Multimodal Opioid-Free Anesthesia in RIRS
Multimodal Opioid-Free Anesthesia in RIRS: A Comparison of Dexmedetomidine-Ketamine Combination Versus Conventional Opioid-Based Protocols
The goal of this clinical trial is to evaluate whether a dexmedetomidine-ketamine based opioid-free anesthesia (OFA) protocol can provide effective analgesia compared to conventional fentanyl-based anesthesia in adult patients undergoing elective retrograde intrarenal surgery (RIRS). The main questions it aims to answer are:
Does opioid-free anesthesia reduce postoperative opioid consumption compared to fentanyl-based anesthesia? Does opioid-free anesthesia result in lower postoperative pain scores?
Researchers will compare the dexmedetomidine-ketamine group to the fentanyl-based anesthesia group to see if opioid-free anesthesia reduces opioid requirements and improves recovery quality.
Participants will receive either a dexmedetomidine-ketamine based OFA protocol or conventional fentanyl-based anesthesia during surgery and will be monitored for pain, opioid consumption, and recovery outcomes postoperatively.

Description détaillée
Opioids have traditionally been the cornerstone of perioperative analgesia; however, opioid-related adverse effects such as respiratory depression, postoperative nausea and vomiting (PONV), opioid-induced hyperalgesia, sedation, and delayed recovery may negatively affect postoperative outcomes. Opioid-free anesthesia (OFA) is a multimodal anesthetic approach that aims to provide adequate analgesia while minimizing or eliminating perioperative opioid exposure.
Dexmedetomidine and ketamine are commonly used components of OFA protocols. Dexmedetomidine provides sedation and analgesia through selective alpha-2 adrenergic receptor agonism without significant respiratory depression, whereas ketamine reduces central sensitization and opioid-induced hyperalgesia through NMDA receptor antagonism. Their combined use may provide synergistic analgesic and hemodynamic effects.
Retrograde intrarenal surgery (RIRS) is a minimally invasive endourological procedure commonly performed for renal stone disease. Rapid postoperative recovery and early discharge are important goals in this patient population. The use of laryngeal mask airway (LMA) may further facilitate smoother airway management and recovery.
This prospective, randomized, single-center, assessor-blinded clinical trial will compare a dexmedetomidine-ketamine based OFA protocol with conventional fentanyl-based anesthesia in adult patients undergoing elective RIRS under LMA. Eligible participants will be randomized in a 1:1 ratio to either the opioid-free anesthesia group or the opioid-based anesthesia group.
The primary outcomes are postoperative pain scores assessed using the Numeric Rating Scale (NRS) and postoperative opioid consumption during the early recovery period. Secondary outcomes include recovery characteristics, intraoperative hemodynamic parameters, quality of LMA removal, intraoperative patient movement, postoperative nausea and vomiting, surgeon satisfaction, and perioperative adverse events.
The investigators hypothesize that the OFA protocol may reduce postoperative opioid requirements and improve recovery quality while maintaining adequate perioperative analgesia and hemodynamic stability.
