Anesthetics Flashcards
Lidocaine MOA ?
Inhibits Na ion channels, stabilizing neuronal cell membranes and inhibiting nerve impulse initiation and conduction (amide local anesthetic)
Lidocaine BBW ?
dose-related toxicity
Lidocaine contraindications ?
Infection at injection site
Obstetrical paracervical block
Obstetrical anesthesia (0.75% INJ form)
IV regional anesthesia
Intra-articular continuous infusion
Lidocaine Major Adverse reactions ?
CNS toxicity
myocardial depression
seizures
unconsciousness
respiratory arrest
Lidocaine common adverse reactions ?
hypotension
nausea/vomiting
paresthesia
pain, non-specific
bradycardia
Lidocaine Indications ?
Local
Regional
Spinal
anesthesia
Most lidocaines for SC anesthetics offer with ?
epinephrine
The addition of EPI creates ? and is great for ?
Creates local vasoconstriction (decreases bleeding)
Great for scalp, face (except nose)
Avoid epinephrine if what is involved ?
Fingers
Nose
Penis
Toes
Low blood flow areas
** topical nitro on top of the finger if you accidentally give epi in finger
Inhalational anesthetics inhalation examples ?
Sevoflurane
Isoflurane
**sedation, pain control and paralysis ( they meet all the criteria) no other class do all three, only the inhalations do all three
lower the # the more potent it is
**
Sevoflurane MOA ?
alters neuronal ion channels such as GABA, glutamate, and glycine receptors, resulting in decreased tissue excitability
**Benzos also hit GABA
glutamate - stimulating NT , paralysis **
Sevoflurane BBW ?
NONE
Sevoflurane contraindications ?
Malignant hyperthermia hx.
Sevoflurane pregnancy category ?
B
Lidocaine pregnancy category ?
C
Sevoflurane major adverse reactions ?
malignant hyperthermia
apnea
hyperkalemia
arrhythmias
seizures
hepatotoxicity
ICP incr.
Sevoflurane major DRUG reactions ?
thioridazine - antipsychotic
dronedarone
cisapride
saquinavir
toremifene
Sevoflurane common adverse reactions ?
agitation
cough
hypotension
laryngospasm
breath holding
nausea/vomiting
Sevoflurane indications ?
general anesthesia induction
general anesthesia maintenance
Sevoflurane monitoring ?
ECG
end-tidal CO2
end-tidal sevoflurane
concentration
oxygen saturation
vital signs continuously
Propofol aka ?
Diprivan
Propofol MOA ?
induces hypnosis
**meaning sedation, does not help with pain and it does not paralyses folks **
Propofol BBW ?
none
Propofol pregnancy category ?
B
Propofol Contraindications ?
Labor and delivery
avoid abrupt W/D
Propofol major adverse reactions ?
Propofol infusion syndrome
Bradycardia
Asystole
Hypotension
Cardiac arrest
seizures
**if they unstable then this is not a good choice
but anxious and about to have shoulder reduction then prob a good choice **
Propofol drug interactions ?
Sodium oxybate
Propofol common reactions ?
resp. acidosis during weaning
injection site rxn
hypotension
involuntary muscle movements
Hyperlipidemia
Propofol indications ?
General anesthesia induction
General anesthesia maintenance
Monitored anesthesia care induction
Monitored anesthesia care maintenance
ICU sedation
Propofol monitoring ?
ECG
oxygen saturation
vital signs continuously
Renal function - cause
acidosis
Propofol patient educations ?
Propofol can cause severe drowsiness or dizziness, which may last for several hours. You will need someone to drive you home after your surgery or procedure.
Do not drive yourself or do anything that requires you to be awake and alert for at least 24 hours after you have been treated with propofol.
Ketamine aka ?
Ketalar
**beneficial for Kids and is good in cases where there is pulmonary issues cause it cause bronchial dilation but it can increase ICP ( so if trauma or brain damage it can make it worse ) **
Ketamine MOA ?
Acts on cortex and limbic receptors, producing dissociative analgesia and sedation
**kinda like PCP **
Ketamine BBW ?
incidence 12%; psychologic manifestations vary in severity from pleasant dream-like states, to vivid imagery, hallucinations, or emergence delirium; may be assoc. w/ confusion, excitement, and irrational behavior; duration usually a few hours, recurrences up to 24h post-op in few cases; no residual psychological effects;
decr. incidence in <15 yo and >65 yo
Ketamine pregnancy ?
B
Ketamine Contraindications ?
HTN
Stroke
Head trauma
Intracranial mass or
hemorrhage
Ketamine major adverse reactions ?
Respiratory depression
Laryngospasm
ICP increased
IOP increased
Hypertension
Ketamine drug interactions ?
Carbinoxamine
Cocaine topical
Doxylamine
Ketamine common rxns ?
sialorrhea - profuse saliva
BP elevated
HR elevated
anorexia
nausea/vomiting
Ketamine Indications ?
General anesthesia induction
General anesthesia maintenance
Ketamine patient education ?
This medicine may impair your thinking or reactions. You will probably not be allowed to drive yourself home after your surgery or medical procedure. Avoid driving or operating machinery for at least 24 hours after you have received ketamine.
May cause hallucinations
Ketamine monitoring ?
ECG
vital signs continuously
Ketofol - ketamine plus profolol, with both = less incidence of ?
hypoTN or HTN ?
Etomidate aka ?
Amidate
Etomidate MC use ?
MC used for intubation plus a paralytic ( succinylcholine)
