Key Points
- Stabilize ABCs; begin targeted evaluation without delaying life-saving therapy.
- Use system-specific risk tools to guide testing and disposition.
- Order high-yield tests first; escalate imaging when indicated.
- Start evidence-based initial therapy and reassess frequently.
Algorithm
- Primary survey and vitals; IV access and monitors.
- Focused history/physical; identify red flags and likely etiologies.
- Order system-appropriate labs and imaging (see Investigations).
- Initiate guideline-based empiric therapy (see Pharmacology).
- Reassess response; arrange consultation and definitive management.
Clinical Synopsis & Reasoning
For Concussion Mild Tbi Ed Management, frame the differential by acuity and pathophysiology, then align diagnostics to the leading hypotheses. Prioritize stabilization while obtaining high‑yield studies such as CT Head (NC) (Hemorrhage exclusion), Glucose (POC) (Exclude hypoglycemia), MRI Brain (selected) (Ischemia/structural). Incorporate bedside imaging and targeted labs to define severity and identify complications; synthesize results with clinical trajectory to refine the working diagnosis and disposition needs.
Treatment Strategy & Disposition
Initiate disease‑directed therapy alongside supportive care, titrating to objective response. Pharmacologic options commonly include Thrombolytic (eligible), Antiepileptics. Use validated frameworks (e.g., When to Image) to guide escalation and site of care. Address precipitating factors, de‑escalate empiric therapies with data, and arrange follow‑up for monitoring and risk‑factor modification; admit patients with instability, high risk of deterioration, or needs for close monitoring.
Epidemiology / Risk Factors
- Hypertension, AF, atherosclerosis; prior stroke/TIA
Investigations
| Test | Role / Rationale | Typical Findings | Notes |
|---|---|---|---|
| CT Head (NC) | Hemorrhage exclusion | Acute blood | First-line |
| Glucose (POC) | Exclude hypoglycemia | Low | Treat promptly |
| MRI Brain (selected) | Ischemia/structural | Diffusion restriction |
When to Image
| Indicator | Plan |
|---|---|
| GCS <15 at 2 hours, skull fracture signs | CT head |
| Vomiting or age ≥65 | CT head |
| Anticoagulant use or focal deficit | CT head |
Pharmacology
| Medication | Mechanism | Onset | Role in Therapy | Limitations |
|---|---|---|---|---|
| Hypertonic saline/Mannitol | Osmotic therapy | Minutes | ICP control (selected) | Electrolyte/renal risks; ED use |
| Levetiracetam (prophylaxis) | SV2A modulation | Hours | Early seizure prophylaxis (selected) | Somnolence; ED use |
Prognosis / Complications
- Outcome tied to time-to-reperfusion; aspiration/DVT risks
Patient Education / Counseling
- Explain red flags and when to seek emergent care.
- Reinforce medication adherence and follow-up plan.
Notes
Avoid prolonged strict rest. Consider vestibular and cognitive therapy for persistent symptoms.
