Question
NOT TRUE regarding sevoflurane
| A. |
MAC is higher than isoflurane
|
| B. |
Blood gas coefficient is higher than desflurane
|
| C. |
Potency more than isoflurane
|
| D. |

Correct Answer » C
Explanation
|
|
MAC (Minimum Alveolar Concentration)is inversely related to potency
-
- Higher MAC → Lower potency
- Lower MAC → Higher potency
Sevoflurane has higher MAC than Isoflurane, so it is less potent
C. Potency is more than Isoflurane — False
Sevoflurane is less potent than isoflurane because its MAC is higher. Hence, this statement is incorrect.
Explanation of Other Options
A. MAC is higher than Isoflurane — True
Sevoflurane (~2%) > Isoflurane (~1.15%)
B. Blood-gas partition coefficient is higher than Desflurane — True
Sevoflurane (~0.65) > Desflurane (~0.42)
D. Sevoflurane is less cardiodepressant than Isoflurane — True
Sevoflurane provides better hemodynamic stability
