Topical combined tranexamic acid and epinephrine versus topical epinephrine in control of intraoperative bleeding of external dacryocystorhinostomy.

External DCR using gauze soaked with combined TXA (100 mg/ml) and epinephrine 1:200,000 showed a significant reduction in the amount of intraoperative bleeding compared to gauze soaked with epinephrine 1:200,000 only. The reduction in the amount of bleeding with the addition of TXA resulted in clearer surgical field, shorter surgical time and more surgeon satisfaction.Query.
