The insertion of a flexible plastic tube through the mouth or nose into the trachea to maintain an open airway and enable mechanical ventilation. This procedure is essential for general anesthesia and treating respiratory failure.
From Greek 'endon' meaning 'within' + 'tracheia' meaning 'rough artery' (the trachea) + Latin 'in' + 'tubus' meaning 'tube.' The modern technique developed in the early 20th century, revolutionizing anesthesia and emergency medicine by providing secure airway control.
Endotracheal intubation transforms a potentially fatal airway emergency into a manageable situation in under 60 seconds! The laryngoscope used for the procedure has remained essentially unchanged since the 1940s because the original design was so perfect for visualizing the vocal cords.
