Inhalational Anesthesia Flashcards
Currently approved inhalational anesthetic gas?
Nitrous oxide
Currently approved inhalational anesthetic liquids?
isoflurane, sevoflurane, desflurane
What hypothesis says that the lipid solubility of a drug determines its activity/potency/MAC?
Myer-Overton Hypothesis
relief of pain without intentional production of altered mental state (may be secondary)?
analgesia
decreased apprehension with no change in level of awareness?
anxiolysis
Protective reflexes maintained; independent maintenance of airway/O2 sat/ventilation; response to verbal or physical stimulation?
conscious sedation
profound effects with loss of 1 or more of the components maintained in conscious sedation?
deep or unconscious sedation
sensory, mental, reflex and motor blockade; concurrent loss of all protective reflexes?
general anesthesia
volatile inhalational agents?
isoflurane, sevoflurane, desflurane
what ion are added to the volatile agents to prevent the compound from being explosive?
flouride
in a mixture of gases, the partial pressure or tension is proportional to what?
the concentration in overall mixture
percentage of drug in admixture X atmospheric pressure
partial pressure
what is a measurement of potency for inhalational anesthetics?
minimum alveolar concentration
what is an incomplete anesthetic?
N2O
the lower the blood:gas coefficient, the … the drug will take effect
faster
