Randomized Controlled Trial Comparative StudyEfficacy and safety of high-concentration adrenaline wicks during functional endoscopic sinus surgery.
Epinephrine is a commonly used vasoconstrictor for instillation or infiltration to limit bleeding and improve the quality of the surgical field in functional endoscopic sinus surgery (FESS). No study to date has shown the efficacy of varying concentrations of adrenaline wicks into the nasal mucosa during FESS. ⋯ High-concentration (4 mg in 20 mL of saline) adrenaline wicks used during FESS significantly improve the quality of the surgical field and decrease blood loss compared to low-concentration (1 mg in 20 mL saline) wicks. Associated hemodynamic changes can be controlled in both groups without significant clinical consequences.

Randomized Controlled Trial Comparative StudyPain and discomfort during flexible nasolaryngoscopy: a randomized, controlled trial assessing the efficacy of oral mouthwash and topical lidocaine.
To test the hypothesis that using Listerine mouthwash prior to administration of topical nasal lidocaine will result in improved pain and comfort outcomes during flexible nasolaryngoscopy (FNL). ⋯ Using Listerine prior to application of lidocaine nasal spray reduces the pain and discomfort of FNL. This effect was most clinically significant in patients undergoing an extended or full bilateral nasal examination.
