Dual-chamber patient-controlled pain relief after laparoscopic sleeve gastrectomy

Comparison of Postoperative Recovery Between Dual-channel Pump for Intravenous Patient-controlled Analgesia(IV-PCA) and Conventional Single-channel Pump After Laparoscopic Sleeve Gastrectomy: a Prospective Randomized Controlled Trial

Not applicable Interventional Seoul National University Bundang Hospital · NCT07051109

This test checks whether a dual-chamber IV patient-controlled pump delivering fentanyl plus ketorolac reduces pain and postoperative nausea and vomiting in adults having laparoscopic sleeve gastrectomy.

What this trial studies

This interventional comparison contrasts a multimodal dual-chamber IV-PCA (fentanyl plus ketorolac) with a single-agent fentanyl IV-PCA in postoperative management. Participants are adult females aged 19–65 with ASA class 1–3 undergoing laparoscopic sleeve gastrectomy who request IV-PCA. Key outcomes include opioid consumption, pain scores, incidence and severity of postoperative nausea and vomiting, and patient recovery satisfaction. The trial is conducted at a single center using the dual-chamber device to attempt opioid-sparing multimodal analgesia.

Who should consider this trial

Good fit: Ideal participants are adult females (19–65 years) with morbid obesity scheduled for laparoscopic sleeve gastrectomy, ASA class 1–3, who plan to use IV-PCA after surgery.

Not a fit: Patients with hypersensitivity to fentanyl or ketorolac, significant liver or renal disease, chronic opioid dependence, or other listed contraindications are unlikely to be eligible or to gain benefit.

Why it matters

Potential benefit: If successful, the dual-chamber PCA could reduce opioid use and postoperative nausea and vomiting, improving recovery quality and patient satisfaction after sleeve gastrectomy.

How similar studies have performed: Previous studies of multimodal analgesia combining opioids with NSAIDs have often reduced opioid requirements and sometimes reduced postoperative nausea, but direct evidence for efficacy of a dual-chamber PCA device is limited.
