Condition(s) targeted: Postoperative Pain

We hypothesize that pregabalin will decrease postoperative pain, as measured by the
surrogate markers postoperative pain rating scores and postoperative opioid consumption
while improving the quality of recovery following breast cancer surgery compared to placebo.
The primary outcome will be postoperative pain, measured by a NRS and the quality of
recovery score (QoR) in the first 24h postoperative period. Do women undergoing breast
cancer surgery with general anesthesia and receiving pregabalin prior to their surgery and
12 hours later have lower NRS and a greater QoR score in the first 24 hours after their
surgery than those women who received placebo?
Official title: A Randomized, Placebo Controlled Trial of Pregabalin for Postoperative Pain in Women Undergoing Breast Cancer Surgery
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: The primary outcome will be postoperative pain, measured by a NRS and the quality of recovery score (QoR) in the first 24h postoperative period.
Secondary outcome: NRS / QoR - 48 hour Opioid Consumption Side effects - nausea, sedation
Minimum age: N/A.
Maximum age: 65 Years.
