A 46-year-old intoxicated man was driving down the highway in the wrong direction when his vehicle struck a pickup truck head-on. He presented with a pulse rate of 130 beats/minute, blood pressure of 90/62 mm Hg, and respiratory rate of 32 breaths/minute. His pupils are 5 mm and are equally round and reactive to light bilaterally; he does not open his eyes to painful stimuli, moans with painful stimuli, and withdraws from painful stimuli. His oxygen saturation with oxygen by face mask is 86%. In addition to the possibility of traumatic brain injury, what are other important factors that can be contributing to this man’s low GCS that we need to identify and address immediately? Hypoxia Polysubstance abuse History of seizure disorder Alcohol intoxication Chronic syphilis infection
