<prompt> All are benefits of Supraglottic airway device over Endotracheal tube exceptIt is less invasiveIt causes less haemodynamic alterationIt prevents aspirationIt requires less time for inseion  <response>: Endotracheal tube is the best device to prevent aspiration. There is an increased incidence of aspiration of gastric contents with laryngeal mask airway. The Laryngeal Mask Airway LMA is a supraglottic airway device which sits in the hypopharynx and paially protects the larynx from pharyngeal secretions, but not gastric regurgitation. Advantages: Easy and rapid Less invasive Better hemodynamic stability Very useful in difficult intubations Less tooth and laryngeal trauma Does not require muscle relaxation Does not require neck mobility Disadvantages: Increased risk of gastrointestinal aspiration Less safe in prone or jackknife positions Less secure airway Greater risk of gas leak and pollution Can cause gastric distention
