Ml. Dvorkin et W. Bradley, THE USE OF A FOAM ANESTHESIA DONUT FOR THE POSITIONING OF A PATIENT IN THE BARBER CHAIR POSITION, Orthopedics, 18(3), 1995, pp. 277-278
The foam anesthesia donut proves quite useful in the positioning of th
e patient in the barber chair position, By placing the donut an 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 secu
red to the ring, protecting it from disconnection during surgery, The
inner foam of the donut, which is removed when applying to the face, a
lso can be used to pad the ulnar nerve at the elbow.
