Summary
Mild traumatic brain injury patients with coagulopathy, anticoagulant use, lower Glasgow Coma Scale (GCS), or advanced age face higher risks. Specific CT findings like midline shift also predict clinical deterioration.
Area of Science:
- Neuroscience
- Emergency Medicine
- Radiology
Background:
- Mild traumatic brain injury (mTBI) is common, but predicting clinical deterioration remains challenging.
- Identifying risk factors is crucial for appropriate patient management and resource allocation.
Purpose of the Study:
- To identify predictors of clinical deterioration in patients diagnosed with mild traumatic brain injury.
- To evaluate the role of initial computed tomography (CT) findings and patient characteristics in predicting adverse outcomes.
Main Methods:
- A prospective cross-sectional study involving 203 patients with mTBI.
- All patients underwent brain CT scans and were monitored for 6-48 hours.
- Statistical analysis identified factors associated with neurological decline.
Main Results:
- Clinical deterioration occurred in 1.5% of patients.
- Risk factors for deterioration included coagulopathy, anticoagulant use, Glasgow Coma Scale (GCS) of 13-14, and increased age.
- CT findings associated with deterioration were midline shift, cerebral contusions, and diffuse cerebral edema. Subdural hematoma (SDH) was the only hematoma type predicting worse outcomes.
Conclusions:
- While clinical deterioration is infrequent in mTBI, specific patient and imaging factors increase this risk.
- Early identification of patients with coagulopathy, on anticoagulants, with lower GCS, advanced age, or specific CT findings (midline shift, contusions, edema, SDH) is essential for vigilant monitoring and management.
