Altered mental status

HPI

43 year old white female was brought the emergency room with a one day history of altered mental status.  The evening prior to presentation her husband found her lethargic.  Her mental status deteriorated over the next 6 hours, and she was described as acting “drunk.”  She was stuporous, ataxic, and dysarthric, and vomited a few times.  There was no history of fever, chills, headache, abdominal pain, or dysuria.

She has had three similar episodes in the past six months during which she rapidly improved with fluid, electrolyte, and bicarbonate supplementation.

PMH
  1. Small and large bowel infarction-In January of 2002, she had an extensive bowel infarction from her jejunum to the splenic flexure of her colon that was  attributed to use of oral contraceptives.  She was left with 80cm of small bowel that was secondarily reanastomosed to her descending colon.  She has suffered from short bowel syndrome since the resection and has 12-15 watery bowel movements daily
  2. Deep venous thrombosis and pulmonary emboli-She developed a lower extremity deep venous thrombosis complicated by pulmonary emboli during the post-operative period after the bowel resection.  An inferior vena cava filter was placed; a hypercoagulability work-up was negative.
