About

Donn Marciniak is a regional anesthesiologist and clinical researcher whose work centers on the intersection of pain management and cardiothoracic surgery, with a particular focus on fascial plane nerve blocks as alternatives to opioid-based analgesia. His most significant contributions lie in evaluating chest wall regional anesthesia techniques — specifically serratus anterior and pectoralis plane blocks — in the context of minimally invasive and robotically assisted cardiac and thoracic procedures. Marciniak's landmark 2023 randomized clinical trial examining these blocks for robotic mitral valve repair has already garnered 33 citations, reflecting its rapid influence on perioperative pain management practices. His follow-up 2024 trial explored the added benefit of liposomal bupivacaine to extend the duration of analgesia in minimally invasive thoracic surgery, addressing a critical clinical challenge: postoperative pain that can compromise pulmonary recovery. His engagement with the broader research community, including published correspondence on simplifying regional techniques for anterior thoracotomy, further demonstrates his commitment to translating evidence into accessible clinical practice. Marciniak's work is shaping a shift toward opioid-sparing, procedure-specific anesthesia strategies in cardiac and thoracic surgery.
