Abstract

Objective: To evaluate the effect of stellate ganglion block and gabapentin on post mastectomy
pain.

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
