Ultrasound Guided Ankle Block Versus Medial Forefoot Block for Forefoot Surgery

Not Applicable

Completed

• Conditions: Pain Relief After Forefoot Surgery
• Interventions: Procedure: Medial forefoot block; Procedure: Ultrasound guided ankle block

• Registration Number: NCT01386320
• Lead Sponsor: Hull University Teaching Hospitals NHS Trust

Brief Summary

Forefoot surgery includes bunion surgery and similar reconstructive bone cutting surgery and is very painful. Local anaesthetic nerve blocks have been used for many years to help alleviate pain following this surgery. The present study aims to compare a new ultrasound guided nerve block to a well established nerve stimulator guided technique. Comparisons will include time taken to carry out the block, speed of onset of numbness and duration and quality of pain relief after surgery.

Arm && Interventions

Group	Intervention	Description
Medial forefoot block	Medial forefoot block	Subjects in this arm will be given a nerve-stimulator guided forefoot block prior to anaesthesia and forefoot surgery
Ultrasound guided ankle block	Ultrasound guided ankle block	Subjects in this arm will be given an ultrasound guided ankle block prior to foot surgery.

Primary Outcome Measures

Name	Time	Method
Time taken to carry out each local anaesthetic block	Over forty five minutes from the start of the study.	Time taken between opening sterile packs and completion of local anaesthetic block is measured by a blind observer.

Secondary Outcome Measures

Name	Time	Method
Onset of local anaesthesia	Over thirty minutes from completion of the local anaesthetic block.	Following administration of the local block, development of anaesthesia will be measured looking at cold and pin-prick sensation by a blind observer.
Duration of pain relief following local anaesthetic block.	Over 24 hours following surgery.	Pain relief will be assessed over 24 hours following surgery, to assess its duration and quality, by a blind observer.
