Background According to recent evidence, the use of local tranexamic acid (TXA) during plastic surgery may lessen blood loss. Objectives To comprehensively assess the use of local TXA during plastic surgery through a systematic review and meta-analysis of randomized controlled trials addressing these issues. Methods Four electronic databases, including PubMed, Web of Science, Embase and the Cochrane Library, were searched until December 12, 2022. Following meta-analyses, the mean difference (MD) or standardized mean difference (SMD) for blood loss volume (BLV), ΔHct, ΔHb and operation time were calculated when appropriate. Results Eleven randomized controlled trials were included in the qualitative synthesis, while 8 studies were included in the meta-analysis. Compared with the control group, the local TXA group showed a reduction in blood loss volume of -1.05 (p < 0.00001; 95% CI, −1.72 to −0.38). However, local TXA had a limited effect on reducing ΔHct, ΔHb and operation time. A meta-analysis was not performed because of heterogeneity in other outcomes; however, except for 1 study in which no significant difference was observed on POD 1, all studies showed significantly lower rates of postoperative ecchymosis after surgery, 2 studies showed statistically significant reductions in transfusion risk or volume, and 3 studies reported significantly better surgical field quality in operations with local TXA. In the 2 included studies, the researchers concluded that local treatment does not play a role in relieving postoperative pain. Conclusions Local TXA is associated with less blood loss, less ecchymosis and better surgical field in plastic surgery patients.
