Insights
Clinical features like low Glasgow Coma Scale scores and focal deficits predict abnormal head CT scans in children. This can help limit CT use to patients with specific symptoms, improving care and reducing costs.
Area of Science:
- Pediatric Emergency Medicine
- Neuroradiology
- Clinical Neurology
Background:
- Head injuries are common in children.
- Computed tomography (CT) scans are frequently used for diagnosis.
- Identifying which children require CT scans is crucial for efficient healthcare.
Purpose of the Study:
- To determine if clinical features of head injury in children correlate with abnormal CT scan findings.
- To identify specific clinical indicators that predict the need for CT scans in pediatric head trauma.
Main Methods:
- Retrospective study of 311 children (14 years or younger) admitted with acute head injury.
- Analysis of clinical features and correlation with CT scan results.
Main Results:
- Glasgow Coma Scale (GCS) score of 12 or lower and focal neurological deficits were significant predictors of abnormal CT scans.
- 95% of abnormal CT scans and 100% of intracranial injuries were identified using specific clinical findings.
- Other indicators included loss of consciousness, ataxia, amnesia, drowsiness, headache, seizure, or vomiting.
Conclusions:
- CT scans can be reserved for children with persistent specific symptoms or focal neurological signs.
- Implementing clinical guidelines for pediatric head injuries can significantly impact practice and reduce healthcare expenses.
Objective:
To evaluate whether clinical features associated with head injury in children can be correlated with an abnormal computed tomography (CT) scan.
Methodology:
Three hundred and eleven children aged 14 years or younger admitted with a diagnosis of acute head injury were studied retrospectively.
Results:
A Glasgow Coma Scale (GCS) score of 12 or lower and the presence of focal neurological deficits were significant predictors of an abnormal CT scan. Ninety-five per cent of those with abnormal CT scans and 100% of those with intracranial injury could be identified by the presence of one or more of the nine clinical findings, particularly by a GCS score of 12 or lower, and the presence of focal neurological deficits. Identification was also possible to a lesser degree by loss of consciousness, ataxia, amnesia, drowsiness, headache, seizure or vomiting.
Conclusion:
Use of CT scans can be limited to children with ongoing specific symptoms and/or focal neurological signs. The implementation of guidelines in the management of head injuries in children could have a substantial effect on clinical practice and health-care costs.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
