CHALICE 儿童头外伤规则
用途适用： children presenting after head injury when a structured CT rule is appropriate.
分层Rule-positive → urgent CT pathway; rule-negative still needs advice and safeguarding.
局限不适用： when local NICE or PECARN pathways are mandatory and differ. · 易错点： underplaying non-accidental injury suspicion. · Age <1 year uses GCS <15 threshold.

- Abnormal drowsiness · 选项
- ≥ 3 post-traumatic vomits · 选项
- Suspicion of non-accidental injury · 选项
- Post-traumatic seizure (no prior epilepsy) · 选项

计算方法与公式
Any one positive history/exam/mechanism criterion → CT indicated; all negative → low risk.
Work through LOC/amnesia/drowsiness/vomiting/NAI/seizure/GCS/skull signs/focal deficit/infant bruise>5 cm/high-risk mechanism.
公式代入演示
下列数值取自本工具各输入项的示例值，用本页公式在服务端实际算出，供快速核对计算过程。仅演示代入方法，不构成临床建议，也不代表任何真实病例。
| Witnessed LOC > 5 minutes | 否 |
|---|---|
| Amnesia > 5 minutes | 否 |
| Abnormal drowsiness | 否 |
| ≥ 3 post-traumatic vomits | 否 |
| Suspicion of non-accidental injury | 否 |
| Post-traumatic seizure (no prior epilepsy) | 否 |
| GCS < 14 (< 15 if age < 1 year) | 否 |
| Suspicion of penetrating injury, depressed skull fracture or tense fontanelle | 否 |
| Signs of basal skull fracture | 否 |
| Focal neurologic deficit | 否 |
| Bruise / swelling / laceration > 5 cm (age < 1 year) | 否 / 不适用 |
| High-risk mechanism (RTC >40 mph, fall >3 m, or high-speed projectile) | 否 |
→CHALICERule-negative — low risk
- Positive items：None
- Age context：Derived for children presenting after head injury
| Witnessed LOC > 5 minutes | 是 |
|---|---|
| Amnesia > 5 minutes | 是 |
| Abnormal drowsiness | 是 |
| ≥ 3 post-traumatic vomits | 是 |
| Suspicion of non-accidental injury | 是 |
| Post-traumatic seizure (no prior epilepsy) | 是 |
| GCS < 14 (< 15 if age < 1 year) | 是 |
| Suspicion of penetrating injury, depressed skull fracture or tense fontanelle | 是 |
| Signs of basal skull fracture | 是 |
| Focal neurologic deficit | 是 |
| Bruise / swelling / laceration > 5 cm (age < 1 year) | 是 |
| High-risk mechanism (RTC >40 mph, fall >3 m, or high-speed projectile) | 是 |
→CHALICECT indicated (rule-positive)
- Positive items：12
- Age context：Derived for children presenting after head injury
结果判读与分层
Rule-positive → urgent CT pathway; rule-negative still needs advice and safeguarding.
指南要点（原创整理）
- Any-one-positive rule.
- Includes mechanism criteria.
- 下一步： PECARN / NICE as locally preferred; neurosurgery if deteriorating.

常见问题
- CHALICE 儿童头外伤规则的计算是否上传患者数据？在哪里计算？
- 计算在浏览器本地完成，输入与结果不上传服务器；结果仅供执业医师参考，须结合病史、检查与本机构方案判断，不构成诊断或处方依据。
- CHALICE 儿童头外伤规则怎么代入计算？能举个例子吗？
- 代入: Witnessed LOC > 5 minutes 否、Amnesia > 5 minutes 否、Abnormal drowsiness 否、≥ 3 post-traumatic vomits 否、Suspicion of non-accidental injury 否、Post-traumatic seizure (no prior epilepsy) 否、GCS < 14 (< 15 if age < 1 year) 否、Suspicion of penetrating injury, depressed skull fracture or tense fontanelle 否… → 结果: CHALICE Rule-negative — low risk（Positive items: None、Age context: Derived for children presenting after head injury） 代入: Witnessed LOC > 5 minutes 是、Amnesia > 5 minutes 是、Abnormal drowsiness 是、≥ 3 post-traumatic vomits 是、Suspicion of non-accidental injury 是、Post-traumatic seizure (no prior epilepsy) 是、GCS < 14 (< 15 if age < 1 year) 是、Suspicion of penetrating injury, depressed skull fracture or tense fontanelle 是… → 结果: CHALICE CT indicated (rule-positive)（Positive items: 12、Age context: Derived for children presenting after head injury）
