Shamrock - Ultrasound/MR Image Fusion Guided Lumbar Plexus Block

• Status: Completed
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 22 (actual)
• Sponsor: University of Aarhus · Academic / Other
• Sex: All
• Age: 18 Years – 85 Years
• Healthy volunteers: Accepted

Summary

The main objective is to complete a double-blinded randomized controlled crossover trial of lumbar plexus block with the Shamrock technique guided by ultrasound (US)/magnetic resonance imaging (MRI) image fusion vs. the Shamrock technique guided by ultrasound in healthy volunteers. The investigators will assess block procedure-related parameters, anatomical spread of local anesthetic, and motor and sensory effects.

Conditions

• Hip Fractures
• Anesthesia, Local
• Pain, Postoperative

Interventions

Type	Name	Description
PROCEDURE	Ultrasound/MR image fusion guided lumbar plexus block (Shamrock)
PROCEDURE	Ultrasound guided lumbar plexus block (Shamrock)
DRUG	Lidocaine-epinephrine added gadoterate meglumine	Perineural injection of 20 ml 2% lidocaine with 0.0005% epinephrine added 1 ml of gadoterate meglumine (0.13 ml) and sodium chloride (NaCl, 0.87 ml). The 1 ml of gadoterate meglumine-NaCl is added to the local anesthetic prior to the perineural injection in order to enhance visualization of the local anesthetic on MRI scanning after the intervention.
