“…At a 3‐month follow‐up after SGB, they observed at least a 40% reduction in pain. Besides, in a case of carcinoma buccal mucosa with chronic facial pain, PRF of SG resulted in up to 75% pain relief at the second‐week follow‐up and the sixth‐week follow‐up 44 . Atypical facial pain is also known as persistent idiopathic facial pain, and the pathogenesis may be related to autonomic dysfunction, psychological factors, central sensitization, demyelination, and axonal dysfunction 49 .…”

Stellate ganglion (SG) intervention is currently widely being studied in many kinds of chronic pain. As one of the convenient ways to treat the sympathetic nervous system, the indications for stellate ganglion intervention (SGI) include complex regional pain syndrome, postherpetic neuralgia, cancer pain of different origins, orofacial pain, and so forth. SGI refers to the reversible or irreversible blocking of the cervical sympathetic trunk, cervical sympathetic ganglion, and their innervation range through noninvasive or minimally invasive treatment. Current treatment options include stellate ganglion block (SGB), SG pulsed radiofrequency, continuous radiofrequency treatment, and noninvasive SGB. In particular, SGB continues to be one of the most studied methods in chronic pain management. However, a single SGB usually provides only short-term effects; repeated SGB may result in complications such as hoarseness, light-headedness, and vessel or nerve injury. Meanwhile, the mechanism of SGI is still unclear. This review discusses the research progress of SGI methods, effectiveness, complications, and possible mechanisms in the management of chronic pain.chronic pain, pulse radiofrequency, stellate ganglion, stellate ganglion block | INTRODUCTIONChronic pain is defined as pain that persists or recurs for more than 3 months, usually accompanied by negative emotions including anxiety and/or depression. 1 Chronic pain severely affects not only physical and mental health but also places a huge economic burden on the family and society. The incidence of chronic pain is reported to be over 30% in China. 2 Current conventional methods for the treatment of chronic pain include drug therapy, minimally invasive therapy, psychotherapy, and physical therapy. 3 However, research has found that sympathetic nerves are involved in the maintenance of many kinds of chronic pain. 4 Therefore, inhibition of sympathetic hyperexcitability may improve the therapeutic effect, which may be related to the involvement of sympathetic nerves in regulating glial inflammation. 5 Among them, intervention of stellate ganglion (SG) is effective for pain in the head, face, neck, upper limbs, or upper chest. In this review, we summarize the clinical evidence available for the effectiveness of stellate ganglion intervention (SGI), and demonstrate clinical applications of SGI.

“…Amputations result in both nociceptive and neuropathic symptoms with a high risk of developing chronic pain. As a result, the perioperative period has been an obvious target for varied interventions including physical, behavioural and pharmacological interventions (beta-blockers, antidepressants, anticonvulsants, selective serotonin reuptake inhibitors, ketamine), and percutaneous peripheral nerve stimulation, peripheral nerve blocks (popliteal, sciatic nerve blocks) and radiofrequency ablation to prevent the occurrence of chronic pain but have provided variable results,[ 13 14 15 16 17 18 19 20 ] aiming to reduce or prevent the phenomenon. [ 21 ] Both central and peripheral nerve blocks have been used; however, the short- and long-term outcomes remain debatable.…”

Background and Aims: Many pain syndromes such as chronic phantom limb pain (PLP) and stump pain (SP), involving nociceptive and neuropathic pain, develop after amputation. Recent literature suggests that the use of regional blocks reduces repeated stimulation of transected nerve roots and thus prevents central sensitisation. This randomised, double-blind study was conducted to evaluate the effect of pre-emptive ultrasound-guided single-shot lateral sciatic nerve block on the occurrence of chronic pain at six months after traumatic below-knee amputation. Methods: Thirty patients undergoing traumatic lower limb amputation under general anaesthesia were randomised into two groups: Group B received sciatic nerve block pre-emptively using ultrasound with 20 ml of 0.75% ropivacaine, whereas group C received 20 ml of normal saline. Follow-up of patients was done till six months post-amputation. The primary objective was to assess the occurrence of chronic pain at six months. Pain at 15 days and one month after surgery, post-operative morphine consumption and post-operative nausea and vomiting (PONV) were the secondary outcomes assessed. Results: The occurrence of PLP at six months was comparable in the two groups, group B (46.7%) and C (66.7%). None of the patients developed SP at six months. Median intensities of phantom pain were 1.0 (range, 1–2.0) versus 1.0 (range, 1–2.0) ( P = 0.36), and median intensities of SP 2 (range, 2–3.0) versus 3 (range, 2–3.0) ( P = 0.39) at 1 month. Conclusion: Pre-emptive sciatic nerve block did not decrease the occurrence or severity of chronic pain after traumatic below-knee amputation.
