Comparing Between Air-Q Intubating Laryngeal Airway and Ambu® AuraGain™

Anesthesia is induced with sevoflurane in oxygen. The anesthesia plane is gradually deepened by increasing the inspired concentration of sevoflurane (2-8%) till the loss of eyelash reflex. After intravenous (IV) cannula is inserted and intravenous fentanyl 1mcg/kg and rocuronium 0.6mg/kg are administered. Use of neuromuscular blocking agent is to minimize the risk of reflex activation of the airway. After 3 minutes, the appropriate size (depending upon body weight) of Ambu Aura Gain is lubricated with water soluble lubricant (KY jelly) is inserted by investigator based on manufacturer recommendation with the patient's head in neutral position. The cuff then is inflated to an intra-cuff pressure of 40 cm H20, measured using a digital cuff pressure monitor.
