The Meyer-Overton rule states:
Study on!!!!
The old theory of anesthetic action suggested that anesthesia was produced by the interaction between the anesthetic agent and the
lipid bilayer
The old theory of anesthetic action suggested that anesthesia was produced by the interaction between the anesthetic agent and the lipid bilayer. Even though our understanding of anesthetic action has moved well beyond this simplistic explanation, we believe this is still critical information that you should know
Bring it on!!!
The ----- rule states that lipid solubility is directly proportional to the potency of an inhaled anesthetic
Meyer-Overton rule
The Meyer-Overton rule states that lipid solubility is directly proportional to the potency of an inhaled anesthetic. Said another way, the greater the lipid solubility, the ----- the MAC value
"lower"
This Meyer-Overton rule implies that the depth of anesthesia is determined by the number of anesthetic molecules that are ----- in the brain
"dissolved"
This Meyer-Overton rule implies that the depth of anesthesia is determined by the number of anesthetic molecules that are dissolved in the brain and not necessarily the ----- that is used
"particular anesthetic agent"
This theory implies that the depth of anesthesia is determined by the number of anesthetic molecules that are dissolved in the brain and not necessarily the particular anesthetic agent that is used. Indeed, a wide variety of ----- agents can produce anesthesia
"dissimilar"
The ----- states that all anesthetics share a similar mechanism of action, but each may work at a different site
Unitary hypothesis
The Meyer-Overton rule states:
Lipid solubility is directly proportional to potency
From the Apex question:
The ----- states that lipid solubility is directly proportional to the potency of an inhalation anesthetic. While it is true that decreased body temperature reduces anesthetic requirements, this is not the Meyer-Overton rule
Meyer-Overton rule
From the Apex question:
The ----- states that all anesthetics share a similar mechanism of action, but each may work at a different site.
Unitary hypothesis
From the Apex question:
Which theory suggests that inhalation anesthetics interact with stereoselective receptors.
Modern anesthetic theory
