About

This was a multicenter randomized controlled study. 66 post-stroke patients with pharyngeal dysphagia were randomly allocated to the observation group (n=33) or the control group (n=33). Both groups were provided with comprehensive rehabilitation including routine rehabilitation and swallowing function training. Besides, the observation group additionally underwent the stellate ganglion block (SGB). At admission and after 20-day treatment, Kubota water swallowing test, video fluoroscopic swallowing study (VFSS), and Rosenbek penetration-aspiration scale (PAS) were used to assess swallowing function.

Full description

Dysphagia is a frequent and potentially serious complication of stroke. However, there is no effective measure for the treatment of pharyngeal dysphagia in stroke patients. This study aims to explore the efficacy of stellate ganglion block in post-stroke pharyngeal dysphagic patients who received comprehensive rehabilitation. This was a multicenter randomized controlled study. 66 post-stroke patients with pharyngeal dysphagia were randomly allocated to the observation group (n=33) or the control group (n=33).
