|
MOA of general anesthetics
|
act at GABA-a receptor- chloride channel
|
|
|
inhaled anesthetic with a low blood/gas partition coefficient
|
NO
|
|
|
inversely related to potency of anesthetics
|
minimum alveolar anesthetic concentration
|
|
|
inhaled anesthetics metabolized by liver enzymes which has a major role in toxicity of these agents
|
halothane and methoxyflurane
|
|
|
most inhaled anesthetics SE
|
decreased arterial BP
|
|
|
inhaled anesthetics are myocardial depressants
|
enflurane and halothane
|
|
|
inhaled anesthetic causes peripheral vasodilation
|
isoflurane
|
|
|
inhaled anesthetic that may sensitize the myocardium to arrhythmogenic effects of catecholamines and has produced Hepatitis
|
Halothane
|
|
|
Inhaled anesthetic, less likely to lower BP than other agents and has the smallest effect on respiration
|
NO
|
|
|
fluoride released by metabolism of this inhaled anesthetic may cause renal insufficiency
|
methoxyflurane
|
|
|
prolonged exposure to this inhaled anesthetic may cause megaloblastic anemia
|
nitrous oxide
|
|
|
pungent inhaled anesthetic that leads to high incidence of coughing and vasospasm
|
desflurane
|
|
|
DOC for malignant hyperthermia that may be cause by use of halogenated anesthetics
|
dantrolene
|
|
|
IV barbiturate used as a pre-op anesthetic
|
thiopental
|
|
|
benzodiazepine used adjunctively in anesthesia
|
midazolam
|
|
|
benzodiazepine receptor antagonist, it accelerates recovery from benzodiazepine OD
|
flumazenil
|
|
|
produces "dissociative anesthesia", is a cardiovascular stimulate which may increase ICP, hallucinations occur during recovery
|
ketamine
|
|
|
opioid associated with respiratory depression but is used in high risk patients who may not survive full general anesthesia
|
fentanyl
|
|
|
state of analgesia and amnesia produced when fentanyl is used wiith droperidol and NO
|
neuroleptanesthesia
|
|
|
produces both rapid anesthesia and recovery, has antiemetic activity and commonly used for outpatient surgery, may cause marked hypotension
|
propofol
|
