Comparing the effect of stellate ganglion block and gabapentin on the post mastectomy pain syndrome

Abstract

Objective: To evaluate the effect of stellate ganglion block and gabapentin on post mastectomy pain. Methods: Sixty patients referred from departments of oncology and surgery to pain clinic were allocated to two groups. In group A, stellate ganglion block was performed with 8ml bupivacaine 0.25%. In group B, patients were treated with gabapentin 900mg per day in three divided doses. Drug dose was increased if necessary until eight weeks. Pain score and quality of life were determined. Data were collected before treatment, 48 hours and every 15 days after treatment until three months. Results: Pain scores at 48 hours after treating were higher in group B than group A and lower at one week, one month and three months after treatment which were statically significant. (P<0.001, 0.024, 0.047 and <0.001 respectively) Conclusions: Gabapentin was found to be superior treatment for chronic pain following breast surgery.
