BackgroundThe effect of tranexamic acid (TXA) on bleeding and improvement of surgical field during functional endoscopic sinus surgery (FESS) is not clear yet. This study was conducted to answer this question.MethodsThis trial was conducted on 60 patients with chronic sinusitis at Beasat Hospital, Hamadan, Iran, from April to November 2013. Thirty patients in the intervention group received three pledgets soaked with TXA 5% and phenylephrine 0.5% for 10 minutes in each nasal cavity before surgery. Thirty patients in the control group received phenylephrine 0.5% with the same way. The amount of bleeding and the quality of surgical field were evaluated at 15, 30, and 45 minutes after the start of surgery using Boezaart grading.ResultsThe quality of the surgical field in the intervention group compared to the control group was significantly better in the first quarter (P = 0.002) and the second quarter (P = 0.003) but not in the third quarter (P = 0.163). Furthermore, the amount of bleeding was much less during all periods in the intervention group than in the control group (P = 0.001).ConclusionTopical TXA can efficiently reduce bleeding and improve the surgical field in FESS in patients with rhinosinusitis. Based on these findings, topical TXA may be a useful method for providing a suitable surgical field during the first 30 minutes after use.Trial RegistrationIranian Registry of Clinical Trials IRCT201212139014N15.
