Early and Late Effects of Nefopam in Multimodal Analgesia After Total Hip Arthroplasty (NEFARTHRO)

Phase 3
Not yet recruiting
Conditions
Total Hip Arthroplasty
Interventions
Drug: NaCl 0.9%
Registration Number
NCT06349798
Lead Sponsor
University Hospital, Tours
Brief Summary

NEFARTHRO is a multicentric randomized controlled trial comparing the effects of discontinuous infusions of nefopam (bolus) versus continuous infusion of intravenous nefopam (via an infusion pump) versus placebo on the opioid-request during the first 24 hours following a Total Hip arthroplasty, as part of multimodal analgesia including at least paracetamol and a Non-Steroidal Anti-Inflammatory Drug (NSAID).

The primary endpoint is cumulative morphine consumption for the first postoperative 24 hours, expressed in mg of iv equivalent morphine, including titration in the Post Anesthesia Care Unit (PACU).

Patients will be followed during 6 months.

Time to abandon canes/crutches.At Hour 24, at Day 5 or at discharge, whichever came first and at Month 6
Chronic pain at 6 months (at rest and walking) using a standardized phone questionnaire.At Month 6
Maximum self-assessed pain using the Numeric Rating Scale ranging from 0 (no pain) to 10 (maximum pain) at rest in the PACU, at rest and on walking between PACU discharge and Hour 24, at Hour 24, and at hospital discharge.at PACU, between PACU discharge and Hour 24, at Hour 24 and at Day 5 of hospital discharge
Time to return to walking.At Hour 24, at Day 5 or at discharge, whichever came first and at Month 6
Time to climb stairs.At Hour 24, at Day 5 or at discharge, whichever came first and at Month 6
Financial impact of spreading the recommended strategy following the results of the clinical study, estimated per year and over a 5-year period, from the point of view of the French Health Insurance and from the hospital perspective.5 years

These financial impacts will be estimated using budget impact models.
