INTRAOPERATIVE BLEEDING
Our primary outcome measure was to compare the amount of intraoperative bleeding (measured in ml) during external DCR using gauze soaked with combined TXA (100 mg/ml) and epinephrine 1:200,000 versus using gauze soaked only with epinephrine 1:200,000.Secondary outcome measures were to report the number of used gauzes in each group, measure surgical time, and assess the degree of surgeon satisfaction regarding the clarity of the surgical field and the ease of the surgery.
