Investigation of Potential Mechanisms in Stellate Ganglion Block in Individuals With Cerebral Small Vessel Disease

Summary

This is a prospective study conducted on patients with Cerebral Small Vessel Disease, dysphagia and cognitive impairment. They were divided into the comparison group and observation group evenly. All the patients were provided with routine therapy, while the patients in the observation group were given Stellate Ganglion Block. The swallowing function, cognitive function and activities of daily living of the two groups of patients before and after treatment were evaluated by Penetration-Aspiration Scale, Mini-mental state examination and modified Barthel index.

Conditions

• Cerebral Small Vessel Diseases

Interventions

BEHAVIORAL

Rehabilitation therapy

The study lasted 10 days for each patient. During the treatment, All the participants were provided with the rehabilitation therapy, which included routine rehabilitation, cognitive training, swallowing function training and nutrition support. Particularly, due to dysphagia, the patients enrolled might face difficulty in eating. For patients who were able to finish intake via mouth by compensatory means, the consistency, type, and size of food bolus was arranged. For those who cannot acquire sufficient nutrition through oral intake, the nasogastric tube feeding was provided.

PROCEDURE

Stellate ganglion block

Based on the invention above, 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.
