About

Ho Geol Ryu is a leading anesthesiologist whose research focuses on optimizing perioperative pain management and refining anesthetic techniques, particularly in robotic and thyroid surgeries. His most cited work investigates the paradoxical risk of postoperative hyperalgesia associated with remifentanil, a common opioid used in total intravenous anesthesia (TIVA). In a pivotal 2018 study, Ryu demonstrated that excessive remifentanil during TIVA for robotic thyroid surgery significantly increases the likelihood of postoperative pain, challenging earlier assumptions that TIVA alone protects against this complication. This finding, cited 8 times, has important clinical implications for tailoring anesthetic protocols to improve patient recovery. Beyond this, Ryu’s broader contributions explore the interplay between anesthetic agents and surgical outcomes, aiming to enhance safety and comfort in minimally invasive procedures. His work is highly regarded for its practical relevance, helping anesthesiologists balance effective intraoperative analgesia with the risk of opioid-induced hyperalgesia. With a growing citation impact, Ryu continues to shape evidence-based practices in perioperative medicine, making him a valuable resource for clinicians and researchers seeking to advance pain management in modern surgery.
