Stellate Ganglion Block in Patients With Cerebral Small Vessel Disease

A Randomized Controlled Trial For Exploration of Stellate Ganglion Block in Patients With Cerebral Small Vessel Disease

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Rehabilitation therapy+Stellate ganglion block; The study lasted 10d 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. 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).	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.; Drug: Lidocaine Hydrochloride; 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.; Behavioral: Rehabilitation therapy; 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.
Placebo Comparator: Rehabilitation therapy+placebo; The study lasted 10d 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.	Behavioral: Rehabilitation therapy; During the treatment, All the participants were provided with the rehabilitation therapy, which included routine rehabilitation, cognitive training, swallowing function training and nutrition support.

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.; Behavioral: placebo injection; 1 milliliter of normal saline will be used for 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Penetration-Aspiration Scale	Penetration-Aspiration Scale was used to assess dysphagia under Videofluoroscopic Swallowing Study, primarily evaluating the extent to which fluid food entered the airway and caused penetration or aspiration during the swallowing process. As the level increased, the severity of dysphagia also increased.	day 1 and day 10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Functional Oral Intake Scale	During Dysphagia-Functional Oral Intake Scale assessment, evaluators engage in communication with the patient, conduct observations, and make records to assess the patient's oral intake ability. The Functional Oral Intake Scale assessment form includes seven levels of scoring, ranging from level 1 to level 7, indicating a progressive improvement in the patient's oral intake ability. In general, the result below level 6 indicates unsafe for oral intake while level 6 and above indicates that eating via mouth can be safely conducted.	day 1 and day 10
Mini-Mental State Examination	the cognitive function of patients was assessed using the Mini-Mental State Examination (MMSE). The MMSE evaluated five aspects, including orientation, memory, attention and calculation abilities, recall ability, and language skills, with a total score of 30 points. A MMSE score of less than 27 indicated cognitive impairment, with scores ≤9 indicating severe impairment, 10-20 indicating moderate impairment, and 21-26 indicating mild impairment.	day 1 and day 10
Modified Barthel Index	the activities of daily living of patients were assessed using the modified Barthel Index . The scale included 10 items such as feeding, bathing, walking, dressing. Each item was rated on a 4-point scale based on the level of assistance required, with a total score of 100 points. There was a positive correlation between activities of daily living and the final score.	day 1 and day 10
