2021-11-22 20:05:08 a motor vehicle collision. On arrival, the patient is comatose and has a Glasgow Coma Scale score of 3. His blood pressure is 110/70 mm Hg, and pulse is 114/min. Pupils are miotic, equal, and reactive to light. Ecchymosis is present behind the ear, but the remainder of the trauma survey is unremarkable. Rapidsequence intubation is performed, and the patient is mechanically ventilated. A noncontrast head CT scan demonstrates bifrontal contusions and a basilar skull fracture. One day later, a repeat head CT scan reveals diffuse cerebral edema. The ventilator respiratory rate is adjusted to achieve a PaC02 level of 26-30 mm Hg.
