All true about Laryngeal mask airway (LMA) except

Laryngeal mask airway is a Supraglottic disease which can be used for ventilation but cannot form seal over glottic opening to prevent aspiration. The Laryngeal Mask Airway LMA is asupraglottic airway devicewhich sits in the hypopharynx and paially protects thelarynx from pharyngeal secretions, but not gastric regurgitation. Advantages: Easy and rapid Less invasive Better hemodynamic stability Very useful in difficult intubations Less complications requires lesser plane of Anaesthesia 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
