The pregabalin effect on opioid consumption and postoperative pain in spinal fusion surgery, a prospective, randomized, controlled study
Background and AimSurgical trauma is known to cause peripheral and central sensitization and hyperalgesia, which if untreated can cause chronic postoperative pain after surgery. The current work was conducted to evaluate the effect of preoperative pregabalin 150 mg orally on opioid consumption and acute postoperative pain in spinal fusion surgery.MethodsOver one-year duration between 2020 and 2021, the current study was conducted. Ninety patients who were scheduled for spinal fusion surgeries (single and double levels) were recruited and randomly subdivided into two equal groups who received either pregabalin or placebo. The primary outcome was the overall amount of consumed morphine in the first 24 hours postoperatively. Secondary outcomes included VAS score at 1 hour, 2 hours, 4 hours and 24 hours postoperative, time to first rescue analgesia and vital signs including heart rate and mean arterial blood pressure intra- and postoperatively.
