Glasgow Coma scale

🧠 The Glasgow Coma Scale (GCS) is a vital score for assessing consciousness. 🚨 Remember: *changes* in GCS are often more important than the absolute number. 💡 Always describe what the patient can/can’t do rather than quoting just numbers. ⚠️ A dysphasic patient may score "1" on verbal response, but you should clarify "V1 (dysphasic)" rather than implying complete unresponsiveness. 🔒 Patients with GCS ≤ 8 are generally intubated to protect the airway and prevent aspiration pneumonitis. 👩⚕️ If GCS is reduced ➝ escalate to senior support immediately.
📖 Introduction
- The GCS is used to assess consciousness in head injury 💥, coma, and other acute brain disorders.
- It evaluates 3 domains: 👀 Eye-opening, 🗣️ Verbal response, ✋ Motor response.
- Total scores range from 3 (deep coma) ➝ 15 (fully alert).
📊 Scoring Overview
- Total GCS = E + V + M
- Severe: 3–8 ❌
- Moderate: 9–12 ⚠️
- Mild: 13–15 ✅
🔍 How to Perform
- 👀 Eye response ➝ spontaneous? to voice? to pain?
- 🗣️ Verbal ➝ oriented? confused? incomprehensible?
- ✋ Motor ➝ obeys? localises? flexion/extension?
Note: If intubated, tracheostomised, or aphasic ➝ record as V-NT (not testable).
📋 GCS Table
| Category | Response | Score |
|---|---|---|
| 👀 Eye Opening (E) | Spontaneous | 4 |
| To Speech | 3 | |
| To Pain | 2 | |
| None | 1 | |
| 🗣️ Verbal Response (V) | Oriented | 5 |
| Confused | 4 | |
| Inappropriate Words | 3 | |
| Incomprehensible Sounds | 2 | |
| None | 1 | |
| ✋ Motor Response (M) | Obeys Commands | 6 |
| Localises Pain | 5 | |
| Normal Flexion (Withdraws) | 4 | |
| Abnormal Flexion (Decorticate) | 3 | |
| Extension (Decerebrate) | 2 | |
| None | 1 |
📌 Interpretation
- 13–15: Mild head injury 😊
- 9–12: Moderate injury ⚠️
- 3–8: Severe coma ❌ ➝ airway protection needed
🏥 Usage
Used in ED, ITU, and neurology/stroke wards to assess consciousness. Helps guide airway management, neurosurgical referral, and prognosis in traumatic brain injury and other comatose states. Always compare with previous scores to identify deterioration. 📉
