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. 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. 60-70 yrs < 80 kg 25 mg 25 mg 70-80 yrs 80 kg 25-50 mg 25 mg 70-80 yrs < 80 kg 25 mg 25 mg 80+ yrs any 25 mg None- prescribe in PACU prn pain References: Verret M et al. Perioperative Use of Gabapentinoids for the Management of Postoperative Acute Pain A Systematic Review and Meta-analysis Anesthesiology 2020; 133:265–79 In 2006, Sihoe et al. evaluated gabapentin in the treatment of chronic pain after chest surgery (6). Twelve patients were chest trauma victims, 22 were status post video assisted thoracoscopic surgery (VATS), 8 had undergone open thoracotomies, and 3 had median sternotomies. Patients were started on a dose of gabapentin 300 mg daily Additionally, preemptive use of gabapentin 300 mg orally significantly alleviated postoperative pain two hours after internal fixation of the tibia. 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. Pre-emptive use of gabapentin 300 mg orally significantly decreases postoperative pain and rescue analgesic requirements in patients who undergo lower extremity orthopaedic surgery. In all the trials, gabapentin was administered preoperatively as a single oral dose or two divided doses 2–24 hours before surgery at a dose ranging from 300 mg to 1,200 mg. This study also identified an association between cumulative gabapentin dose and reduction in morphine consumption. Design, setting, and participants: Adults undergoing head and neck mucosal surgery from July 25, 2016, through June 19, 2017, were included in this double-blinded, placebo-controlled randomized clinical trial and randomized to receive gabapentin, 300 mg twice daily, or placebo before surgery and up to 72 hours after surgery. The aim was to document beneficial and harmful effects of perioperative gabapentin treatment. Methods: Randomized clinical trials comparing gabapentin vs. placebo or active placebo in adult surgical patients receiving gabapentin perioperatively were included. Gabapentin, an antiepileptic drug, is frequently used off-label to manage postoperative nerve pain due to its antiallodynic and antihyperalgesic properties. This article synthesizes research findings on the optimal dosage and efficacy of gabapentin for managing nerve pain after surgery. Pre-emptive use of gabapentin 300 mg orally significantly decreases postoperative pain two hours after surgery. After your surgery, begin taking 1 pill (300 mg) 3 times a day for the next 5 days; Depending on what time your surgery ends, start taking the Gabapentin at lunch or dinner; This medication may make you feel a little dizzy the first time you take it but this effect usually stops after the first dose or two Patients chose laparoscopic or open surgery and were then randomized to receive gabapentin 300 mg before surgery, then three times daily for 6 doses or placebo. There were 50 patients randomized to both the gabapentin and placebo groups for a total of 100 patients. Clarke 2009 Pre, Clarke 2009 HD, Clarke 2009 MD, and Clarke 2009 LD was the same trial, in which there were 5 groups, and we divided this trial into 4 different comparisons (gabapentin vs placebo preoperatively; gabapentin 300 mg vs placebo postoperatively; gabapentin 600 mg vs placebo postoperatively; and gabapentin 900 mg vs placebo To our knowledge, we report the results of the first randomized trial of perioperative use of gabapentin with extensive postoperative longitudinal follow-up and patient contact totaling 19 511 telephone calls up to 2 years after surgery. Perioperative gabapentin, 1200 mg, administered preoperatively plus 600 mg every 8 hours continued for 72 Pregabalin (n=30) and Gabapentin (n=30) 300 mg gabapentin or 75 mg pregabalin 1 h before surgery: There was a significant reduction in pain severity only at the first-time point between pregabalin and placebo treated patients (p=0.014). The pregabalin group required lower doses of opioids during admission. 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. Taking gabapentin before or after surgery may help reduce pain and decrease the need for opioid medications. In several studies, gabapentin was shown to lower pain after procedures like heart surgery, hysterectomy, and thoracic (chest) surgery. The doses of gabapentin used for surgical pain ranged from 300 mg to 1,200 mg, before and/or after
