Effects of Topical Lidocaine and Benzocaine on Pain Level and Injection Satisfaction

This study aimed to evaluate the effectiveness of topical lidocaine and benzocaine in reducing pain and improving injection satisfaction during AVF catheterization among hemodialysis patients. Design:A randomized controlled trial was conducted with 60 hemodialysis patients who met the inclusion criteria. Methods: Participants were randomly assigned into three groups: Lidocaine Spray (n=20), Benzocaine Spray (n=20), and Placebo (n=20). Pain intensity and injection satisfaction were measured immediately after catheterization using the Visual Analogue Scale (VAS) and the Injection Satisfaction Scale (ISS).
