Abstract

BACKGROUND Perioperative haemorrhage is an important concern during any surgical procedure. The purpose of this study was to assess the effect of tranexamic acid (TXA) irrigation on perioperative haemorrhage during the surgical removal of impacted mandibular third molar. METHODS In this double-blind, randomized controlled clinical trial, 120 participants who underwent surgical removal of horizontally impacted mandibular third molar were divided into 2 groups. The patients in the Group 1 received 0.9 % normal saline for irrigation during the procedure and the patients in the Group 2 received TXA irrigation with normal saline (1 mg / mL), age, gender, operation duration, amount of blood loss and visual assessment of surgical field were the variables that were studied. The use of TXA solution for irrigation was the predictive factor of the study. RESULTS Each group consisted of 60 patients. Group 1 consisted of 31 male patients (51.7 %) and 29 female patients (48.3 %) and group 2 consisted of 30 male patients (50 %) and 30 female patients (50 %). There was no difference in the distribution of the variables between the 2 groups, except for the duration of the operation. The mean operative time was 20.94 ± 0.61 minutes in group 1 and 26.17 ± 0.98 minutes in group 2 (P > .05) which was not statistically significant. The mean intraoperative blood loss was 44.47 ± 6.416 mL in group 1 and 84.73 ± 7.861 in group 2 (P < .05). The mean volume of irrigation was 100.08 ± 7.658 mL in group 1 and 140.33 ± 12.332 mL in group 2 (P < .05). CONCLUSIONS TXA is effective in reducing the risk of intraoperative blood loss in patients for whom substantial blood loss is anticipated.
