Paediatric GCS Assessment
Quick Reference
| GCS | Severity |
|---|---|
| 15 | Normal |
| 13-14 | Mild impairment |
| 9-12 | Moderate impairment |
| 3-8 | Severe impairment |
| ≤8 | Coma / Airway at risk |
Paediatric vs Adult GCS: Key Differences
Paediatric (Pre-verbal) Verbal Scale
| Score | Response |
|---|---|
| 5 | Coos, babbles, smiles appropriately |
| 4 | Irritable cry, consolable |
| 3 | Cries to pain, inconsolable |
| 2 | Moans or grunts to pain |
| 1 | No response |
Standard (Verbal) Verbal Scale
| Score | Response |
|---|---|
| 5 | Oriented (knows name, place, time) |
| 4 | Confused conversation |
| 3 | Inappropriate words |
| 2 | Incomprehensible sounds |
| 1 | No response |
Clinical Interpretation
| GCS Score | Severity | Clinical Implications | Action Required |
|---|---|---|---|
| 15 | Normal | Fully conscious and alert | Routine observation; investigate cause of presentation |
| 13-14 | Mild | Minor impairment; may indicate concussion or early deterioration | Close observation; serial GCS monitoring; consider CT if head injury |
| 9-12 | Moderate | Significant impairment; at risk of deterioration |
|
| 3-8 | Severe / Coma | Cannot protect airway; high mortality risk |

Special Considerations in Children
Assessment Challenges
- Pre-verbal children: Cannot assess orientation - use paediatric verbal scale
- Developmental delay: Establish baseline function from carers
- Sedation: Document if sedated - GCS may not reflect true neurological status
- Intubated patients: Cannot assess verbal - document as "T" (e.g., E4VTM6)
- Eye swelling: Document as "C" if unable to assess (e.g., ECM6)
Trending GCS
Serial GCS measurements are more valuable than single readings:
- Drop of ≥2 points: Urgent medical review required
- Motor score deterioration: Particularly concerning - may indicate rising ICP
- Fluctuating GCS: May indicate seizures, metabolic disturbance, or intermittent raised ICP
- Failure to improve: May indicate ongoing pathology
Document time of each assessment and any interventions.
Frequently Asked Questions
The standard Glasgow Coma Scale was designed for adults and relies on verbal responses that pre-verbal children cannot provide. The Paediatric GCS modifies the verbal component to use age-appropriate responses such as cooing, babbling, and crying patterns. The motor and eye responses are similar but with age-appropriate expectations.
The Paediatric GCS is typically used for children under 5 years of age, particularly for pre-verbal infants and toddlers. Children aged 5 and above who can speak in sentences may be assessed using the standard adult GCS. The transition depends on the child's developmental level rather than strict age cutoffs.
A normal Paediatric GCS score is 15, the same as the adult scale. The minimum score is 3. A score of 8 or below indicates severe impairment and typically requires airway protection. Scores between 9-12 indicate moderate impairment, and 13-14 indicate mild impairment.
For infants and pre-verbal children, the verbal response is assessed differently: 5 = Coos and babbles normally, 4 = Irritable or crying but consolable, 3 = Cries to pain only, 2 = Moans or grunts, 1 = No response. This replaces the adult criteria of oriented speech.
A Paediatric GCS of 8 or below typically requires immediate senior review and consideration of airway management. Any drop of 2 or more points from baseline should prompt urgent medical review. A GCS of 14 or below in a previously well child warrants investigation and observation.
