Self-pressurized Air Q
Brief summary
In this study investigators shall compare between the two types of air-Q 's; the Air-Q ILA blocker and the Air-Q SP with blocker , regarding good sealing and oropharyngeal leak pressure
Detailed description
The Air-Q family has introduced many improved designs, among which the Air- Q blocker intubating laryngeal airway (Air-Q ILA blocker) in 2011. It has all the previously mentioned advantages, and in addition, a new, built-in, soft guide channel that accepts regular Nasal Gastric (NG) tubes to suction or optional Blocker Tubes for accessing the posterior pharynx and managing the esophagus. investigators can suction the pharynx or suction, vent and block the upper esophagus. Ever since the idea of SAD has launched and applying an optimum intra-cuff pressure that maintains enough sealing and at the same time not injurious to the oropharyngeal mucosa concerns anesthesiologists A good seal will provide good ventilation, will guarantee the desired depth of anesthesia at lower gas flows and with lesser leaks to the esophagus, it will not cause rise in intragastric pressure thus preventing regurgitation However When the cuff pressure is more than the mucosal perfusion pressure, it is likely to either cause postoperative pharyngo-laryngeal symptoms (sore throat, dysphagia, dysphonia) or cause local mucosal trauma and nerve injuries Therefore, in 2013 another improvised design of the Air-Q family has evolved, a Self-pressurized Air Q (air-Q SP) with blocker) . It has a drain tube through which a suction tube is passed like the Air-QILA blocker , And Instead of the pilot balloon and inflating cuff, the air-Q SP with blocker incorporates a self-regulating periglottic cuff at the end of this tube, a communication orifice at the junction of the peri-glottic cuff and the airway tube. This communication between two spaces enables the cuff to dynamically regulate intra-cuff pressure depending on airway pressure. This distinguishing feature of the air-Q SP may result in reduced risk for airway morbidities related to cuff hyperinflation. In this study investigators shall compare between the two types of air-Q 's; the Air-Q ILA blocker and the Air-Q SP with blocker , regarding good sealing and oropharyngeal leak pressure

DEVICEAir-Q ILA blocker
A good seal will provide good ventilation, will guarantee the desired depth of anesthesia at lower gas flows and with lesser leaks to the esophagus, it will not cause rise in intragastric pressure thus preventing regurgitation However, When the cuff pressure is more than the mucosal perfusion pressure, it is likely to either cause postoperative pharyngo-laryngeal symptoms (sore throat, dysphagia, dysphonia) or cause local mucosal trauma and nerve injuries

Masking description
An online randomization program (http://www.randomizer.org) will be used to generate random list and to allocate patients into the study groups. Random allocation numbers will be concealed in opaque closed envelops. The patient and investigator assessing study outcomes will all be blinded to the study groups allocation.
