The foam anesthesia donut proves quite useful in the positioning of the patient in the barber chair position. By placing the donut on top of the patient's face, it protects the patient's eyes from trauma by the assistants holding retractors. The endotracheal tube also can be secured to the ring, protecting it from disconnection during surgery. The inner foam of the donut, which is removed when applying to the face, also can be used to pad the ulnar nerve at the elbow.
