Introduction:
To assess whether bipolar sealer has advantages over standard electrocautery in primary total hip arthroplasty (THA).
Methods:
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.
Results:
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.
Conclusion:
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.
