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

Condition(s) studied

Investigational drug(s) / intervention(s)

Nefopam: 20 mg nefopam in 50 ml of saline, during a 30 min infusion, before end of procedure, then a similer bolus every 4 h for 24 h (6 injections in total) + continuous intravenous infusion of placebo (2 mL/h saline)

Nefopam: 20 mg nefopam in 50 ml of saline, during a 30 min infusion, before end of procedure, then a bolus of placebo every 4 h for 24 h (6 injections in total) + continuous infusion of 100 mg nefopam over 24 h (in 48 mL saline, 2 mL/h)

NaCl 0.9%: 50 ml of saline, during a 30 min infusion, before end of procedure, followed by a bolus of placebo every 4 hours for 24 hours (6 injections in all) + continuous infusion of placebo (2 mL/h of physiological saline)

Study 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.

Eligibility

Primary outcome measure(s)

• Cumulative morphine consumption from the end of surgery (Day 0 - Hour 0) to the first 24 hours after surgery, expressed in mg of intravenous morphine (including titration in the Post-Anesthesia care Unit PACU). — between Day 0 - Hour 0 and Hour 24 post surgery
