Stellate Ganglion Block (SGB): A Solution for Chronic Pain
Stellate ganglion block (SGB) is a specialized procedure used to relieve
chronic pain, particularly that mediated by the sympathetic nervous system. This technique
involves injecting a local anesthetic around the stellate ganglion, a group of
nerves located in the neck, to reduce pain signals and improve quality of life.
Clinical applications of BGS
- Pain: Pain is regional, not related to an identifiable nerve lesion (CRPS type 1). It may be burning, stabbing or accompanied by abnormal sensations (allodynia, hyperalgesia).
- Skin and vascular alterations:
◦ Changes in skin color or temperature.
◦ Swelling or edema in the affected area.
◦ Dryness or excessive sweating. - Motor and functional disorders: joint stiffness, muscle weakness and reduced range of motion.
Characteristics and symptoms
1. Chronic post-surgical pain
- Post-mastectomy: BGS, especially with specific injections such as alcohol, can significantly reduce pain and painkiller consumption.
- Thoracic surgery: effectively relieves perioperative visceral pain and reduces post-operative opioid use.
- Effective for chronic pain, with results sometimes prolonged by radiofrequency thermocoagulation.
- Indicated for chest pain associated with pathologies such as primary pulmonary hypertension.
- Post-traumatic stress disorder: Improves symptoms linked to anxiety and stress.
- Post-menopausal hot flushes and lymphatic edema: relief observed in some cases.
BGS benefits
- Rapid relief: Significant pain reduction immediately after injection.
- Medication reduction: Reduced opioid dependence.
- Wide range of applications: Used for a wide range of pain and non-pain disorders.
Stellate ganglion block is a precise, targeted procedure that temporarily interrupts nerve signals to relieve severe pain and restore balance to the nervous system.
Challenges and limitations :
- Long-term efficacy: Relief is often temporary, requiring repeated blocks or additional procedures such as thermocoagulation.
- Possible complications:
- Transient side effects: hoarseness, dizziness, facial flushing.
- Rare risks: vascular or nerve damage.
Conclusion
Stellate ganglion block is a promising option for the management of chronic pain and certain non-painful conditions. If you suffer from chronic pain or sympathetic nervous system disorders, talk to a specialist to determine if this method may be right for you
