anesthesia Flashcards
Meyer-overton theory
more lipid soluble=more potent
MAC
minimum aveolar concentratino
50% fail to respond.
90% of patients require >1.3 MAC
If they have pacemaker can’t use….
bovie
if use thigh turnaquit need?
general
ASA classification
1=healthy 2=- mild systemic disease 3= severe systemic disease 4.= life treatening 5=Moribund 6=organ donor
Rimifentanyl
opioid. short 1/2 life intraop or postop
metoclopramide
dopamine antagonist. antiemetic, increases gastric motility
metoclopramide (reglan)
dopamine antagonist. entiemetic. increases gastric motility
ondasteron (zofran)
5HT3 antagonist
IV antiemetic
Diazepam
benzo
anticonvulsive
meperidine
opid anticonvulsive
dantrolene
rayodine agonist
control muscle spasms and malignant hyperthermia
Nitrous oxide
analgesia. NMDA antagonist. fast acting.
Hypoxia
Halothane
anesthetic. fast acting. arrythmia. liver toxcicity. hypothermia
Sevoflurane
anesthetic faster induction and less odor
high hepatic metabolism
isoflurane
relaxant.
lowest MAC. vasodilation and bronchodilation. pungent
desflurane
relaxant fast induction and emergence
CI for smokers
vecuronium
relaxant. Ach antagonist w few CV side effects (residual muscle weakness)
CI=renal dysfunction
Midazolam
pre induction. benzo for preop seduction or induction-> over sedation (flumazenil)
Fentanyl
Pre induction. opioid for analgesia or primary anesthetic in high dose-> resp. depression
Thiopental
induction. rapid/potent-> hypotension, laryngospasm grogginess
Propofol (diprivan)
induction. groggy. high cardio and resp depression. antiemetic. allergy to egg, soy peanut
Etomidate
induction. pt. w hemodynamic instability.
CI: seizures
Ketamine
induction. amnesia w out CV depression
