Insights
Serious injuries from blunt head trauma are rare in children, though injury patterns and mechanisms vary by age. Teenagers showed higher rates of significant injury and intervention, with temporal and frontal regions most affected.
Area of Science:
- Pediatric Emergency Medicine
- Neurotrauma
- Radiology
Background:
- Pediatric head trauma is a common emergency department presentation.
- Limited data exists on specific injury patterns in children with head trauma.
Purpose of the Study:
- To evaluate head injury patterns in pediatric patients with blunt head trauma.
- To determine the prevalence of these injuries across different age groups.
Main Methods:
- Secondary analysis of the NEXUS II Head CT validation study.
- Included consecutive pediatric patients with blunt head trauma (2006-2015).
- Analyzed injury frequencies and severity by age group using radiologist reports.
Main Results:
- 12.6% of 1018 pediatric patients had injuries on CT scans.
- Subarachnoid hemorrhage and subdural hematoma were most common.
- Teenagers had the highest rates of significant injury (50%) and intervention (30%).
- Falls were the most common injury mechanism (24.7%).
Conclusions:
- Serious injuries requiring intervention are uncommon in pediatric blunt head trauma.
- Injury mechanisms, types, and intervention rates differ across pediatric age groups.
Objectives:
Pediatric head trauma is a frequent reason for presentation to the emergency department. Despite this, there are few reports on specific characteristics and injury patterns in head injured children. The goal of this study was to evaluate head injury patterns in children with blunt head injury and their prevalence by age group.
Methods:
This is a planned secondary analysis of the NEXUS II Head CT validation study. Consecutive patients with blunt head trauma were enrolled between 2006 and 2015. Demographics and criteria from 2 clinical decision instruments (NEXUS and Canadian Head CT rules) were gathered at the time of enrollment. We abstracted and cataloged injuries for pediatric patients based on radiologist report. Frequencies of injuries and severity were analyzed by developmental age group.
Results:
A total of 1018 pediatric patients were enrolled, 128 (12.6%) of whom had an injury on computed tomography scan. Median age was 11.9 (Interquartile range 4.5-15.5) for all patients and 12 (4.8-15.5) for injured patients. Of injured patients, 49 (38.3%) had a significant injury, and 27 (21.1%) received an intervention. Teenagers had the highest rate of significant injury (50%) and intervention (30%). Injuries were most frequently noted in the temporal (46.1%), frontal (45.3%), and parietal (45.3%) regions. Subarachnoid hemorrhage (29.7%) and subdural hematoma (28.9%) were the most common injuries observed.Intraparenchymal hemorrhage and cerebral edema were more prevalent in older age groups. The most common injury mechanism overall was fall from height (24.7%). Motor vehicle accidents and nonmotorized wheeled vehicle accidents were more common in older patients.
Conclusions:
Serious injuries requiring intervention were rarely encountered in pediatric patients experiencing blunt head trauma. Mechanisms of injury, type of injury, and rates of intervention varied between developmental age groups.
