Using dexmedetomidine and fentanyl for pain control after major abdominal surgery

Effectiveness of Two-channel Intravenous Patient-controlled Analgesia With Dexmedetomidine on Postoperative Opioid Consumption After Major Laparoscopic Abdominal Surgery

Not applicable Interventional Korea University Guro Hospital · NCT05672225

This study is testing a new pain management method using a special device that gives patients dexmedetomidine and fentanyl after major abdominal surgery to see if it helps control pain better while using less opioids.

What this trial studies

This clinical trial investigates the effectiveness of a dual-channel intravenous patient-controlled analgesia (IV-PCA) device that administers dexmedetomidine and fentanyl separately for pain management following laparoscopic major abdominal surgery. The study compares opioid consumption and evaluates pain intensity, postoperative nausea/vomiting, and delirium in patients receiving this novel analgesic approach. By utilizing a new IV-PCA device, the trial aims to enhance pain control while minimizing opioid use and associated side effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 and older scheduled for laparoscopic major abdominal surgeries such as gastrectomy, hepatectomy, colectomy, or pancreatectomy.

Not a fit: Patients with severe cardiovascular disorders, significant liver or renal dysfunction, or contraindications to dexmedetomidine will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and reduced opioid consumption for patients undergoing major abdominal surgery.

How similar studies have performed: While the use of dexmedetomidine in postoperative settings has been reported, this specific dual-channel IV-PCA approach is novel and has not been extensively tested in similar studies.
