The Possible Preventive Role of Pregabalin in Postmastectomy Pain Syndrome: A Double-Blinded Randomized Controlled Trial.

Context: Chronic postmastectomy pain syndrome (PMPS) has a considerable negative impact on the quality of life of breast cancer patients.

Objective: The objective of this study was to assess the possible preventive role of perioperative pregabalin in PMPS.

Methods: This randomized controlled study included 200 patients with breast cancer scheduled for elective breast cancer surgery.

Fluoroscopic stellate ganglion block for postmastectomy pain: a comparison of the classic anterior approach and the oblique approach.

Objective: Stellate ganglion block is usually performed with the classic anterior paratracheal approach. The anatomy of the stellate ganglion being in close proximity to various critical structures renders a number of complications, which are potentially associated with its blockade. The aim of this study was to assess the analgesic efficacy and safety of a new approach of the stellate ganglion block using an oblique fluoroscopic view.
