Failure to secure and maintain a patent airway remains one of the leading causes of anesthesia-related morbidity. Among the various airway devices available today, LMA airway management has transformed modern practice by offering a reliable, minimally invasive alternative to endotracheal intubation.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The laryngeal mask airway (LMA) bridges the gap between face mask ventilation and endotracheal tube placement making it invaluable for routine anesthesia as well as difficult airway scenarios. Its relevance extends across operating theatres, emergency rooms, ICUs and prehospital care, making it essential knowledge for anesthesia residents, emergency physicians and NEET SS aspirants.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This comprehensive guide covers everything from types of LMA and insertion techniques to airway maintenance, combi tubes and the difficult airway management algorithm with a strong clinical and exam-oriented approach.<\/span><\/p>\n<h2><strong>What is LMA in Airway Management?\u00a0<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">A Laryngeal Mask Airway (LMA) is a supraglottic airway device designed to sit over the laryngeal inlet, forming a low-pressure seal around the glottis.
