The Effect of Buffered Lidocaine Versus Nonbuffered Lidocaine on Pain Scores During Infiltration for Vulvar Biopsies

Objective: To compare pain scores on a visual analogue scale during infiltration of local anesthetic for vulvar biopsies between women who are treated with buffered versus non- buffered lidocaine Hypothesis: Patients treated with buffered lidocaine at the site of vulvar biopsy will have lower pain scores on a visual analogue scale during the biopsy. Study Design: Double blinded randomized controlled trial Population: Women undergoing vulvar biopsy at the Women's Primary Care Center and The Program In Women's Oncology Clinic of a non-infectious vulvar lesion.
