The object of our research is to investigate the relative efficacy of liposomal bupivacaine
administered via an Erector Spinae Plane (ESP) block as compared to our standard of care
medication solution of (bupivacaine mixed with epinephrine, dexamethasone, and clonidine) for
pain management in subjects undergoing bilateral surgical intervention for breast cancer.
This will be an investigator-initiated, double-blind, patient-controlled, randomized control
trial comparing pain scores at 48 hours after injection.
