G.S., a 56-year-old woman, was involved in a motor vehicle accident; a car drifted left of the center line and struck her head-on, pinning her behind the steering wheel. She was intubated immediately after extrication and flown to your trauma center. Her injuries were extensive: bilateral flail chest, right hemothorax and pneumothorax, fractured spleen, multiple small liver lacerations, open fractures of both legs, and a cardiac contusion. She was taken to the operating room for repair of her injuries. There she received 36 units of packed red blood cells, 20 units of platelets, 12 units of fresh frozen plasma, and of lactated Ringer's solution. G.S. was admitted to the ICU postoperatively, where she developed acute respiratory distress syndrome (ARDS).
After a 3-week stay in ICU, G.S. is being transferred to your unit. The ICU nurse gives you the following report: "She is awake, alert, and oriented to person and place. Both legs remain cast from hip to toe. She can wiggle her toes on both feet. Heart tones are clear, last vital signs were 138 / 90,88,26,99.3 C); bilateral radial pulses . All the surgical incisions are healed. She has bilateral chest tubes to water suction with closed drainage, both dressings are dry and intact. She has a duodenal feeding tube, a Foley catheter to the down drain, and a left double-lumen PICC line. Urine output is good; urine is clear yellow. Her morning labs are still pending."
