A. Non depolarizing block
B. Depolarizing block
C. Malignant hyperthermia
D. Both depolarizing and non-depolarizing block
A. Non depolarizing block
2. Not True regarding sevoflurane:
a. MAC is higher than isoflurane
b. Blood gas coefficient is higher than desflurane
c. Potency more than isoflurane
d. Sevoflurane is less cardio depressant than isoflurane
c. Potency more than isoflurane
Minimum alveolar concentration (MAC):
This is a measure of potency. It is defined as "at stey-state, the minimum alveolar concentration of the
volatile anaesthetic that prevents reaction to standard surgical stimuli (skin incision) in 50 per cent of
subjects at sea level (1 atm).
According to MAC value:
Desflurane> Sevoflurane > Enflurane > Isoflurane > Halothane
