  • Effect of warfarin on the risk of postoperative bleeding complications after tooth extractions: a meta-analysis

    Objective To systematically review the effect of discontinuous warfarin on the risk of postoperative bleeding complications after tooth extractions. Methods PubMed, EMbase, The Cochrane Library (Issue 9, 2016), CNKI, VIP, WanFang Data, China Food and Drug Administration and the ADR supervision system of FDA were electronically searched to collect randomized controlled trials (RCTs) and cohort studies about the effect of discontinuous warfarin on risk of postoperative bleeding complications after tooth extractions in patients until September 30th, 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results A total of 8 studies were included, involving 3 RCTs and 5 cohort studies. The results of meta-analysis showed that: there was no significant difference between the discontinuous or reduced warfarin group and the continuous warfarin group (RCTs: RR=0.86, 95%CI 0.49 to 1.51,P=0.60; cohort studies: RR=0.67, 95%CI 0.45 to 1.01,P=0.06). Conclusions Current evidence indicates that there is no statistically significant correlation between whether discontinuous warfarin and the risk of postoperative bleeding complications after tooth extractions. Due to the limited quantity and quality of included studies, the above conclusions are needed to be further verified by more high quality studies.
