Episode 37: Single-bolus Injection of Local Anesthetic, With or Without Continuous Infusion, for Interscalene Brachial Plexus Block in the Setting of Multimodal Analgesia

This AI-generated episode of RAPM Focus discusses the May 2024 publication of “Single-bolus Injection of Local Anesthetic, With or Without Continuous Infusion, for Interscalene Brachial Plexus Block in the Setting of Multimodal Analgesia: A Randomized Controlled Unblinded Trial” by Dr. Patrick Rhyner et al.”

For anyone facing shoulder surgery, pain management after the procedure is crucial. In this paper, Rhyner et al. question whether or not a continuous infusion of pain medication through a catheter is better than giving a patient a single injection after having shoulder surgery. The paper discusses a multimodal approach of pain management—dethamexazone, magnesium, acetaminophen, and ketorolac.

In this study, patients undergoing two common shoulder surgeries—shoulder arthroplasty or arthroscopic rotator cuff repair—were divided into two groups, in which one group received a continuous infusion of medication via catheters, or a single dose of pain relief. Results were measured by how much morphine patients needed through a patient-controlled analgesia pump during the first 24 hours after surgery.
