Supraglottic airway devices: more good than bad

摘要

Supraglottic airway devices (SADs) are tools designed to maintain an open upper airway. Since the classic laryngeal mask airway was introduced in the early 1980s by Dr. Brain, numerous upgraded and improved second-generation SADs, which incorporate specific features to improve the positive pressure ventilation and reduce the risk of aspiration, have been used in clinical practice. Thus, SADs have resulted in a paradigm shift in airway management in patients undergoing surgical procedures under general anesthesia.
