Ultrasound-guided stellate ganglion blocks (SGBs) significantly improved chronic mild traumatic brain injury (TBI) symptoms over three months. The two-level cervical sympathetic chain blocks (2LCSBs) showed rapid, durable results with no observed sex-based differences.
Area of Science:
- Neurology
- Pain Management
- Regenerative Medicine
Background:
- Chronic mild traumatic brain injury (TBI) presents persistent neurobehavioral symptoms.
- Stellate ganglion blocks (SGBs) are being investigated for TBI symptom management.
- Previous research has not extensively evaluated bilateral, two-level SGBs for TBI.
Purpose of the Study:
- To assess the efficacy of ultrasound-guided, bilateral, two-level stellate ganglion blocks (2LCSBs) in improving chronic mild TBI symptoms over three months.
- To evaluate neurobehavioral symptom changes using the Neurobehavioral Symptom Inventory (NSI) scores.
- To investigate potential sex-based differences in treatment outcomes.
Main Methods:
- Retrospective chart review of 41 patients (28 males, 13 females) with chronic TBI.
- Patients received bilateral, two-level cervical sympathetic chain blocks (2LCSBs) on subsequent days.
- NSI scores were collected at baseline and at one week, one, two, and three months post-treatment.
Main Results:
- 85.36% of patients showed improvement in NSI scores, and 87.8% improved in NSI sub-scores.
- Average decrease in total NSI scores was 48.44% from baseline.
- No statistically significant differences in outcomes were observed between males and females.
Conclusions:
- Bilateral 2LCSBs demonstrate potential for rapid and sustained improvement in TBI symptoms for up to three months.
- The procedure appears effective regardless of patient sex.
- Further research is required to establish a causal relationship between 2LCSBs and TBI symptom improvement.
