- Study explores effects of ultrasound-guided stellate ganglion block (SGB) on poststroke bulbar palsy.
- Randomized double-blind placebo-controlled trial with 124 participants in China from March 2024 to July 2025.
- SGB group received lidocaine hydrochloride; placebo group received normal saline.
- Primary outcome: clinical severity of dysphagia.
- Secondary outcomes: airway protection, hyoid bone movement, secretions, pharyngeal residue, anxiety, and vertebral artery blood flow.
- Significant improvements in dysphagia severity, hyoid bone movement, airway protection, and anxiety observed in SGB group.
- Temporary increase in vertebral artery blood flow post-SGB, but functional improvements were long-term.
- SGB is safe and effective for improving swallowing function and reducing anxiety in poststroke bulbar palsy patients.
