All anesthesiologists know that the brain is affected by the gases we inhale. We know that oxygen is beneficial. But is it really? We know the predominant effects of CO2 vary according to its partial pressures. But what exactly do we know about the clinical impact of these changes? We routinely administer Nitrous Oxide in the operating room. Is it really as inert as we think regarding the brain? And who ever heard that Xenon and Argon may be neuroprotective. And not only in rats. After this 75 minute marathon you will never think the same of these gases....
