Background
Nowadays, minimizing the surgical complications of rhinoplasty has gained more importance. Results from previous trials show that Tranexamic acid (TXA) reduces intraoperative bleeding, one of the major complicating factors during rhinoplasty.
Objective
To contribute to previous evidence by re-evaluating the efficacy of TXA, specifically in reducing intraoperative blood loss and increasing surgical field quality in rhinoplasty.
Study Design and Methods
A randomized placebo-controlled trial was conducted (IRCT20111219008458N2). The outcomes included total intraoperative blood loss, measured by the total volume of fluid collected by suction and gauzes, subtracted by volume of used irrigation fluids, and the quality of surgical field, measured by surgeon’s satisfaction on a 5-point Likert scale. Demographics, blood coagulation measures, and clinical data were also collected and were held as covariates in analysis. After blinding, randomization, and group allocations, the intervention group received TXA 10mg/kg and the placebo group normal saline in equal volumes.
Results
Data of a total of 80 patients were gathered and analyzed. The total intraoperative blood loss was insignificantly lower (mean difference [95% CI]: − 3.6 ( − 19.19, 11.99), P = 0.65) and surgeon’s satisfaction was insignificantly higher (mean difference [95% CI]: 0.18 ( − 0.11, 0.46), P = 0.22) in TXA group. Results were confirmed by multivariable analysis.
Conclusion
In contrast to most of the previous studies, this study showed only a statistically insignificant decrease in total intraoperative blood loss in patients receiving TXA compared to placebo. Further studies are required to more precisely estimate the efficacy of TXA in reducing blood loss during rhinoplasty.
