Evaluation of T2, T3 Sympathectomy for Postmastectomy Pain Syndrome by Pulse Oximeter

Evaluation of T2, T3 Sympathectomy for Postmastectomy Pain Syndrome by Thermal Radiofrequency Versus Chemical Neurolysis Using Perfusion Index Derived Pulse Oximeter

The aim of the study is to compare the efficacy of T2, T3 sympathetic block using thermal radiofrequency versus chemical neurolysis in postmastectomy pain syndrome using perfusion index derived from pulse oximetry.

Postmastectomy pain is a chronic pain condition with neuropathic nature. Several drugs and methods are used for its management. This study was designed to compare the efficacy of both thermal radiofrequency and chemical neurolysis in management of postmastectomy pain through using perfusion index derived from pulse oximetry.
