Effect of Stellate Ganglion Block on Drooling in Parkinson's Syndrome

Effect of Stellate Ganglion Block on Drooling in Parkinson's Syndrome: A Randomized Controlled Study

This is a randomized controlled study, including dysphagic patients with Parkinson's syndrome 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, Functional Oral Intake Scale, Drooling amount, depression are assessed.

Study Overview

• Status: Not yet recruiting
• Conditions: Parkinson's Syndrome
• Intervention / Treatment: Procedure: Stellate ganglion block; Drug: Lidocaine hydrochloride; Procedure: Placebo injection; Behavioral: Comprehensive rehabilitation

Detailed Description

Palliation of dysphagia in patients with Parkinson's syndrome continues to be a challenge.

This is a randomized controlled study, including dysphagic patients with Parkinson's syndrome 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, Functional Oral Intake Scale, Drooling amount, depression are assessed.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Comprehensive rehabilitation+Stellate ganglion block; Patients enrolled are firstly numbered for privacy with software and divided into the observation group and the control group with. Additionally, the staffs involved in assessment would not participate in the intervention of the study. The treatment lasts 10 days.	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).

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: Comprehensive rehabilitation; 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.
Placebo Comparator: Comparator: Comprehensive rehabilitation+placebo; Patients enrolled are firstly numbered for privacy with software and divided into the observation group and the control group with. Additionally, the staffs involved in assessment would not participate in the intervention of the study. The treatment lasts 10 days.	Procedure: 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
Drooling amount	All participants' saliva was collected within 5 minutes into a cup, followed by the comparison of saliva quantity, composition 1 hour before noon, the amount will be recorded.	day 1 and day 10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Modified Barthel Index	the activities of daily living of patients will be assessed using the modified Barthel Index . The scale includes 10 items such as feeding, bathing, walking, dressing. Each item is rated on a 4-point scale based on the level of assistance required, with a total score of 100 points. There is a positive correlation between activities of daily living and the final score.	day 1 and day 10
Patient Health Questionnaire-9	Patient Health Questionnaire-9 (PHQ-9) is a commonly used depression screening tool consisting of 9 items, designed to assess the severity of individual depressive symptoms. Each item is rated from 0 (not at all) to 3 (nearly every day) based on how the individual has been feeling over the past two weeks. The total score ranges from 0 to 27, and the severity of depressive symptoms is assessed as follows: 0-4: Minimal depression 5-9: Mild depression 10-14: Moderate depression 15-19: Moderately severe depression 20 and above: Severe depression When assessing the severity of depressive symptoms, a higher total score indicates more severe symptoms, while a lower total score indicates milder symptoms.	day 1 and day 10
