PEMF and PEC Blocks in Mastectomy Reconstruction Patients

Chronic pain after mastectomy, or breast tissue removal, is very common with almost half of women experiencing some type of residual pain and even 13% characterizing it as severe. Poor acute postoperative pain control is not only associated with development of chronic pain, but has also been shown to be associated with delayed wound healing. Therefore, optimization of postoperative pain control is paramount not just for patient comfort, but to decrease immediate and long-term postoperative complications.

There are two adjunctive modes of perioperative pain control currently in use at Columbia University Medical Center (CUMC). The first mode uses pulsed electromagnetic fields (PEMF) and consists of a noninvasive device placed over dressings around the surgical site. The second is a regional anesthetic and -the pectoral interfascial block (PIB) in which a long-lasting local anesthetic (bupivacaine/ropivacaine) is injected into the surgical dissection area. Both of these techniques for postoperative analgesia have been shown to be effective in different types of breast surgery, but there is no current literature comparing the two modalities in their efficacy in reducing postoperative pain. There is also no current literature in their efficacy in the mastectomy and tissue expander patient population. The proposed trial is a prospective, randomized, controlled, double-blind trial to evaluate the efficacy of these two modalities of postoperative analgesia in patients undergoing mastectomy and tissue expander reconstruction.
