Metodología · ejemplo, guías y notas completas
4 high + 3 medium (+ CATCH2 vomit≥4).
Cuándo usarla
Cuándo usar: children with minor head injury (GCS 13–15) plus LOC, amnesia, disorientation, vomiting, or irritability — as in derivation.
Cómo funciona
High (any → CT): GCS <15 at 2 h; suspected open/depressed skull fx; worsening headache; irritability. Medium (CT vs observe): basal skull-fx signs; large boggy scalp hematoma; dangerous mechanism; CATCH2 adds ≥4 vomits.
Puntos clave
- 4 high + 3 medium (+ CATCH2 vomit≥4).
- Any high → CT.
- Siguiente: PECARN / CHALICE / neurosurgery.

Nota de la herramienta
Para profesionales sanitarios; no sustituye el juicio clínico.
Cálculo de ejemplo
Los valores siguientes proceden de los ejemplos definidos en la propia herramienta y se calculan en el servidor con la fórmula de esta página, para poder verificar la operación rápidamente. Solo ilustra cómo sustituir los valores: no es consejo clínico ni un caso real.
| High: GCS < 15 at 2 h after injury | No (0) |
|---|---|
| High: Suspected open or depressed skull fracture | No (0) |
| High: History of worsening headache | No (0) |
| High: Irritability on examination | No (0) |
| Medium: Any sign of basal skull fracture | No (0) |
| Medium: Large boggy scalp hematoma | No (0) |
| Medium: Dangerous mechanism (MVC; fall ≥3 ft / 5 stairs; fall from bicycle without helmet) | No (0) |
| CATCH2 add-on: ≥ 4 discrete vomiting episodes | No (0) |
→CATCHRule-negative — low risk
- High-risk hits：0
- Medium-risk hits：0
| High: GCS < 15 at 2 h after injury | Yes — high risk |
|---|---|
| High: Suspected open or depressed skull fracture | Yes — high risk |

Preguntas frecuentes
Preguntas frecuentes
- ¿Regla CATCH (TC craneal pediátrica) sube datos del paciente? ¿Dónde se calcula?
- El cálculo se realiza localmente en el navegador; no se suben datos. Solo para profesionales sanitarios; interprete con historia, pruebas y protocolos locales — no es diagnóstico ni prescripción.
- ¿Cómo se calcula Regla CATCH (TC craneal pediátrica) en la práctica? ¿Puede mostrar un ejemplo resuelto?
- Datos: High: GCS < 15 at 2 h after injury No (0), High: Suspected open or depressed skull fracture No (0), High: History of worsening headache No (0), High: Irritability on examination No (0), Medium: Any sign of basal skull fracture No (0), Medium: Large boggy scalp hematoma No (0), Medium: Dangerous mechanism (MVC; fall ≥3 ft / 5 stairs; fall from bicycle without helmet) No (0), CATCH2 add-on: ≥ 4 discrete vomiting episodes No (0) → Resultado: CATCH Rule-negative — low risk（High-risk hits: 0, Medium-risk hits: 0） Datos: High: GCS < 15 at 2 h after injury Yes — high risk, High: Suspected open or depressed skull fracture Yes — high risk, High: History of worsening headache Yes — high risk, High: Irritability on examination Yes — high risk, Medium: Any sign of basal skull fracture Yes — medium risk, Medium: Large boggy scalp hematoma Yes — medium risk, Medium: Dangerous mechanism (MVC; fall ≥3 ft / 5 stairs; fall from bicycle without helmet) Yes — medium risk, CATCH2 add-on: ≥ 4 discrete vomiting episodes Yes — CATCH2 medium → Resultado: CATCH High risk — CT recommended（High-risk hits: 4, Medium-risk hits: 4, CATCH2 vomit≥4: Yes）
