Background: Methods and efficacy of nasal anesthesia before ultrathin transnasal EGD (UT-EGD) are crucial for patient tolerance.
Objective: To compare patient tolerance, safety, and adverse events between cotton-tipped applicator primed gauze pledgetting (CTGP) and endoscopic-guided aerosolized spray (EGAS) methods of nasal anesthesia.
Design: We performed a prospective, randomized-controlled trial to compare procedural discomforts, optical quality, total procedure time, and adverse events between the CTGP and EGAS methods.
