Document Summary
Excitatory nt: dopamine (catecholamine, precursor to norepinephrine) Low = lethargy, sleep cycle, low focus // cholinergic system: glutamate. Can be depleted if too much excitation present, too much causes nausea: gaba (calming) Too much can cause sedation, fatigue, amnesia, confusion. Phenytoin (dilantin), carbamazeprine (tegretol), valproic acid: anxiety. Benzodiazepines midalozam (versed), lorazepan (ativan: psychosis (schizophrenia/mania) Fluvoxetine (prozac), sertraline (zoloft), paroxetine (paxil), citalopram (celexa) Lose ach-containing cells, buildup of amyloid deposits = plaque. Tx hypertension thru central-act mechanism: b1 agonist. Tx cardiac arrest, heart failure, shock: b2 agonist. Tx asthma, premie labour contractions: norepi (alpha+beta) // epi (alpha+beta, dobutamine (beta1) // dopamine (beta1, phenylephrine (alpha, ventolin (beta2) // serevent (beta 2) Stimulates dopamine release in cns (decreased pain sensation) Atropine (induces tachycardia), ditropan (tx bladder spasms), scopolamine (motion) s/e: dry mouth, dizziness, pupil dilation, constipation, restless. Ruronium: adjunct to ga, for rapid intubation. Ga tx goals: lose consciousness for major process, loss of pain response, loss of reflexes (neuromuscular blockers) procedure dependent.
