More recently, studies on animal models of acute pain have indicated a role of gabapentin in ameliorating pain from incisional injury and arthritis (7,8), implicating even broader use of gabapentin in treating a variety of pain states. In summary, the administration of gabapentin was effective in decreasing postoperative narcotic consumption and the incidence of pruritus. There was a high risk of selection bias and a higher heterogeneity of knee flexion range in this analysis. Various studies have shown that perioperative use of gabapentin reduces postoperative pain. Gabapentin works by reducing lesion-induced hyperexcitability of posterior horn neurons, which is responsible for central sensitization . The purpose of this review is to critically appraise the evidence for the use of gabapentinoids for acute pain management and its impact on the development of chronic pain after surgery. Recent findings: Recent meta-analyses have revealed that prior data likely have overestimated the beneficial effects of gabapentinoids in acute perioperative 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. Like other anticonvulsant drugs, gabapentin has been studied for the additional potential benefit of analgesia in models of neuropathic pain. 29 More recently, evidence has been collected supporting the potential efficacy of gabapentin in blocking other pain pathways, surgical and inflammatory pain being 2 such examples. 9,10 Although the Gabapentin 900 or 1200 mg, administered either pre- or post-incision, was found to be effective in pain management following lumbar laminectomy. Similar doses of gabapentin provide the same post-operative analgesia whether administered pre- or post-incision. Background: Perioperative pain treatment often consist of combinations of non-opioid and opioid analgesics, 'multimodal analgesia', in which gabapentin is currently used. The aim was to document beneficial and harmful effects of perioperative gabapentin treatment. 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. Background Gabapentin is an antiepileptic drug used in a variety of chronic pain conditions. Increasing numbers of randomized trials indicate that gabapentin is effective as a postoperative analgesic. This procedure-specific systematic review aims to analyse the 24-hour postoperative effect of gabapentin on acute pain in adults. Methods Medline, The Cochrane Library and Google Scholar were cesarean delivery were randomized to receive preoperative gabapentin 600 mg, or placebo. Spinal anesthesia was achieved with 0.75% hyperbaric bupivacaine 12 mg, fentanyl 10 μg, and morphine 100 μg. Postoperative analgesia was initiated with intraoperative ketorolac and acetaminophen, and continued with postoperative diclofenac, acetaminophen, and morphine. Patients were assessed at 6, 12, 24 types of PAP: residual limb pain (RLP) and phantom limb pain (PLP), with an estimated 95% of people with ampu-tations experiencing one or both. MEDICAL MANAGEMENT: The majority of chronic PAP is due to phantom limb pain, which is neurogenic in na-ture. Common medications used include tricyclic anti-depressants, gabapentin, and opioids. Gabapentin, an anticonvulsant, has recently been suggested as an effective postoperative ‘analgesic’ agent. The objective of the present study was to examine the analgesic effectiveness, opioid-sparing effects and side effects associated with the use of gabapentin in a perioperative setting. significant post-sternotomy incisional pain, as well as pain from saphenous vein excision sites, and pericardiotomy and chest tube insertion points1-5. Prevention and management of this pain continues to be a major challenge and under-treatment of pain postoperatively persists despite good surgical outcomes. Inadequate pain control after cardiac Cesarean delivery occurs in roughly one third of pregnancies. Effective postoperative pain control is a goal for patients and physicians. Limiting opioid use in this period is important as some percentage of opioid naïve individuals will develop persistent use. Gabapentin is a non-opioid medication that has been used perioperatively to improve postoperative pain and limit opioid requirements NSAIDs are effective in animal models of inflammatory pain, while gabapentin is effective in animal models of neuropathic pain. The partial efficacy of both NSAIDs and gabapentin in the incisional pain model suggests that both inflammatory and neuropathic mechanisms contribute to the hyperalgesia and allodynia that is observed. is superior to another at the different rat models and tests. In the incisional pain model, there was partial efficacy of gabapentin. Our clinical data suggest that relative to the baseline pain score, the treatment with pregabalin at doses of 300 mg/day or gabapentin at doses of 900 mg/day would • 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- A meta-analysis of cesarean delivery under spinal anesthesia reported that gabapentin significantly reduced the pain score on movement at 24 h (mean difference −11.58, 95% CI −23.04 to −0.12). However, pain scores at other time points at rest or on movement were not significantly different . Gabapentinoid drugs—specifically gabapentin (Neurontin) and pregabalin (Lyrica)—are increasingly being prescribed for pain because physicians and patients seek alternatives to opioids in the
