Randomized Controlled TrialA randomized trial of buffered versus nonbuffered lidocaine with epinephrine for cervical loop excision.
Our study evaluated whether buffering reduces pain from lidocaine injection for loop electrosurgical excisional procedures (LEEPs) of the cervix when compared to unbuffered lidocaine. ⋯ Pain scores with subepithelial lidocaine plus epinephrine for LEEP are low and are not significantly reduced by buffering the anesthetic.
