Impact of Glossopharyngeal Nerve Block on Swallowing Difficulties Caused by Gastroesophageal Reflux Disease

Summary

The goal of this clinical trial is to explore Clinical Effect of Glossopharyngeal Nerve Block on Pharyngeal Dysphagia Induced by Gastroesophageal Reflux Disease. The main question it aims to answer is:

• Can Glossopharyngeal Nerve Block improve dysphagia caused by gastroesophageal reflux symptoms on the basis of rehabilitation training? Participants will be randomly allocated into the control group or the experimental group, all under rehabilitation treatment, the experimental group will be given Glossopharyngeal Nerve Block once a day additionally. The study lasts 20 days for each participant. Researchers will compare the Rosenbek penetration-aspiration scale, Gastroesophageal Reflux Disease Questionnaire, Pressure pain threshold, to see if the Glossopharyngeal Nerve Block can help improve the symptom.

Conditions

• Dysphagia

Interventions

BEHAVIORAL

Rehabilitation therapy

Rehabilitation therapy includes Diet management: Avoiding consumption of irritant foods and beverages, such as spicy foods, caffeine, alcohol, and acidic foods. Controlling portion sizes and meal timing, and adopting smaller, more frequent meals. Lifestyle adjustments: Avoiding lying down or bending immediately after meals, maintaining a sitting or upright position for at least 2 hours. Adjusting sleeping positions by elevating the head of the bed to reduce nighttime acid reflux. Avoiding excessive exertion and managing stress levels. Rehabilitation training: Strengthening the control of esophageal and gastric muscles through rehabilitation exercises to improve the function of the gastroesophageal sphincter and prevent gastric fluid reflux.

PROCEDURE

Glossopharyngeal Nerve Block

The patient lies supine without a pillow, turns the head to the contralateral side of the block, and at the midpoint of the line connecting the angle of the mandible with the mastoid process (the styloid process), the skin is disinfected, and a 22-gauge, 3.8 cm puncture needle is loaded onto a 5 mL syringe. The puncture needle is inserted perpendicularly to the skin surface at the styloid process, and advanced through the skin and subcutaneous tissue until it contacts the bone of the styloid process. The puncture needle is then retracted and advanced anteriorly beyond the styloid process by 0.5-1.0 cm. When no blood or cerebrospinal fluid is aspirated, the blocking drug can be injected \[20 g/L lidocaine injection\].

DRUG

Lidocaine Hydrochloride

When no blood or cerebrospinal fluid is aspirated, the blocking drug can be injected \[20 g/L lidocaine injection\]. once a day. 1 ml per time.

BEHAVIORAL

placebo injection

The patient lies supine without a pillow, turns the head to the contralateral side of the block, and at the midpoint of the line connecting the angle of the mandible with the mastoid process (the styloid process), the skin is disinfected, and a 22-gauge, 3.8 cm puncture needle is loaded onto a 5 mL syringe. 1 milliliter of normal saline will be used for injection.
