A 34-year-old man was referred to our hospital for management of multiple trauma in consequence of a car accident. Initial examination showed mild intracranial hemorrhage proven by computed tomographic scan (CT) of the brain and multiple fractures of face and thigh. Surgical repair of the multiple fractures was undertaken with stable vital signs and neurological condition. Anesthesia was induced with fentanyl and thiamylal and rocuronium was used to facilitate oroendotracheal intubation. Sevoflurane in a mixture of oxygen and air and rocuronium were used for maintenance of anesthesia and surgical relaxation, respectively. The surgeon decided to perform fixation of facial bone first, so he infiltrated the nasal mucosa with epinephrine solution to minimize blood loss. After the operation was completed, the surgeon routinely checked both pupils and found that the left pupil was fully dilated without light reflex. In fear of exacerbation of the existing intracranial hemorrhage with progressive bleeding, the operation was hastily brought to an end. An urgent CT of the brain was immediately carried out but it revealed no obvious progression compared with the preoperative examination. The patient awaked in the postanesthesia care unit (PACU) uneventfully with the left pupil returning to normal condition.
