"Induction: After pre-oxygenation with 100% oxygen, anesthesia will be induced with propofol 2mg/kg (1 ampoule contains 200 mg in 20cc syringe), 100 ml of isotonic saline over 15 minutes. Fentanyl 1 mcg/kg (1 ampoule contains 100mcg over 10cc syringe). Cis-atracurium 0.2 mg/kg (1ampoule contains 20mg in 10cc syringe) will be administered and endotracheal intubation will be done~Maintenance: Anesthesia will be maintained with Isoflurane 1-1.5 % in oxygen and air mixture 1:1, and cis-atracurium will be administered in incremental doses of 0.03mg/kg/30min. Another IV cannula will be placed with two infusion pumps of normal saline 50cc and fentanyl infusion 1-2 mcg/kg/hour (max 300 mcg total)."
