Cardiac surgery — opioid-sparing at scale
In coronary bypass patients, tPEMF extended the evidence well beyond plastic surgery.
The study
Work associated with Baylor College of Medicine and the DeBakey VA examined tPEMF in CABG (coronary artery bypass) patients — a high-acuity surgical population where opioid burden and length of stay are major cost drivers, and a very different setting from the original plastic-surgery trial.
Two findings that travel together
The cardiac work produced two results that each have their own page here: a large reduction in morphine-equivalent dose, and a shorter median hospital stay. Seeing both move in a sicker population is what tells you the effect generalizes beyond elective soft-tissue surgery.
Why payers care about this one
Plastic-surgery pain is a quality story; cardiac length-of-stay is a cost story. By reproducing opioid-sparing in CABG and attaching it to a shorter stay, this work converts the SofPulse case from comfort into economics — the language hospitals and payers actually act on.
The study design
Coronary artery bypass patients — a population with a mean age in the 60s, multiple comorbidities, and high baseline opioid sensitivity risk — received tPEMF or standard care following surgery. Primary outcome was morphine-equivalent dosing over the inpatient stay. Secondary outcome was hospital length of stay measured in calendar days. The study setting (Baylor / DeBakey VA) is a high-volume cardiac surgery program with rigorous standard-of-care protocols, making the comparison group a meaningful benchmark rather than an undertreated control.
What this means in practice
For a CABG patient, lower opioid burden means faster return to ambulation (critical for preventing post-surgical DVT and pneumonia), less respiratory depression (critical in a patient with compromised cardiac reserve), and clearer cognition (reducing post-operative delirium risk, which prolongs stays and is associated with long-term cognitive decline). The two-day shorter stay is the downstream expression of all of those mechanisms running simultaneously.
