A 28-year-old male construction worker is brought to the emergency department 45 minutes after a fall from scaffolding onto concrete. On arrival, he is alert but confused, with a GCS of 13 (E3V4M6). His pupils are equal and reactive. CT head shows a small subdural hematoma without midline shift. Blood pressure is 128/82 mmHg, heart rate 92/min, respiratory rate 18/min. After initial stabilization, what is the most appropriate next step in management?

Question

Accepted Answer

D. Admit to ICU for close neurological monitoring with serial CT scans; neurosurgery on standby. ## Management of Acute Subdural Hematoma with GCS 13 **Key Point:** A patient with GCS 13 and a small subdural hematoma without midline shift or mass effect is classified as a **moderate head injury**. The absence of neurological deterioration, pupillary changes, or significant mass effect does NOT mandate immediate surgery. **High-Yield:** Management of acute subdural hematoma depends on: 1. **Volume and mass effect** (midline shift, compression of ventricles) 2. **GCS score** (reflects severity) 3. **Pupillary status** (indicates herniation risk) 4. **Neurological trajectory** (improving vs. deteriorating) ### Decision Algorithm for Acute SDH ```mermaid flowchart TD A[Acute SDH on CT]:::outcome --> B{Midline shift OR

The patient requires ICU monitoring for at least 24–48 hours. **Mnemonic: SDHS** (Subdural Hematoma Surgery criteria) - **S**hift (midline shift present) → Surgery - **D**eterioration (GCS drop ≥2) → Surgery - **H**erniation signs (blown pupil) → Surgery - **S**mall SDH + stable → Supportive care + monitor [cite:ATLS 10th Edition, Chapter 4: Initial Assessment and Management] ![Head Injury — GCS and Management diagram](https://mmcphlazjonnzmdysowq.supabase.co/storage/v1/object/public/blog-images/explanation/4166.webp)
