摘　　要：目的通过Meta分析,以系统评价的方法探究肌肉收缩舒张练习(applied muscle tension,AMT)对减少血管迷走神经反应(vasovagal reactions,VVRs)的效果。方法以“applied muscle tension”、“vasovagal reactions”等为关键词搜索MEDLINE、Web of Science、CINAHL等9个相关数据库,收集在献血期间应用AMT练习对VVR反应效果的临床研究。由2位研究人员按照制定的纳入和排除标准,独立对所检索的文献进行筛选、质量评价和资料提取,使用RevMan5.4统计软件对所提取的数据进行Meta分析。结果最终纳入7篇文献,其中英文5篇,中文2篇,共6808名无偿献血者。试验组为献血过程中进行AMT练习,对照组为不进行AMT练习。与对照组相比,AMT练习组在降低VVRs发生率[RR=0.60,95%CI(0.42,0.87),P<0.01]方面的差异有统计学意义。结论AMT练习能够有效降低献血过程中的VVRs发生率,但由于目前所纳入研究的证据质量有限,未来还需要前瞻性、多中心、大样本量的高质量研究进一步验证。Objective To systematically evaluate the effect of applied muscle tension(AMT)exercises on reducing vasovagal reactions(VVRs)among blood donors by meta-analysis.Methods Nine related databases including MEDLINE,Web of Science and CINAHL were searched using"applied muscle tension"and"vasovagal reactions"as keywords to collect clinical studies on the effects of AMT exercise on VVRs during blood donation.Two researchers independently screened,evaluated the quality and extracted data from the retrieved literature according to the inclusion and exclusion criteria.RevMan 5.4 was used to conduct meta-analysis on the extracted data.Results A total of 7 articles were finally included,5 in English and 2 in Chinese,covering 6808 blood donors.The experimental group performed AMT during blood donation,while the control group did not.Compared with the control group,the difference in reducing the incidence of VVRs[RR=0.60,95%CI(0.42,0.87),P<0.01]was statistically significant in the AMT group.Conclusion AMT can effectively reduce the incidence of VVRs during blood donation.However,due to the limitation in the included studies,high-quality studies with perspectiveness,multicenter,large-sample size are further needed for validation in the future.
