Brief Summary
This is a prospective randomized controlled double-blind interventional study comparing the effect of pulsed-electromagnetic field device (PEMF), pectoral interfascial block (PIB), and placebo on postoperative pain control. This study has the interdisciplinary cooperation of the regional anesthesia group, and the breast and plastic surgery divisions. All female patients with breast cancer evaluated at Columbia University Medical Center (CUMC) who are undergoing unilateral or bilateral mastectomy with tissue expander reconstruction will be offered enrollment in this prospective study.

Outcome Measures
Primary Outcomes (2)
Score on Visual Analog Scale (VAS) - 1 Hour Post-intervention
Pain level will be measured using the VAS scale. Subjects will rate their pain level on a scale of 0-10. Number "0" indicates no pain and number "10" indicates terrible pain.
1 hour post-intervention
Score on Visual Analog Scale (VAS) - 3 Weeks Post-intervention
Pain level will be measured using the VAS scale. Subjects will rate their pain level on a scale of 0-10. Number "0" indicates no pain and number "10" indicates terrible pain.
3 weeks post-intervention
Secondary Outcomes (2)
Quality of Recovery Questionnaires (QoR) - 1 Hour Post-intervention
1 hour post-intervention
Quality of Recovery Questionnaires (QoR) - 3 Weeks Post-intervention

Study Arms (4)
Active PEMF + Treatment PIB
OTHERParticipants will receive an active device (Pulsed Electromagnetic Field (PEMF) Device) and active drug (Bupivacaine Hydrochloride or Ropivacaine HCl).
Active PEMF + Sham PIB
OTHERParticipants will receive an active device (Pulsed Electromagnetic Field (PEMF) Device) and placebo drug.
Sham PEMF + Treatment PIB
OTHERParticipants will receive a placebo device and active drug (Bupivacaine Hydrochloride or Ropivacaine HCl).
Sham PEMF + Sham PIB
OTHERParticipants will receive placebo drug and placebo device.
Interventions
For active drug, 0.25% marcaine, will be used.
For sham drug, 0.9% saline, will be used.
The pulsed electromagnetic field signal will consist of a 2-m sec burst of 27.12 megahertz (MHz) radiofrequency sinusoidal waves repeating at 2 bursts/second.
Sham devices will appear identical to and will be used in exactly the same manner as active devices but will produce no electromagnetic field.
For active drug, 0.25% naropin, will be used.
Eligibility Criteria
You may qualify if:
- Subjects must be female
- Subjects must be 18 years or older
- Subjects must be undergoing unilateral or bilateral mastectomy with tissue expander reconstruction
You may not qualify if:
- Allergy to all narcotic medications
- Intake of any chronic opioids or pain medications preoperatively for a chronic condition or chronic use.

Limitations and Caveats
Due to drug shortage, Ropivacaine was used in place of Bupivacaine in 1 participant. Bupivacaine and Ropivacaine are FDA-approved local anesthetics currently used in pectoral interfascial blocks for breast surgery patients. Bupivacaine and Ropivacaine are both long-acting local anesthetics with a similar mechanism of action.
