Inhaled anesthetics remain the primary pharmacologic agents for administering general anesthesia in current surgical practices. Anesthesia providers enjoy familiarity and extensive experience with these inhaled agents in the context of modern anesthesia delivery equipment. In providing anesthetic care during disasters, providers will often have access to the same technically sophisticated anesthetic vaporization and monitoring systems typical of modern, brick-and-mortar hospital facilities. For example, anesthetic care rendered after a focal mass casualty event in an urban area would likely be done with a reliable supply of pharmaceutical agents, modern anesthetic machines, modern monitors, and reliable electricity.
