Arnica Montana and Blood Loss, Surgical Field Bleeding and Operative Time in Endoscopic Sinus Surgery: A Randomized-Controlled Trial

Methods: Design: Single-Blinded Randomized Controlled Trial Setting: Tertiary Government Hospital Participants: Forty-one (41) adults aged 19-76 years old with chronic rhinosinusitis with nasal polyposis and meeting inclusion criteria were randomly divided into two groups, Arnica and control. The former took 5 sublingual Boiron® Arnica montana 30C pellets, 12 hours then 1 hour prior to surgery; the latter did not. Both groups had routine oxymetazoline and lidocaine-epinephrine decongestion. Intraoperative blood loss, surgical field bleeding quality and operative time were assessed by blinded surgeons and anesthesiologists.
