We compared the efficacy of tranexamic acid (TXA) and clonidine in reducing blood loss and improving surgical field visualization during FESS.   Materials and Methods: In a double-blind, randomized, clinical trial, 52 patients, American Society of Anesthesiologists (ASA) physical status 1–2, aged 13–75 years, suffering from rhinosinusitis with or without polyposis, and who were candidates for FESS, were enrolled. The first group received intravenous TXA 15 mg/kg diluted in 100 ml normal saline, administered during 10-min infusion after induction. In the second group, 0.2 mg oral clonidine was given 1 to 1.5 hours before surgery. Duration of surgery, hemoglobin level, heart rate, blood pressure, and quality of surgical field based on Boezzart's scale and surgeon satisfaction based on Likert's scale were recorded in both groups.   Results: In total, 52 patients, 27 (51.9%) males and 25 (48.07%) females were studied. Twenty-two (42.3%) and 30 (57.7%) were in the TXA and clonidine groups, respectively. The mean pre- and post-surgical hemoglobin level showed no meaningful difference between the two groups. The same result was obtained for blood pressure and heart rate at different time points (P>0.05). Mean anesthesia time (P=0.859), mean surgical time (P=0.880), surgeon's satisfaction of the surgical field (P=0.757) and surgical field quality at different time points revealed no significant difference between the two groups.   Conclusion: Premedication with oral clonidine and intravenous TXA has the same effect on bleeding during FESS, surgical field visualization, and surgeon satisfaction.
