Indications Flashcards
Benzocaine
“Short acting” ester type local anesthetics
topical
Procaine (Novocaine)
“Short acting” ester type local anesthetics
infiltration, epidural, spinal
Cocaine
“Short acting” ester type local anesthetic for topical use in throat and nose procedures – readily absorbed through mucous membrane
Vasoconstrictive properties that may help to limit systemic absorption
Lidocaine
“Longer acting” amide type local anesthetics
infiltration, Bier block, peripheral, epidural, spinal, MC used*
Ropivacaine
“Longer acting” amide type local anesthetics
peripheral
Epinephrine
Reduce systemic absorption of local anesthetics by vasoconstriction
Clonidine
Can be used in conjunction with LAs for epidural and spinal administration to further reduce pain transmission
Diazepam (Valium)
Treat convulsions due to systemic absorption of LA into CNS
Nitrous Oxide advantages
Can be useful as analgesic used 70-80% NO in O2
Rapid induction/recovery
Little toxicity
Analgesia before anesthesia
Isoflurane advantages
CO maintained, systemic vessels dilate causing small ↓ in BP, potent coronary vasodil and arrhythmias are uncommon
Sevoflurane advantages
Can be used for outpatient anesthesia because of rapid profile
Desflurane advantages
Useful for outpatient surgery due to rapid onset and recovery
Propofol advantages
Rapid metabolism and recovery
Little accumulation
“Milk of amnesia” → hypnotic and forgetful rest
Etomidate advantages
Antagonist available (if OD this is good to have)
Anterograde amnesia
Cardiovascular stability → used for pts at risk of hypotension
Ketamine advantages
Analgesia
No respiratory depression but may ↑ BP
Hypnotic state- dissociative anesthesia (somewhat aware of surroundings not amnesia)
Adverse effects less common in children
Benzodiazepines
anxiety
↑ amnesia
Diphenhydramine
Prevent allergic rxn + sedation
Ondansetron
Prevent aspiration of stomach contents
↓ post surgical nausea and vomiting
Opioids
analgesia
Scopolamine
Amnesia, prevent bradycardia and fluid secretion (esp in trachea)
