Note: Data for age are presented as mean (range). Data for height, weight, mean arterial pressure, total propofol dose, total remifentanil dose, total ephedrine dose, duration of anaesthetic, end-tidal xenon and sevoflurane, mean bispectral index value and recovery time are presented as mean ± SD. Male and American Society of Anesthesiologists classification I are shown as number (proportion). NA: Not applicable.
