Risk of delirium -- the primary outcome of the study -- was 3.4% for older patients who received gabapentin within 2 days after major surgery and 2.6% for those who did not, with a relative risk KEY WORDS: gabapentin, postoperative pain, cardiac sur-gery, coronary artery bypass graft surgery C RONARY ARTERY bypass graft (CABG) surgery is indicated to increase quality of life by reducing symptoms such as anginal pain. However, pain after CABG surgery may persist well after wound healing has taken place, and in some patients, chronic The Cleveland Clinic study had patients take a preemptive dose of three drugs: acetaminophen, the nerve pain medication gabapentin and the NSAID celecoxib (Celebrex). “Giving non-opioid pain medications before may help prevent the cascade of pain-causing chemicals that comes from your central nervous system after surgery,” explains Memtsoudis. This review evaluated the efficacy and tolerability of peri-operative gabapentin administration to control acute post-operative pain. Peri-operative gabapentin administration was found to be effective in reducing pain scores, opioid requirements and opioid-related adverse effects in the first 24 hours after surgery. Given the significant differences between the studies and the possibility of These findings indicate that preoperative use of gabapentin followed by postoperative dosing for two days did not significantly affect the postoperative pain, sleep, opioid consumption or patient-perceived quality of recovery for patients undergoing cardiac surgery. day trial, patients in the gabapentin group showed improved VAS pain scores and improved Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scores compared to patients in the naproxen group. In 2006, Sihoe et al. evaluated gabapentin in the treatment of chronic pain after chest surgery (6). This was a heterogeneous group of patients. Gabapentin and the related, more potent compound pregabalin have been shown to be beneficial in the treatment of neuropathic pain as well as postoperative pain following spinal surgery and hysterectomy. Gabapentin significantly reduced the intensity of pain and tramadol consumption in the early postoperative period after CABG surgery. Pain scores at 1 and 3 months after surgery were low in both groups, with no significant difference between the groups. We defined new postoperative gabapentin as fills for 7 days before surgery until 7 days after discharge. We excluded patients whose discharge disposition was hospice or death. The primary outcome was prolonged use of gabapentin, defined as a fill>90 days after discharge. Gabapentinoids were also ineffective in preventing chronic pain from developing after surgery, one of the primary justifications for using the drugs postoperatively. Similarly, aside from 24 h after surgery, gabapentin significantly reduced pain with movement (25–27,31,34,35,37,38) by 18% to 28% (VAS 8.2 mm to 10.2 mm) after surgery . The pooled effects on VAS pain scores displayed significant heterogeneity, which was not explained by subgroup analyses based on surgical procedure, gabapentin dose or study Purpose of review: This review summarizes the risks and benefits of gabapentinoids (gabapentin and pregabalin) for perioperative pain control and the controversies surrounding their use in a variety of settings. We review current literature with the goal of providing patient-centric and procedure-specific recommendations for the use of these The principal findings of this review are that gabapentin did not reduce postoperative opioid consumption after cardiac surgery; but may reduce pain scores at the expense of increased duration of mechanical ventilation. Nausea was decreased in gabapentin patients.30 Gabapentin can also be used as a beneficial adjunct to opioid analgesia after cardiac surgery. Paracetamol It may act by preventing prostaglandin synthesis, via increasing descending serotonergic impulses, which are antinococeptive, or by secondarily activating cannabinoid CB1 receptors. A significant number of RCTs have demonstrated conflicting results in the use of preoperative gabapentin. 19 Bharti et al 20 studied gabapentin administration among patients (n=40) undergoing mastectomy (20 received gabapentin and 20 received placebo) and demonstrated a reduction in the amount of morphine required during the initial 24 hours The main findings of this study were that a preoperative 600-mg single dose of gabapentin decreased total postoperative morphine consumption and the postoperative pain scores both at rest and with coughing after cardiac surgery. Gabapentin appears safe and well tolerated when used for persistent post-operative and post-traumatic pain in thoracic surgery patients, although minor side effects do occur. Gabapentin may relieve refractory chest wall pain in some of these patients, particularly those with more severe pain. This randomised controlled trial assigned 60 patients undergoing cardiac surgery to receive 1200 mg of gabapentin or placebo two hours preoperatively, and then 600 mg of gabapentin or placebo twice a day for the next two postoperative days. According to the International Association for the Study of Pain, PPP is defined as pain that persists beyond 3 months after surgery, can be continuous or intermittent, and is attributable to the surgical insult, excluding other potential etiologies. 4 Up to 43% of patients suffer PPP at 3 months after cardiac surgery. 1 A meta-analysis that
