Final answer:
The MOA of most IV anesthetic agents involves eliciting several key reversible effects, including immobility, analgesia, amnesia, unconsciousness, and reduced autonomic responsiveness to noxious stimuli.
Step-by-step explanation:
The mode of action (MOA) of most IV anesthetic agents involves eliciting several key reversible effects, including immobility, analgesia, amnesia, unconsciousness, and reduced autonomic responsiveness to noxious stimuli. These agents act on the brain to produce a state of general anesthesia, which entails a loss of consciousness and insensitivity to feeling or pain.
Some commonly used IV anesthetic drugs include propofol, etomidate, barbiturates like methohexital and thiopentone, benzodiazepines such as midazolam, and ketamine.
It is important to note that the exact mechanisms by which general anesthetic agents work are still debated and subject to ongoing research.
