Obturator and Femoral Nerve Block in Patients With Hip Fracture

• Status: Unknown status
• Trial end date: 2017-04-01
• Target enrollment: 0
• Participant gender: All

Summary

A higher number than expected of patients with hip fracture have only insufficient analgesic effect of a femoral nerve block, which is the nerve block commonly used for this group of patients. One of the possible causes of this failure to provide analgesia from a single nerve block could be the that other nerves are involved in transmitting the pain signal. One of the nerves that is believed to give off branches to the hip is the obturator nerve.

With ultrasound it is possible to make a selective proximal nerve block of the obturator nerve.

The aim of this trial is to test the analgesic effect of a femoral nerve block i combination with an obturator nerve block compared to femoral nerve block alone in a randomized and placebo controlled design.
