Older people, and the unwell, need less anaesthetic to reach 1 MAC, or minimum alveolar concentration. As an aside, when you're really old enough, you won't need any anaesthetic to knock you out ...

Cannabis users had significantly higher average minimum alveolar concentrations of isoflurane or sevoflurane than nonusers (mean, 0.58 vs 0.54; mean difference, 0.04; P = .021).

We randomly assigned 2000 patients to BIS-guided anesthesia (target BIS range, 40 to 60) or ETAG-guided anesthesia (target ETAG range, 0.7 to 1.3 minimum alveolar concentration [MAC]).

Background: Anesthesia machines have been developed by the application of new technology for rapid and easier control of anesthetic concentration. In this study, we used a test lung to investigate ...

However, the reduction in PAED "was marginal compared to the large difference in exposure," Nagasaka said, a difference of 1.4 minimum alveolar concentration (MAC) hours of exposure to anesthesia ...

In the 1960s, Dr. Eger helped establish what is now regarded as a universal standard for dosing inhaled anesthetics, called MAC — minimum alveolar concentration — which is used in the ...
