Clinical trial

A Double-blind Randomized Controlled Study to Explore Effectiveness of Stellate Ganglion Block in Managing Dysphagia in Patients With Medullary Infarction

Name

SGB-BP

Description

This is a randomized controlled study, including dysphagic patients with bulbar palsy after ischemic stroke who were received in the department of rehabilitation medicine. All patients are randomly allocated to the observation group or the control group. Both groups are provided with comprehensive rehabilitation. Besides, the observation group additionally undergoes the stellate ganglion block. At admission and after 10-day treatment, video fluoroscopic swallowing study, and penetration-aspiration scale, Functional Oral Intake Scale, Flexible laryngoscope are used to assess swallowing function.

Treatment

Comprehensive rehabilitation

All the participants are provided with the comprehensive rehabilitation (routine rehabilitation and swallowing function training). The routine rehabilitation included intervention for risk factors (blood pressure, blood lipids, blood glucose, smoking and alcohol restriction, exercise, etc.). Regrading swallowing function training, both groups are given swallowing function training, including 1) exercises of closure of the vocal folds, pharyngeal, and laryngeal muscles exercises, and respiratory muscle strength training, for 15 min each time and twice per day. 2) isotonic／isometric swallowing exercises, supraglottic swallowing exercises, for 20 min each time and twice per day. 3) effortful swallowing exercises, and cough reflex training, for 10 min each time and twice per day.

Injection

the patients in the observation group were provided with Injection. The percutaneous approach via the paratracheal route was used for Stellate ganglion block. The operator stood on the side of the block, instructed the patient to lie supine with a thin pillow placed below the shoulders, and tilted the head 45° towards the blocked side, fully exposing the neck. Then, routine disinfection of the neck skin was performed. The puncture site was located 2.5 cm above the sternoclavicular joint and 1.5 cm lateral to the midline of the neck.

Lidocaine Hydrochloride

the patients in the observation group were provided with Stellate ganglion block, using 1.5ml of 2% Lidocaine hydrochloride (1ml: 0.5mg) and 500ug of Vitamin B12 (1ml: 0.5g). The percutaneous approach via the paratracheal route was used for Stellate ganglion block. The operator stood on the side of the block, instructed the patient to lie supine with a thin pillow placed below the shoulders, and tilted the head 45° towards the blocked side, fully exposing the neck. Then, routine disinfection of the neck skin was performed. The puncture site was located 2.5 cm above the sternoclavicular joint and 1.5 cm lateral to the midline of the neck.
