Anesthetic management
Patients were premedicated with oral midazolam syrup 0.5 mg/kg an hour before surgery. In the operating room, basic monitoring including pulse oximetry, non-invasive blood pressure cuff and 3 lead electrocardiography were connected to the patient. Anesthesia was induced with 8% sevoflurane in oxygen/air mixture (50%). A 22-gauge venous cannula was inserted to give fentanyl 1 µg/kg, after the patient became deeply anesthetized, an I-Gel supraglottic airway of appropriate size was inserted. Anesthesia was maintained with 1–2% sevoflurane in oxygen/air mixture (50%) and ventilation was assisted spontaneous ventilation. At the end of surgery, the patient received a single dose of intravenous ibuprofen infusion 10 mg/kg.
