Abstract

A 98-year-old man with 2 days of headache, nausea, malaise and unsteadiness was referred to the ED by his GP with a suspicion of an intracranial bleed. His medical history included atrial fibrillation (AF) (taking warfarin). Observations were SpO2 95% on air, RR24, HR88, BP210/104, GCS14, Temp 34.3. On examination he had bilateral creps and was sleepy but not confused. A septic screen was undertaken and intravenous ceftriaxone given. His CTH was essentially normal.
