For the third serial Group in the study, patients electing to undergo breast reduction surgery will be invited to participate in the study at their preoperative visit. For the fourth Group in the study, all procedures will be the same as described in this section, but the patients will be undergoing breast augmentation surgery (not breast reduction). All patients choosing to take part in the study will be consented prior to their procedure. The study participants will be randomized, using block randomization, a computer-generated randomization template, and sealed, numbered, and opaque envelopes, to either receive (a) perioperative pain, nausea, and recovery strategies as part of our Enhanced Recovery after Breast Surgery (ERABS) protocol, or (b) perioperative instructions, anesthesia and medications as per our institution's current standard of care for elective breast reduction or breast augmentation.
