Age, Minimum Alveolar Anesthetic Concentration, and Minimum Alveolar Anesthetic Concentration-Awake
Anesthesia & Analgesia, 2001 Two defining effects of inhaled anesthetics (immobility in the face of noxious stimulation, and absence of memory) correlate with the end-tidal concentrations of the anesthetics. Such defining effects are characterized as MAC (the concentration producing immobility in 50% of patients subjected to a noxious stimulus) and MAC-Awake (the concentration ...

Increasing plasma ketamine concentrations decrease the minimum alveolar concentration of isoflurane in rabbits [PDF]
Frontiers in Veterinary ScienceTo evaluate the effects of increasing plasma ketamine concentration on isoflurane minimum alveolar concentration (MAC) in rabbits, six New Zealand white rabbits weighing 4.21 ± 0.35 kg were anesthetized with isoflurane in oxygen.

Anesthesia & Analgesia, 1998 We evaluated the effects of i.v. adenosine triphosphate (ATP) on sevoflurane minimum alveolar anesthetic concentration (MAC) and MAC-Awake. The study group included healthy patients 20-60 yr of age. The study groups for MAC-Awake determination included 49 patients who were scheduled for elective surgery.

Effects of lidocaine, dexmedetomidine or their combination on the minimum alveolar concentration of sevoflurane in dogs. [PDF]
J Vet Med Sci, 2014 The aim of this study was to determine the effects of lidocaine (LIDO) and dexmedetomidine (DEX) or their combination (LIDO–DEX), administered by constant-rate infusion (CRI), on the minimum alveolar concentration (MAC) of sevoflurane in dogs.

A study of the relationship between Bispectral index and age-adjusted minimum alveolar concentration during the maintenance phase of general anesthesia in elective surgery [PDF]
Journal of Anaesthesiology Clinical PharmacologyBackground and Aims: Bispectral index (BIS) and minimum alveolar concentration (MAC) are commonly used to monitor the depth of anesthesia. The objective was to study the correlation between BIS and age-adjusted minimum alveolar concentration (aaMAC ...

Minimum Alveolar Concentration (MAC) of Xenon with Sevoflurane in Humans [PDF]
Anesthesiology, 2001 Background Although more than 30 yr ago the minimum alveolar concentration (MAC) of xenon was determined to be 71%, that previous study had technological limitations, and no other studies have confirmed the MAC value of xenon since.
