骨折患者切开内固定术围术期使用不同疗程抗菌药物预防感染的Meta分析

摘要

目的:系统评价骨折患者切开内固定术围术期应用单剂量与多剂量抗菌药物预防手术部位感染的疗效,为临床提供循证参考.方法:计算机检索PubMed、EMBase、Corchrane图书馆、中国生物医学文献数据库、中国期刊全文数据库、中文科技期刊数据库和万方数据库,查找闭合性骨折患者行切开内固定术治疗后,围术期应用单剂量(试验组)与多剂量(对照组)抗菌药物预防手术部位感染的随机对照试验(RCT),筛选文献、提取资料并按照改良的Jadad评分量表评价质量后,采用Rev Man 5.3统计软件进行Meta分析.结果:最终纳入8项RCT,合计3 457例患者.Meta分析结果显示,两组患者手术部位感染率比较,差异无统计学意义.[OR=1.02,95％ CI (0.63,1.66),P=0.94].依据用药不同选择使用头孢唑啉的研究进行亚组分析,Meta分析结果显示,手术部位感染率比较,差异仍无统计学意义[OR=1.33,95％ CI (0.55,3.20),P=0.52].结论:闭合性骨折行切开内固定术治疗患者,围术期推荐单剂量预防性应用抗菌药物.%OBJECTIVE:To systematically evaluate therapeutic efficacies of perioperative application of single-dose and multipie-dose of antibiotics for preventing surgical site infection after closed fractures patients receive incision and internal fixation,and to provide evidence-based reference.METHODS:Retrieved from PubMed,EMBase,CBM,Cochrane Library,CBM,CJFD,VIP and Wanfang database,RCTs about perioperative application of single-dose (trial group) and multiple-dose (control group) of antibiotics for preventing surgical site infection after closed fractures patients receive incision and internal fixation were collected.Meta-analysis was performed using Rev Man 5.3 statistical software after literature screening,data extraction and quality evaluation by improved Jadad.RESULTS:Finally 8 clinical studies were included,involving 3 457 patients.The results of Meta-analysis showed that there was no statistical significance in the rate of surgical site infection [OR=1.02,95％ CI(0.63,1.66),P=0.94)].Cefazolin stadies were included in subgroup analysis according to drug use,and results of Meta-analysis showed that there was no statistical significance in the rate of surgical site infection[OR=1.33,95％CI(0.55,3.20),P=0.52].CONCLUSIONS:Prophylactic application of single-dose of antibiotics is recommended for preventing surgical site infection after closed fractures patients receive incision and internal fixation.
