Insights
A Glasgow Coma Scale score of 5 is the critical predictor for outcomes in pediatric traumatic brain injuries. This finding aids in assessing injury severity and guiding treatment for children with TBI.
Area of Science:
- Pediatric Neurology
- Trauma Surgery
- Neurocritical Care
Background:
- Traumatic brain injuries (TBI) are a significant cause of morbidity and mortality in children.
- Accurate prognostication is crucial for effective management of pediatric TBI.
- The Glasgow Coma Scale (GCS) is widely used, but its predictive value in children requires further definition.
Purpose of the Study:
- To determine the predictive critical value of the Glasgow Coma Scale (GCS) for outcomes in pediatric traumatic brain injuries (TBI).
- To identify specific neuroimaging findings associated with severe injury and poor outcomes in this population.
Main Methods:
- A cohort of 309 children (aged 2-10 years) with TBI was assessed.
- Data collected included GCS scores, clinical data, brain computed tomography (CT), and Glasgow Outcome Scale (GOS) assessments.
- Receiver operating characteristic (ROC) curve analysis was used to identify the critical GCS score.
Main Results:
- A GCS critical point of 5 demonstrated the strongest correlation with outcomes in pediatric TBI.
- Subarachnoid hemorrhage, brain swelling, edema, subdural/intracerebral hemorrhage, and basal ganglion lesions were linked to severe injury and poor outcomes (P < 0.05).
- Cortical lesions did not significantly impact injury severity or outcome, while chest trauma showed a tendency towards poor outcomes (P < 0.05).
Conclusions:
- The Glasgow Coma Scale score is the most effective predictor of outcome in pediatric TBI.
- A predictive critical GCS score of 5 is recommended for pediatric TBI.
- CT findings are also important for determining injury severity and predicting outcomes in pediatric TBI.
Abstract:
The aim of this study is to determine the predictive critical value of the Glasgow Coma Scale for use as a determinant of outcome for children with traumatic brain injuries. A total of 309 children, aged 2-10 years, were enrolled in this study. Each subject underwent the following assessments: Glasgow Coma Scale; clinical data; brain computed tomography; and Glasgow Outcome Scale assessments. The receiver operating characteristic curve indicated that a critical point of the Glasgow Coma Scale set at 5 was most strongly correlated with outcome of pediatric traumatic brain injury. Subarachnoid hemorrhage with brain swelling and edema, subdural, intracerebral hemorrhage, and basal ganglion lesions were associated with severe injury and poor outcome (P < 0.05). However, cortical lesions did not affect injury severity and outcome. In injuries associated with traumatic brain injuries, only chest trauma had a tendency to be associated with poor outcome (P < 0.05). Of the factors analyzed, the score of the Glasgow Coma Scale was the most effective predictor for outcome in pediatric traumatic brain injury. Furthermore, the predictive critical score of the Glasgow Coma Scale should be set at 5 for pediatric traumatic brain injury. The computed tomographic findings also were important in determining injury severity and predicting outcome.
