To assess whether bipolar sealer has advantages over standard electrocautery in primary total hip arthroplasty (THA).
All studies published through November 2013 were systematically searched in PubMed, Embase, ScienceDirect, The Cochrane Library, and other databases. Relevant journals or conference proceedings were searched manually. Only randomized controlled trials were included. Two independent reviewers identified and assessed the literature. Mean difference in blood loss and risk ratios of transfusion rates and of complication rates in the bipolar sealer group versus the standard electrocautery group were calculated. The meta-analysis was conducted using RevMan 5.1 software.
Five studies were included, with a total sample size of 559 patients. The use of bipolar sealer did not significantly reduce intraoperative blood loss, hemoglobin drop, hospital stay, and operative time. There were no significant differences in need for transfusion and the incidence of infection between the study groups.
The available evidence suggests that the use of bipolar sealer was not superior to standard electrocautery in patients undergoing primary THA. The use of bipolar sealer is not recommended in primary THA.
评估双极电凝器在初次全髋关节置换术（THA）中是否比标准电烙术更具优势。
对截至2013年11月发表的所有研究在PubMed、Embase、ScienceDirect、Cochrane图书馆及其他数据库中进行系统检索。手动检索相关期刊或会议论文集。仅纳入随机对照试验。两名独立评审员对文献进行识别和评估。计算双极电凝器组与标准电烙术组在失血量、输血率及并发症发生率方面的平均差异和风险比。使用RevMan 5.1软件进行荟萃分析。
纳入五项研究，样本总量为559例患者。使用双极电凝器并未显著减少术中失血量、血红蛋白下降、住院时间及手术时间。研究组之间在输血需求和感染发生率方面无显著差异。
现有证据表明，在接受初次THA的患者中，双极电凝器的使用并不优于标准电烙术。不建议在初次THA中使用双极电凝器。
