Q: Question: Is protection of hearts from reperfusion injury by propofol associated with inhibition of the mitochondrial permeability transition?
Answer: Propofol confers significant protection against global normothermic ischaemia and during cold cardioplegic arrest. This effect is associated with less opening of mitochondrial MPT pores, probably as a result of diminished oxidative stress. Propofol may be a useful adjunct to cardioplegic solutions in heart surgery.
A:
yes
