Continuous versus bolus ibuprofen for pain after laparoscopic surgery

Continuous vs. Bolus Administration of NSAIDs After Laparoscopic Surgery for Multimodal Analgesia: Pilot Randomized Controlled Trial

Phase 4 Interventional Federal Research and Clinical Centre of Intensive Care Medicine and Rehabilitology · NCT07070050

This trial tests whether giving ibuprofen as a continuous infusion instead of intermittent bolus doses reduces pain and opioid use for adults having elective laparoscopic surgery.

What this trial studies

This Phase 4 interventional study compares continuous infusion of ibuprofen with standard bolus injections as part of multimodal analgesia after elective laparoscopic surgery in adults. Eligible patients (>18 years) who undergo general anesthesia and meet safety criteria will receive either a continuous postoperative ibuprofen infusion or intermittent bolus dosing, with pain scores, analgesic consumption, and adverse events recorded. The protocol is aligned with ERAS principles to minimize opioid use while monitoring for NSAID-related side effects such as bleeding, renal dysfunction, or liver enzyme elevations. Enrollment is limited to patients admitted to the participating hospital and requires a RASS score between -2 and +1 on admission.

Who should consider this trial

Good fit: Adults scheduled for elective laparoscopic surgery under general anesthesia who can give informed consent and do not have contraindications to ibuprofen (no allergy, no significant kidney or liver disease, no active GI ulcers, no asthma or coagulopathy, not on anticoagulants or chronic opioids/NSAIDs).

Not a fit: Patients with ibuprofen allergy, active erosive or ulcerative gastrointestinal disease, chronic kidney disease stage ≥3b, marked liver dysfunction, asthma, hereditary coagulopathies, current anticoagulant use, or chronic opioid/NSAID use are excluded and would not be expected to benefit from this protocol.

Why it matters

Potential benefit: If successful, this approach could improve postoperative pain control and reduce opioid requirements after laparoscopic surgery.

How similar studies have performed: Previous studies of continuous perioperative NSAID infusion have produced mixed results, with some showing improved analgesia and opioid-sparing and others finding no clear advantage.
