Final answer:
It is not necessary to visualize the baby's vocal cords when inserting a laryngeal mask. The device provides an open airway differently than endotracheal intubation, which does require seeing the vocal cords. After surgery, patients often have a sore throat due to the airway devices used.
Step-by-step explanation:
In the procedure of inserting a laryngeal mask, it is not necessary to visualize the baby's vocal cords. The laryngeal mask airway (LMA) is a device that is designed to provide an open airway without the need for endotracheal intubation, which involves visualizing and placing a tube through the vocal cords.
During general anesthesia, muscles necessary for breathing and moving the tongue can relax, leading to the potential obstruction of the airway. Endotracheal intubation is one method used to ensure an open airway by inserting a tube into the trachea. While endotracheal intubation requires visualization of the vocal cords, the insertion of a laryngeal mask involves placement over the larynx without a direct view of the vocal cords.
Following surgery, the anesthesiologist will gradually wean the patient from anesthesia, allowing the muscles of respiration to begin functioning independently before removing the airway device. It is common for patients to experience a sore or scratchy throat after the use of endotracheal tubes or laryngeal masks.
