Intubation is a common medical procedure where a flexible plastic tube is inserted into the throat to aid breathing during anesthesia or an airway emergency. It can be performed through the nose or mouth and is used to open the airway, remove blockages, or help breathing. While most people recover quickly with no effects, risks include sore throat, damage to tissues, infection, or rare cases of PTSD. People should discuss risks with their doctor before any planned intubation.
