice for more than 50 years. A re-consideration in the connotation and influence factors on MAC is introduced in this article. MAC actually indicates “median effective dose (ED50) for immobility”, but it is at least not com...
متن کاملNimodipine decreases the minimum alveolar concentration of isoflurane in dogs.
Nimodipine is a calcium antagonist that binds with high affinity to neuronal membranes. It is a potent cerebrovasodilator and has been demonstrated also to affect neurotransmitter synthesis and release. Because patients undergoing surgery for intracranial aneurysms are frequently receiving nimodipine, the authors determined the MAC of isoflurane in six dogs before and during three infusion dose...
متن کاملBrainstem regions affecting minimum alveolar concentration and movement pattern during isoflurane anesthesia.
BACKGROUND Spinal transection or selective delivery of volatile anesthetics to the spinal cord reduces minimum alveolar concentration (MAC), whereas precollicular decerebration does not. The authors sought to determine which brainstem regions influence anesthetic requirements and movement responses with isoflurane. METHODS Movement (biceps femoris electromyogram) and MAC were measured in adul...
متن کاملThermoregulatory thresholds for vasoconstriction in patients anesthetized with various 1-minimum alveolar concentration combinations of xenon, nitrous oxide, and isoflurane.
BACKGROUND Nitrous oxide limits intraoperative hypothermia because the vasoconstriction threshold with nitrous oxide is higher than with equi-minimum alveolar concentrations of sevoflurane or isoflurane, presumably because of its stimulating actions on the sympathetic nervous system. Xenon, in contrast, does not cause sympathetic activation. Therefore, the authors tested the hypothesis that the...
متن کاملMinimum alveolar concentration of halothane: an ethnic comparison.
The minimum alveolar concentration (estimate of spread) of halothane which was determined in 42 Chinese, Nepalese or European patients was found to be 0.70% (0.66-0.74%) in Chinese and 0.70% (0.65-0.76%) in Nepalese and 0.68% (0.65-0.72%) in Europeans, using the Spearman Kärber method of analysis. This preliminary trial suggests that there is no ethnic difference in the minimum alveolar concent...
