IV Anesthetics Flashcards
IV general anesthetic
ultra-short acting barbiturate
for anesthesia conduction, increased ICP (as it decreases cerebral blood flow)
SE: dependence liability greater than benzodiazepines, acute intermittent porphyria
additive CNS depression with ethanol
POTENT INDUCER OF CYP450 ENZYMES
thiopental
methohexital, thiamylal
IV general anesthetic
short-acting benzodiazepine
increases FREQUENCY of Cl channel opening
for anesthesia induction, pre-operative sedation
SE: anterograde amnesia, unwanted daytime sedation, post-operative respiratory depression
midazolam
brotizolam, triazolam, oxazepam, etizolam, lorazepam
IV general anesthetic
highly lipophilic
for DISSOCIATIVE ANESTHESIA
SE: emergency delirium
ketamine
what can reduce emergence delirium secondary to ketamine?
pre-treatment with benzodiazepines
IV general anesthetic
for patients with limited cardiac or respiratory reserve
SE: adrenocortical suppression (impairs aldosterone production)
minimal effects on CV and respiratory functions
NO ANALGESIC PROPERTIES
etomidate
IV general anesthetic
interacts with u, o, and k receptors
SE: respiratory depression
neuroleptanesthesia achieved by combining with droperidol and NO
fentanyl
morphine, alfentanil, remifentanil
antidote to fentanyl
naloxone
IV general anesthetic for prolonged sedation SE: bradycardia, hypotension called the MILK OF AMNESIA additive effects with sedative-hypnotic drugs
propofol
fospropofol
