CPB produces changes in the blood-gas partition coefficient dependent on
the prime used and temperature. Fortunately, the overall effect for
hypothermic CPB and a crystalloid prime is only +2%. A volatile agent
started during hypothermic CPB takes longer to equilibrate and agents
already in use need to re-equilibrate, potentially changing the depth of
anaesthesia, until equilibration is complete. As these agents are
metabolized to a small degree and washout is fast, the duration of action
is not prolonged after CPB.
