Inhalationsanæstetika Flashcards

1
Q

Virkningsmekanisme for inhalationsanæstetika?

A

Virker på cellemembranen eller cellemembranproteiner –> De giver en mere henflydende cellemembran –> mindsker den axonale ledning og dermed nedsætter de frigivelsen af neurotransmittere.

Man ved det ikke 100 %

Q

List olie/gas fordelingskoefficienterne for inhalationsanæstetikaerne fra lavest til størst:

Forklar hvad dette betyder for MIC og induktionshastigheden:

A
N2O 
Sevofluran
Enfluran
Isofluran
Halothan

Jo lavere Olie/Gas koefficient des højere MIC

Jo lavere Olie/Gas koefficient des hurtigere induktion
