Induction agents: amnestic, hemodynamically stable
|
Benzodiazepines
|
|
Use caution with induction when using narcotic technique plus benzodiazepines as induction doses of benzodiazepines may produce profound :
|
Peripheral vasodilation and hypotension
|
|
K release, rapid onset/recovery, may cause dysrhythmias (bradycardia/tachycardia, extrasystoles)
|
Succinylcholine
|
|
Short-intermediate acting, hemodynamically stable
|
Rocuronium
|
|
Intermediate acting, very hemodynamically stable
|
Vecuronium
|
|
Tachycardia (vagolytic) greatest with volatile technique, long acting
|
Pancuronium
|
|
Histamine release, extra-hepatic/renal metabolism
|
Atracurium
|
|
No histamine release, Hoffman elimination
|
Cisatracurium
|
|
All volatile agents cause:
|
Myocardial suppression
|
|
_____ can cause tachycardia, so it is not usually the volatile chosen (but this is usually at high doses)
|
Des
|
|
Volatile may be used at ½ mac or less just to keep the pt ______, then a lot of narcotic is used
|
Amnestic
|
|
Inhalation agent that is a negative in-otrope, decreases O2 supply and demand, may produce ischemia (controversial), increases gas volume in closed spaces
|
N2O
|
|
Decrease both O2 supply and demand, decrease contractility, decrease SVR
|
Volatile agents
|
|
Hemodynamically stable but do not provide amnesia or muscle relaxation, may delay awakening, requires p/o ventilations
|
High dose narcotics
|
|
High supply, high demand when used without hypnotic/amnestic
|
Narcotic
|
|
Reasonable indicator of LV filling in the presence of good LV function, the absence of PHTN, or presence of MV disease
|
CVP
