Drug: Desflurane Anesthesia with desflurane in both Group 1 and Group 2 - adjust minimum alveolar concentration (MAC) to maintain bispectral index (BIS) between 40-60 Drug: Remifentanil Adjuvant continuous administration - adjust effect site concentration to maintain changes of vital sign below 20% Device: Ultrasonographic measurement of ONSD Procedure/Surgery: Mechanical ventilation Maintain the end-tidal carbon dioxide partial pressure between 35 and 40 mmHg and peak inspiratory pressure below 30 cmH2O. Trendelenburg position - 30 degree
