PURPOSE: To evaluate the efficacy of topical tranexamic acid (TXA) in reducing intraoperative and immediate postoperative bleeding during functional endoscopic sinus surgery (FESS) among patients with chronic rhinosinusitis with nasal polyposis (CRSwNP).
METHODS: This is a double-blind randomized clinical trial, involving 26 patients with CRSwNP, who underwent FESS for failed medical therapy. The intervention nostril was packed with ribbon gauze soaked in 500 mg/5 ml TXA. The control nostril was packed with ribbon gauze soaked in Moffett's solution, containing 2 ml 10% cocaine, 1 ml adrenaline 1:1000, and 4 ml 0.9% sodium bicarbonate. Both nostrils were packed for 15 min before FESS. Intraoperative bleeding was recorded in the initial 30 min after commencing the surgery. The recordings were reviewed by two surgeons using Boezaart's scoring system. The scores were taken at 15 and 30 min of surgery. The mean score was then calculated. At the end of the surgery, the intervention nostril was packed with Merocel® soaked in 500 mg/5 ml TXA and the control nostril was packed with Merocel® soaked in normal saline. The amount of bleeding within 24 h post-surgery was evaluated using a bolster gauze.
RESULTS: There was no significant difference in intraoperative bleeding between the intervention (1.54 ± 0.71) and control nostrils (1.69 ± 0.55) with p = 0.172. The amount of bleeding in the postoperative period was significantly reduced in the intervention nostril (1.33 ± 0.55) compared to the control nostril saline (1.81 ± 0.48) with p = 0.001.
CONCLUSIONS: We found that the nasal packing soaked in TXA reduced intraoperative and immediate postoperative bleeding. It is a safe, efficacious and cost-effective alternative to Moffett's solution during FESS and also an alternative to normal saline post-surgery among patients with CRSwNP.
