2. A typical dose range for perioperative gabapentin is 200-300 mg and 25-50 mg for pregabalin. 3. Given the opioid-sparing effect of gabapentinoids, lower doses of perioperative narcotics may be used. 4. While the benefits of perioperative gabapentinoids are well-documented, their use may This steady decrease in the mean pain score difference between gabapentin and placebo may be attributed to the reported half-life of gabapentin, which is around 7 hours. 39 The overall reduction in pain score in the current review was comparable to an earlier review examining the efficacy of gabapentin in spinal surgery. 18 Yu L, Ran B, Li M, et al.

Hwang SH, Park IJ, Cho YJ, et al. The efficacy of gabapentin/pregabalin in improving pain after tonsillectomy: a meta-analysis. The administration of gabapentin is effective in decreasing postoperative narcotic consumption and the VAS score. Keywords: Gabapentin, Total hip arthroplasty, Meta-analysis. Background. Total hip arthroplasty (THA) is a common and successful surgery in modern medicine, but it is often associated with intense postoperative pain . Pre-emptive undergoing elective or emergent surgery under any type of anesthesia were considered. Included trials had to evaluate gabapentinoids (pregabalin or gabapentin) initiated between 1 week before and 12h after surgery. At least one outcome measure had to be assessed to be considered for inclusion. Their findings, recently published in the journal Anesthesiology, indicate that the analgesic benefits of pregabalin and gabapentin after surgery are negligible, regardless of the dose or type of operation. Gabapentinoids were also ineffective in preventing chronic pain from developing after surgery, one of the primary justifications for using In this cohort study, perioperative gabapentin use was associated with increased risk of delirium, new antipsychotic use, and pneumonia among older patients after major surgery. These results suggest careful risk-benefit assessment before prescribing gabapentin for perioperative pain management. 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. 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. Recent findings: Recent meta-analyses have revealed that prior data likely have overestimated the beneficial effects of gabapentinoids in acute perioperative pain while underestimating the associated adverse effects. 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 CONCLUSIONS: Gabapentinoids effectively reduce postoperative pain, opioid consumption, and opioid-related adverse effects after surgery. Conclusions about the optimal dose and duration of the treatment cannot be made because of the heterogeneity of the trials. 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 The observed reduction in postoperative opioid consumption with preoperative gabapentin supports the notion of incorporating gabapentin in the multimodal analgesic treatment plans for postoperative pain management among patients undergoing elective surgery. In the absence of either criteria, discontinue prior to surgery. Irreversible MAO antagonists may require 2 weeks after discontinuation of drug for normal MAO function to return. Therefore these medications should be tapered and discontinued two weeks before elective surgery. They found that gabapentin resulted in a 35% reduction in total analgesic consumption in the first 24 hours following surgery. Gabapentin also resulted in 27% to 39% reduction in visual analog scale (VAS) pain scores in the first 24 hours postoperatively. First, we repeated the analysis by defining gabapentin exposure on the day of surgery without requiring a 2-day minimum length of stay after surgery. Then, we explored a dose-response relationship using a 4-dose category of gabapentin (no use, 1 mg to <600 mg, 600 mg to <1200 mg, or ≥1200 mg). For example, in this study, 5 80% of gabapentin users received gabapentin on the day of surgery, suggesting that it was started prior to any patient report of pain, representing an opportunity to de-escalate gabapentin use for some patients. Second, engaging patients and caregivers in their care could allow us to better manage expectations for While gabapentin may have some benefit in the short-term and some older adults may have persistent pain that warrants prolonged use of gabapentin, particularly after spinal surgery, we speculate that a large proportion of this prolonged use is not intentional, and that the system needs to be improved to prevent both polypharmacy and 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.
