Final answer:
The importance of stylet in intubation is to maintain an open airway, ensuring proper airflow to the lungs and preventing obstruction from the oropharynx.
Step-by-step explanation:
During general anesthesia, the muscles necessary for breathing and moving the tongue can relax, potentially blocking the airway. To maintain an open airway and avoid complications, the safest procedure is endotracheal intubation. This involves placing a tube into the trachea, allowing doctors to ensure proper airflow to the lungs and preventing obstruction from the oropharynx.
Intubation is commonly used during surgeries or when a person's respiratory system is blocked or injured, and it allows artificial air supply to bypass the obstructed area and reach the lungs. After the procedure, which typically takes about 30 minutes for the patient to wake up from, individuals may experience a sore throat.
