Overview
Brief Summary
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.
Detailed 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). 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.

Arms & Interventions
The observation group
Patients enrolled were firstly numbered for privacy with software and divided into the observation group (n=33) and the control group (n=33) with a random number table. Additionally, the staffs involved in assessment would not participate in the intervention of the study. The treatment lasted 20 days.
Intervention: comprehensive rehabilitation

Outcomes
Primary Outcomes
Video fluoroscopic swallowing study
Time Frame: day 1 and day 20
The patient was required to take a sitting position with the head naturally upright. Under the guidance of the examiner, the patient first swallowed 5ml of iohexol solution (50ml:17.5g in iodine terms). If the patient exhibited aspiration, the test would stop. If not, the patient was instructed to swallow 10ml of iohexol solution mixed with breadcrumbs, and the patient's swallowing condition was observed with immediate measures ready to take for safety. Specially, the esophageal phase was not included in the study, because it was commonly regarded as an independent phase. The swallowing were divided into 3 phases in this assessment: Oral phase, Pharyngeal phase, and Aspiration, with maximum 3,3,4 points were given to each phase. The total score was calculated as the final result. The final score was positively correlated with the swallowing function.
Secondary Outcomes
- Rosenbek penetration-aspiration scale(day 1 and day 20)
- Kubota water swallowing test(day 1 and day 20)
