In the era of fast-tracked surgery and same-day discharge, anesthesiologists are looking for strategies to optimize recovery without compromising safety or pain control. A long-standing debate centers around whether low-dose bupivacaine or mepivacaine is the better spinal agent to promote early ambulation after total knee arthroplasty. In this episode of RAPM Focus, RAPM Editor-in-Chief, Brian Sites, MD, explores this debate with Clinton Pillow, MD, following the May 2025 publication of “Mepivacaine versus bupivacaine spinal anesthesia for return of motor function following total knee arthroplasty: a randomized controlled trial.”

This episode explores a topic faced by every anesthesiologist that manages joint replacements, especially total knee arthroplasty, has grappled with—what is the ideal spinal anesthetic when time is money and same-day discharge is the goal?

Dr. Pillow is an assistant professor in the department of anesthesiology and perioperative medicine at the Medical University of South Carolina.

In this episode of RAPM Focus, Editor-in-Chief Brian Sites, MD, discusses the use of buprenorphine for acute pain management with Thomas Hickey, MD, MS, following the February 2025 publication of “Buprenorphine versus full agonist opioids for acute postoperative pain management: a systematic review and meta-analysis of randomized controlled trials.”

Dr. Hickey is full-time staff at the West Haven VA where he is medical director of preoperative evaluation and the PACU, and site director for the anesthesiology residency. Within the VA, he is chairman of the VA New England Healthcare System committee on preoperative evaluation and ERAS, co-chair of the VA’s national pain/opioid consortium for research workgroup on perioperative management of medications for opioid use disorder, and a member of the National Anesthesia Program Acute Pain Management Committee. He is board certified in both anesthesiology and addiction medicine. His research interests focus on the overlap between addiction medicine and acute pain management, particularly on the use of buprenorphine for acute pain management. He and his wife are kept busy by their three kids and all their activities.

In this episode of RAPM Focus, Editor-in-Chief Brian Sites, MD, speaks with RAPM Editor Ryan D’Souza, MD, and Nasir Hussain, MD, following the October 2024 publication of “Hidden Influence? Unmasking Conflicts of Interest from Randomized Clinical Trials on Spinal Cord Stimulation for Chronic Pain.”

Let’s set the stage first. Spinal cord stimulation, or SCS, is a therapy that involves implanting a device that sends electrical signals to the spinal cord, aiming to disrupt pain signals before they reach the brain. It’s a rapidly evolving field with a lot of promise, but it also attracts substantial investment from medical device companies.

Now, when we talk about conflicts of interest, or COIs, we’re referring to situations where a researcher’s personal interests, particularly financial ones, have the potential to cloud their professional judgment and influence the outcomes of their research. Think of it this way: if a researcher is financially tied to a company that makes a specific SCS device, might they be more inclined to see their research results in a favorable light? That’s the concern.

Dr. Ryan D’Souza is an associate professor and pain medicine physician at Mayo Clinic. He is the Director of Neuromodulation, and Director of the Inpatient Pain Service. He serves on the Board of Directors of the North American Neuromodulation Society and also serves in leadership roles for ASRA Pain Medicine. Dr. D’Souza has authored over 150 peer-reviewed publications and serves on several editorial boards.

Dr. Nasir Hussain is a pain medicine physician and anesthesiologist at the Ohio State University. He is an assistant professor, associate program director for the anesthesiology residency, and assistant program director of the chronic pain fellowship. Dr. Hussain has authored over 110 peer-reviewed publications in leading journals in the field, and has presented his work nationally at several conferences.
