Cerebral Small Vessel Diseases, Cognitive Impairment, Dysphagia
Conditions
Brief summary
A prospective study was conducted on 84 CSVD patients with 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 SGB. 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.
Detailed description
In order to observe the effect of stellate ganglion block (SGB) on swallowing function, cognitive function and activities of daily living in patients with cerebral small vessel disease (CSVD), A prospective study was conducted on 84 CSVD patients with 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 SGB. 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.
Interventions
DRUGStellate ganglion block
Based on the invention above, the patients in the observation group were provided with SGB, 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 SGB. 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.
BEHAVIORALRehabilitation therapy
The study lasted 20d 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 (NGT) was provided.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Penetration-Aspiration Scale | day 1 and day 20 | On the day 1 and day 20, 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Modified Barthel Index | day 1 and day 20 | On the day 1 and day 20, 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. |
| Mini-Mental State Examination | day 1 and day 20 | On the day 1 and day 20, 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. |
| Swallowing duration | day 1 and day 20 | The time duration that the patient swallowed the contrast agent under Videofluoroscopic Swallowing Study the was recorded.Unit: seconds. |
