Randomized Controlled Trial
Evaluation of anesthesia recovery quality after low-dose racemic or S-ketamine infusions during anesthesia with isoflurane in horses.
To compare anesthesia recovery quality after racemic (R-/S-) or S-ketamine infusions during isoflurane anesthesia in horses. ⋯ Compared with R-/S-ketamine, anesthesia recovery was better with S-ketamine infusions in horses.

Randomized Controlled Trial
Effect of remifentanil on requirements for propofol administered by use of a target-controlled infusion system for maintaining anesthesia in dogs.
To evaluate the effect of remifentanil administered by use of a constant rate infusion on the predicted plasma concentration (Cp(predicted)) of propofol required to prevent awareness in 50% of anesthetized dogs (Cp50(predicted)). ⋯ In nonpremedicated dogs, propofol Cp50(predicted) of 6.0 microg/mL may be recommended for induction of anesthesia. Propofol requirements for maintaining target-controlled infusion system-based anesthesia were reduced via infusion of remifentanil at a rate of 0.3 microg/kg/min.
