About

Aart Jan W. Teunissen is a clinical researcher specializing in anesthesiology and perioperative medicine, with a focus on optimizing recovery after major urological surgeries. His key research areas include regional anesthesia techniques, multimodal analgesia, and patient-centered outcomes in the immediate postoperative period. Teunissen’s major contribution is demonstrating the efficacy of intrathecal bupivacaine/morphine in enhancing quality of recovery following robot-assisted radical prostatectomy. In his landmark 2019 randomized controlled trial—cited over 60 times—he showed that this neuraxial approach, added to general anesthesia, significantly improves early postoperative comfort, reduces opioid requirements, and accelerates functional recovery. This work has practical implications for enhanced recovery after surgery (ERAS) protocols, offering an evidence-based strategy to mitigate pain and nausea in a vulnerable patient population. Teunissen’s research bridges the gap between clinical anesthesia and patient-reported outcomes, emphasizing measurable improvements in well-being rather than just physiological endpoints. His findings have been influential in shaping perioperative care guidelines for minimally invasive prostate surgery, making him a respected voice in regional anesthesia and urological anesthesiology.
