mx of malignant hyperthermia?

name 4
propofol
ketamine
sodium thiopentone
etomidate
what is best in an haemodynamically unstable pt
to induce anaesthesia?
Ketamine
NMDA receptor antagonist
propofol
GaBA receptor agonist
rapid onset of anaesthesia
pain
rapid metabolism
moderate MI depression
post op thromboprophylaxis mx?
LMWH started 6-12 hours after surgery
example of a LMWH?
enoxaparin
when would unfractionated heparin be used over LMWH?
in VTE prophylaxis?
CKD
what drugs slow bone healing?
steroids
NSAIDs
immunosuppresive
why are pts with myasthenia gravis sensitive to non depolarising agents?
antonism of acetylcholine receptors
which anaesthetic agent has inherent anti emetic properties?
propofol
GABA receptor agonist
> effects on serotonin receptors
local anaesthetic toxicity reversal?
IV 20% lipid emulsion
muscle relaxants
suxamethonium
atracurium
vecuronium
pancuronium
managing anticoagulation post op
warfrain
stop warfarin but give treatment dose LMWH to address clotting needs
total parenteral nutrition
central vein> subclavian line
what does parenteral mean?
adminstered outside of the mouth
strongest analgesic effect?
ketamine
which anaesthetic agent is hepatotoxic?
halothane
surgically sited feeding tube?
feeding jejunostomy
post op wound cleaning
48 hours?
sterile saline
why is NO with pneumothorax bad?
high risk of tension pneumothorax as NO may diffuse into gas filled body compartments and increase in pressure
severe side effect of etomidate
adrenal suppression
