Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) undergoing scheduled laparoscopic abdominal surgery expected to last at least 2 hours and who are enrolled in the social security system with consent.

Probably not a fit

Patients with severe allergies to study medications, certain drug interactions, or conditions excluded by the criteria may not benefit from this approach.

What this trial studies

This interventional study compares tramadol and morphine for postoperative pain control in adults undergoing laparoscopic abdominal surgery, within a multimodal analgesia framework. It aims to reflect current clinical practices and assess tolerability and safety profiles. The trial examines induction and maintenance anesthesia, plus multimodal analgesia strategies, to determine if tramadol can match morphine in effectiveness while potentially differing in side effects. Participants will be adults aged 18 or older with planned procedures lasting at least two hours and who are enrolled through social security systems, with informed consent required. Exclusion criteria include allergies to common analgesics, contraindications to study drugs, chronic certain enzyme inhibitors, high-risk surgery, psychiatric conditions, and other factors that could confound results.

Why it matters

Potential benefit: If successful, tramadol could offer a safer or equally effective alternative to morphine within multimodal regimens, potentially reducing opioid-related risks.

How similar studies have gone: Prior research supports multimodal analgesia approaches, but direct head-to-head comparisons of tramadol and morphine in this specific surgical context are limited and findings may be variable.
