Our guest today is Dr. Keith Baker, Vice Chair of Education at Massachusetts General Hospital.  We investigate the claim that emergence from sevoflurane is substantially faster than from isoflurane. We explore rationales and discuss cost.  Connect with us @DepthAnesthesia on Twitter or email us at [email protected]. Thanks for listening!
