Review Meta AnalysisEfficacy and safety of perioperative pregabalin for post-operative pain: a meta-analysis of randomized-controlled trials.
We calculated in a meta-analysis the effect size for the reduction of post-operative pain and post-operative analgesic drugs, which can be obtained by the perioperative administration of pregabalin. Three end-points of efficacy were analysed: early (6 h-7 days) post-operative pain at rest (17 studies) and during movement (seven studies), and the amount of analgesic drugs in the studies that obtained identical results for pain at rest (12 studies). Reported adverse effects were also analysed. ⋯ Pregabalin increased the risk of dizziness or light-headedness and of visual disturbances, and decreased the occurrence of post-operative nausea and vomiting (PONV) in patients who did not receive anti-PONV prophylaxis. The administration of pregabalin during a short perioperative period provides additional analgesia in the short term, but at the cost of additional adverse effects. The lowest effective dose was 225-300 mg/day.
