All are benefits of Supraglottic airway device over Endotracheal tube except
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
It is less invasive
It causes less haemodynamic alteration
It prevents aspiration
It requires less time for inseion
