agents that are inhaled & pass into the blood stream via pulmonary function
those medications used to permit a rapid & pleasant transition from a state of consciousness to unconsciousness, passing through the excitement or delirium stage
selectively interrupt the associative pathways of the brain
produce a decrease in pain impulse transmission
work by competing for benzodiazepine inhibitory receptor sites
sedative/tranquilizer; aides in management of POVN; may be used in combination with fentanyl citrate
neuromuscular blockade agents-depolarizing
binds to receptor sites on the muscle side of the neuromuscular junction to prevent muscle contraction
neuromuscular blockade agents - non-depolarizing
bind to receptor sites on the nerve side of the neuromuscular junction to prevent muscle contraction
neuromuscular blockade reversal
increases production of or the breakdown of acetylcholine at the neuromuscular junction
blocks the effects of acetylcholine & vagus nerve stimulation; increases heart rate; decreases bronchial & gastric secretions
nerve blockades amides & esters
blocks nerve conduction
relaxes smooth muscles of the bronchi & stimulates contraction of peripheral blood vessel wall muscles
