MOA of general anesthetics
|
Most are thought to act at GABA-A receptor – chloride channel
|
|
Inhaled anesthetic with a low blood/gas partition coefficient
|
Nitrous oxide
|
|
Inversely related to potency of anesthetics
|
MAC
|
|
Inhaled anesthetics metabolized by liver enzymes which has a major role in the toxicity of these agents
|
Halothane and methoxyflurane
|
|
Most inhaled anesthetics SE (side effect)
|
Decrease arterial blood pressure
|
|
Inhaled anesthetics are myocardial depressants
|
Elflurane and halothane
|
|
Inhaled anesthetics causes peripheral vasodilation
|
Isoflurane
|
|
Inhaled anesthetic that may sensitize the myocardium to arrythmogenic 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
|
nitrous oxide
|
|
Fluoride released by metabolism of this inhaled anesthetic may cause renal insufficiency
|
Methoxyflurane
|
|
Prolonged exposure to this inhaled anesthetic may lead to Megaloblastic anemia
|
Nitrous oxide
|
|
Pungent inhaled anesthetic which leads to high incidence of coughing and vasospasm
|
Desflurane
|
|
DOC for malignant hyperthermia that may be caused by use of halogenated anesthetics
|
Dantrolene
|
|
IV barbituates used as a pre-op anesthesia
|
Midozolam
|
|
Benzodiazepine receptor antagonist, it accelerates recovery from benzodiazepine overdose
|
Flumazenil
|
|
This produced “dissociative anesthesia” is a cardiovascular stimulant which may increases intracranial pressure and hallucinations occur during recovery
|
Ketamine
|
|
Opioid associated with respiratory depression, but it used in high risk patients who may not survive full general anesthetia
|
Fentanyl
|
|
State of analgesia and amnesia produced when fentanyl is used with droperidol and nitrous oxide
|
Neurolephanesthesia
|
|
Produced both rapid anesthesia and recovery, has antiemetic activity and commonly used for outpatient surgery, may cause marked hypotension
|
Propofol
|
