Continuous Adductor Canal Block With a New Catheter - Primary Placement and Secondary Repositioning

• Status: Completed
• Trial end date: 2016-03-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a single center, randomized, blinded trial in healthy volunteers. The volunteers will receive bilateral placement of the new catheter corresponding to the adductor canal. Each volunteer will have a catheter placed in the adductor canal in both legs. The catheters are randomized to be placed either in the long-axis or short-axis plane of the adductor canal. Both catheters will be injected with local analgesics (LA). Allocation will be blinded to the volunteer and the investigator assessing sensory function. The volunteers will be sent home with the catheter in situ and return the following day. Injection with LA is repeated and sensory function is tested again. Furthermore catheter position is determined with ultrasound during injection. If sensory function is not affected by injection of LA then the catheter is visualized with ultrasound and repositioned followed by a second injection of LA and subsequent assessment of sensory function
