What this trial studies

This study evaluates the effectiveness of combining ultrasound-guided radiofrequency stellate ganglion block (SGB) and thoracic paravertebral block (TPVB) in treating post-mastectomy pain syndrome (PMPS). It aims to compare this combined approach to using either SGB or TPVB alone. The study focuses on female patients who have undergone modified radical mastectomy and are experiencing moderate to severe pain that has not responded to strong opioids and adjuvant therapies. The goal is to provide a more effective pain management strategy for those suffering from complex regional pain syndrome following breast cancer surgery.

Who should consider this trial

Good fit: Ideal candidates are female patients who have undergone modified radical mastectomy and are experiencing moderate to severe refractory pain for more than six months.

Not a fit: Patients with severe respiratory or cardiac disorders, advanced liver or kidney disease, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management for women suffering from post-mastectomy pain syndrome.

How similar studies have performed: While the combination of these specific interventions is novel, similar approaches in pain management have shown promise in other studies.
