NCT03376178

Brief Summary

Multiorifice catheters have been shown to provide superior analgesia and significantly reduce local anesthetic consumption compared with end-hole catheters in epidural studies. This prospective, blinded, randomized study tested the hypothesis that, in continuous femoral nerve block (CFNB) under ultrasound guidance, multiorifice catheter would reduce local anesthetic consumption at 24h compared with end-hole catheter.

Masking Details
All investigators, patients, and other clinical staff were blinded to the treatment group. The investigator in charge of the patient was unaware of patient allocation. He did not perform the block or open the sealed and opaque envelope, but followed the patient in the ward. An opaque skin dressing was used in order to blind the type of catheter used. End-hole catheter Vygon is white and stiff whereas six-hole catheter contiplex is yellow and flexible.
Purpose
TREATMENT
Intervention Model
PARALLEL
Model Details: Eighty adult patients (aged ≥18 years) scheduled to undergo primary total knee arthroplasty under a combination of CFNB, sciatic nerve block and general anesthesia were randomized to CFNB using either a 3-pair micro-hole (Contiplex, BRAUN®, 20G - 400 mm) or an end-hole (Silverstim VYGON®, 20G - 500 mm) catheter. Once the femoral catheter was sited, a bolus of 20 mL lidocaine 1% was injected. An electronic pump then delivered an automated 5 mL bolus of ropivacaine 0.2% hourly, with 10 mL self-administered patient controlled analgesia boluses.
