Intravenous tranexamic acid use in myomectomy: A prospective randomized double-blind placebo controlled study

Objective: To define the effect of tranexamic acid use on perioperative and postoperative bleeding and blood transfusion requirements in women undergoing myomectomy. Study design: Among the patients that underwent myomectomy a total of 100 cases were included in the study. The patients (n = 50) randomized to receive tranexamic acid were defined as Group I and those receiving saline were defined as Group II. Perioperative blood loss was calculated by measuring the volume in the suction apparatus and weighing the swabs. Postoperative blood loss was defined as the blood volume found in the subfascial suction drain. The two groups were compared for age, body mass index, basal hemoglobin and hematocrit. basal parameters of coagulation, the number and the volume of myomas removed, peri- and postoperative and total blood loss, duration of surgery and blood transfusion requirements. Results: No significant difference was found between the two groups when compared age, body mass index, preoperative blood analysis, the number and volume of myomas removed. Statistically significant differences were found between the two groups when compared for postoperative and total blood loss and duration of surgery (p < 0.01, p = 0.03 and p = 0.03, respectively). Perioperative blood loss and blood transfusion requirements were similar between the two groups (p = 0.12 and p = 0.25, respectively). There were no complications in either group. Conclusion: Our study is the first in the literature evaluating the effectiveness of tranexamic acid use on peri- and postoperative bleeding in gynecological surgery. No additional benefit of intravenous infusion of tranexamic acid was found. Tranexamic acid does not seem to be a useful adjunct in myomectomy if given according to the described protocol in this study. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
