Ognjen Visnjevac

Ognjen Visnjevac is an Assistant Clinical Professor (Adjunct) in the Department of Anesthesia at McMaster University. With a focus on interventional pain management and anesthesiology, his work has significantly contributed to refining techniques for chronic pain treatment, including radiofrequency ablation and spinal cord stimulation.

His research spans cellular and molecular mechanisms of analgesic agents like ketamine and naltrexone, as well as preoperative risk assessment using biomarkers such as serum potassium. He has also explored the limitations of traditional systems like ASA classification in predicting postoperative outcomes.

Recent publications highlight 2024 chapters on vertebral anatomy and future medical technology, alongside 2022-2021 studies on radiofrequency lesion safety, sacroiliac joint pain, and fibromyalgia treatment. His work integrates clinical research, neurosurgical data, and pharmacological insights.

Dr. Visnjevac's scholarly activity has been widely disseminated, with multiple systematic reviews and clinical trials referenced in guidelines, social media, and policy documents. His work bridges translational research and practical applications in pain management and anesthesia.
