Figure 2. Substitution of desflurane for isoflurane during the last 30 min of a 120-min anesthetic (CROSS) did not accelerate emergence from anesthesia (response to commands and orientation; P > 0.05). Early recovery after desflurane (DES) is more rapid than after isoflurane (ISO) or after using the crossover technique. **P < 0.01 DES vs. CROSS;++P < 0.01 DES vs. ISO. Results are means +/- SD.
