Multimodal analgesia may be important for optimal postoperative pain treatment and facilitation of early mobilization and recovery. This study investigated the analgesic effect of pregabalin and dexamethasone in patients undergoing lumbar spinal surgery.

Condition Intervention
Drug: Pregabalin
Drug: dexamethasone
Drug: placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Double Blind (Care Provider, Investigator)
Primary Purpose: Supportive Care

Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • the multimodal analgesic effect of pregabalin, and of pregabalin with dexamethasone [ Time Frame: Assessment was performed during the first 72 hour following emergence from general anesthesia, subdivided into 5 time periods; on arrival of patient to the PACU, 1-6 hour, 6-24 hour, 24-48 hour and 48-72 hour ]
    Primary Outcome is to investigate the multimodal analgesic effect of pregabalin, and of pregabalin with dexamethasone, in patients receiving a patient-controlled analgeisa with fentanyl, on fentanyl consumption (primary end point), pain scores and side effects in patients scheduled for lumbar spinal surgery.
