Clinical Trial Summary

The goal of this clinical trial is to test the efficacy of stellate ganglion block in Obstructive Sleep Apnea. The main question it aims to answer are: • Can stellate ganglion block improve Obstructive Sleep Apnea? Patients were randomly divided into two groups, all provided with routine therapy. Based on this, the experimental group was given stellate ganglion block. The video fluoroscopic swallowing study was done to test the swallowing function before and after the study.

Intervention

Behavioral:
• routine rehabilitation treatment
All participants were given routine rehabilitation treatment by professional rehabilitation therapists, including exercise therapy, guided education, psychological therapy, acupuncture and massage therapy

Procedure:
• Stellate ganglion block
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
The patients were provided with Stellate ganglion block , using 0.5ml of 2% Lidocaine hydrochloride (1ml: 0.5mg) and 500ug of Vitamin B12 (1ml: 0.5g). once a day, 10 days totally.

Procedure:
• Placebo injection
Normal saline is used. 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Epworth Sleepiness Scale	This scale measures daytime sleepiness. By scoring the level of sleepiness in different situations, it can help evaluate whether a patient has Obstructive Sleep Apnea or other sleep disorders.Scores range from 0-24. Higher scores indicate more severe daytime sleepiness.	day 1 and day 10
Secondary	Apnea-Hypopnea Index	Apnea-Hypopnea Index is a method to evaluate the severity of Obstructive Sleep Apnea. It calculates the number of apnea and hypopnea events per hour.	day 1 and day 10
