Gabapentin is a novel drug used for the treatment of postoperative pain with antihyperalgesic properties and a unique mechanism of action, which differentiates it from other commonly used drugs. Various studies have shown that perioperative use of gabapentin reduces postoperative pain. We recommend being selective with regard to using gabapentinoids for acute postoperative pain management after careful consideration of the potential side effect profile based on patient comorbidities as well as the expected severity of postoperative pain. Gabapentin is commonly indicated in the treatment of seizures. 27 Gabapentin, which acts on the nociceptive processes involved in central sensitization, has been shown to reduce hypersensitivity associated with nerve injury (hyperalgesia) and postoperative pain and inflammation in animal models. 28 Interestingly, gabapentin’s antiemetic Perioperative use of gabapentin has a significant 24-hour opioid sparing effect and improves pain score for both abdominal hysterectomy and spinal surgery. Nausea may be reduced in abdominal hysterectomy. Perioperative gabapentin, 1200 mg, administered preoperatively plus 600 mg every 8 hours continued for 72 hours after surgery did not affect time to pain cessation, the rate of pain resolution, or the proportion of patients with chronic pain at 6 months or 1 year following surgery. 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. Gabapentin 250 mg is statistically superior to placebo in the treatment of established acute postoperative pain, but the NNT of 11 for at least 50% pain relief over 6 hours with gabapentin 250 mg is of limited clinical value and inferior to commonly used analgesics. • Gabapentinoids such as gabapentin and pregabalin are often included in perioperative multimodal analgesia regimens in an attempt to reduce acute, subacute, and chronic pain after surgery • Current American Pain Society and European Society of Regional Anaesthesia and Pain Therapy guidelines offer conflicting recom- Pain management after total hip arthroplasty (THA) varies and has been widely studied in recent years. Gabapentin as a third-generation antiepileptic drug that selectively affects the nociceptive process has been used for pain relief after THA. This In addition, because pain intensity may be an unmeasured confounder of the association between gabapentin use and delirium, we examined how the RR estimate would change under various scenarios: (1) the prevalence difference in severe pain between gabapentin users and nonusers and (2) the relative risk between severe pain and delirium from the The findings contradict guidelines published by the American Pain Society (APS) in 2016, which advocate “around the clock” use of gabapentin, pregabalin and other nonopioid drugs both before and after surgery. Perioperative gabapentin upped the risk of delirium, new antipsychotic use, and pneumonia in older adults after major surgery, a retrospective study showed. This work was to examine the evidence of the gabapentin systematically and make a comprehensive understanding of the efficacy and safety of gabapentin in the management of postoperative pain after TKA. The use of gabapentin before surgical incision showed an overall cumulative reduction of pain score, in the first 24 hours after surgery, by an average of 1.04 (0-10 pain scale) in comparison to placebo (MD, –1.04; 95% CI, –1.45 to –0.63; P < .00001). A combination of therapies and medications will be used together for better pain control after your surgery. How do I know what to take to feel better? When you go home, your pain plan may have you start with a combination of non-medication therapies and non-opioid medications. Hah et. al. reported that in a randomized clinical trial of 410 patients undergoing a variety of surgeries (294 of which were orthopedic surgeries), patients given 1200 mg gabapentin preoperatively and 600 mg three times daily postoperatively for three days, demonstrated a 24% increase in the rate of opioid cessation after surgery. 27 Menigaux 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 Peri-operative gabapentin administration is effective in reducing pain scores, opioid requirements and opioid-related adverse effects in the first 24 hours after surgery. No serious side-effects were observed, though sedation was associated with gabapentin use. Gabapentin and other anticonvulsant medications have been established as an effective treatment for chronic neuropathic pain and are commonly used for such conditions as herpetic neuralgia, diabetic neuropathy, and phantom limb pain following amputation.
