After the block is performed, all subjects will receive induction of general anesthesia with fentanyl 1-2 mcg/kg, propofol 1-2 mg/kg and suxamethonium 1 mg/kg. After induction the trachea will be intubated with 7.0 mm ID endotracheal tube. For analgesia all patients will receive 1 gm of intravenous acetaminophen. Anesthesia will be maintained with sevoflurane with oxygen and air. To minimize PONV, every patient will receive ondansetron 4mg at the end of the surgery. Fentanyl 25 mcg boluses will be used as rescue analgesia intra operatively. When extubation criteria have been met the trachea will be extubated and the patient will be taken to PACU.
