Anesthesia will be induced with fentanyl-citrate (3µg/kg) and propofol (dose determined by automated system based on continuous BIS feedback from the patients). Atracurium besylate 0.5-mg/kg will be given to facilitate placement of airway device. Propofol administration rate will be controlled by a feedback loop facilitated by BIS monitoring using the closed-loop anaesthesia delivery system (CLADS). A BIS value of 50 will be used as the target point for induction and maintenance of GA. Intraoperative ventilation will be instituted through a polyvinyl chloride (PVC) ETT (Portex, Smiths Medical ASD, Inc, Minneapolis, USA). The size of the tube will be standardized for the male (7.5 mm ID) and the female (6.5 MM ID).

A BIS value of 50 will be used as the target point for induction and maintenance of GA. intraoperative ventilation will be maintained with PLMA (Telefex Medical, Westmeath Ireland) whose size would be selected based on body weight. In patients weighing 30-50 kg PLMA # 3.0, 50-70 kg PLMA # 4.0, and 50-100 kg PLMA # 5.0 will be inserted.
