Abstract
BackgroundPregabalin may have some potential in alleviating pain after thoracic surgery, and this meta-analysis aims to explore the impact of pregabalin on pain intensity for patients undergoing thoracic surgery.MethodsPubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of pregabalin on pain intensity after thoracic surgery.ResultsFive RCTs were finally included in the meta-analysis. Overall, compared with control intervention for thoracic surgery, pregabalin was associated with significantly reduced pain scores at 0 h (mean difference [MD]=-0.70; 95% confidence interval [CI]=-1.10 to -0.30; P = 0.0005), pain scores at 24 h (MD=-0.47; 95% CI=-0.75 to -0.18; P = 0.001) and neuropathic pain (odd ratio [OR] = 0.24; 95% CI = 0.12 to 0.47; P < 0.0001), but demonstrated no obvious impact on the incidence of dizziness (OR = 1.07; 95% CI = 0.15 to 7.46; P = 0.95), headache (OR = 1.00; 95% CI = 0.30 to 3.35; P = 1.00) or nausea (OR = 1.24; 95% CI = 0.46 to 3.35; P = 0.68).ConclusionsPregabalin may be effective to alleviate the pain after thoracic surgery.
