Anesthesia goal
To make insensible or without feeling
Four stages of anesthesia
Stage I - Stage of voluntary movement
Stage II - Stage of delierium or involuntary movement
Stage III - surgical anesthesia
Stage IV - CNS extremely depressed and respiration ceases
Common molecule of inhalant anesthesia
Fluorine
Stage 1 of anesthesia
voluntary movement, drug admin to loss of consciousness
Stage 2 of anesthesia
stage of delirium/involuntary movement, loss of voluntary control (excitement stage)
Stage 3 of anesthesia
surgical anesthesia, unconsciousness w/progressive depression of reflexes.
Has different planes, want to stay b/w planes 2 - 3 for most surgeries
Stage 4 of anesthesia
CNS extermely depressed and respiration ceases
Surgical anesthesia stage
Stage III
Blood/gas coefficient
anesthetic likes being in the blood, diffuses to brain slower
A low blood/gas coefficient means
will diffuse to the brain faster
Increase cardiac output has what effect on anesthesia
decreases conduction. Blood moving too fast to diffuse
What value of BG coefficient diffuses faster
1
MAC
minimum aveolar concentration
Potency of anesthesia is
1/MAC
Drugs with _______ MAC are more potent
low MAC
Isofluorane has lower MAC than Sevo so it is _____ potent
more potent
Iso induction is ______ even though it is more potent, because
slower
increased BG PC.
Difference between Sevo and Iso effects
Sevo produces Compound A - nephrotoxic
The rise in alveolar concentration toward inspired concentration is
most rapid with least solubel anesthetic
Sevo has lower BG PC is it
reaches equilibrium/brain faster
A drug with low BG PC is associated with
more rapid anesthetic induction and more rapid elimination of anesthetic and recovery
Minimum alveolar concentration =
ED50
Drugs with a low MAC are ______ potent than drugs with a high MAC
potent
Iso has a ______ MAC than sevo, therfore iso is ______ potent
lower
more
Inhalant anesthetics work by
inhibition of NMDA receptors
Inhalant CNS effects
reversible CNS depression
Absence of awareness
No recall of events at conscious level (amnesia)
Analgesia
Muscle relaxation
decreased motor response to noxious stimuli
