Awake Craniotomy with Language Mapping

A 43-yr-old, 120 kg man, American Society of Anesthesiologists physical status 2, is being given local anesthesia with monitored anesthesia care (MAC) for an awake craniotomy. His history includes previous surgery under general anesthesia for resection of an astrocytoma. He presented with severe seizure disorder, mainly caused by further growth of the cerebral tumor. He is very nervous about having this procedure awake. Initially, remifentanil, and propofol infusion with local anesthesia provided adequate operating conditions. All sedation is turned off during the language mapping because the patient needs to be fully alert and cooperative. The patient is now only minimally sedated. Because his face is covered with drapes, he complains of severe claustrophobia and serious lack of air. His SpO2 is 100%. Despite increasing the nasal oxygen to 10 liters/min and providing 15 liters/min of oxygen around his face from the absorber circuit of the Narcomed 2B anesthesia machine, no symptomatic relief is seen. Further sedation is not indicated because he needs to follow commands during the language mapping. His complaints are now becoming so serious that he wants the mapping and surgery stopped. Besides inducing general anesthesia, is there anything else that you could recommend?
