Impact of Pregabalin in Chronic Users vs. a Perioperative Limited Prescription on Oxycodone Requirement

• Status: Completed
• Trial end date: 2017-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Spinal surgery is associated with intense pain and associated to a history of preoperative chronic pain. Pregabalin is licensed to treat chronic neuropathic pain, particularly when high dose of opioid are required. Preoperative pain is associated with high postoperative pain scores and opioid requirement promoting persistent hyperalgesic state. The investigators will evaluate the postoperative opioid consumption and pain scores in patients scheduled for lumbar surgery and taking pregabalin since more than 15 days and compare with preoperative pregabalin-free patient that will receive pregabalin only during surgery.
