A head and neck covering is cut from a flat sheet of foam material to form a body portion of the head and neck covering. The foam material has a first surface cut to form an eye region, mouth region and neck region. The foam material has a second surface opposite the first surface which is continuous other than an opening for intubation. The foam material is compliant so that the body portion conforms to contours of the head and neck of the anesthetized patient. A closure mechanism is attached to the body portion for securing the head and neck covering around the anesthetized patient. The foam material reduces a potential for trauma to the head and neck of the anesthetized patient. A plurality of channels is formed in the foam material. Warm fluid is circulated through the channels to reduce heat loss for the patient.
