28
Q

Ketamine MOA

A

Ketamine is a non-competitive NMDA receptor antagonist that blocks glutamate. Low doses produce analgesia and modulate central sensitization, hyperalgesia, and opioid tolerance. Reduces polysynaptic spinal reflexes.

29
Q

Lidocaine MOA

A

As a sodium channel blocker, lidocaine decreases the duration of the action potential by shortening the period of repolarization.

30
Q

Magnesium Sulfate MOA

A

The precise mechanism of action of magnesium sulfate is not entirely clear. It appears to alter membrane potential, slowing conduction and relaxing smooth muscle.

31
Q

Midazolam MOA

A

Like other benzodiazepines, MIDAZOLam intensifies the activity of gamma aminobutyric acid, the major inhibitory neurotransmitter in the central nervous system. This action is believed to result in hyperpolarization of neuronal cells, which then take longer to reach threshold and depolarize.

32
Q

Phenylephrine MOA

A

Agonizes alpha-adrenergic receptors producing arterial vasoconstriction.

33
Q

Amiodarone Indications

A

VF. pVT, unstable VT, Recurrent VT following cardioversion

34
Q
