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.

Condition Intervention
Pain Relief After Forefoot Surgery
Procedure: Ultrasound guided ankle block
Procedure: Medial forefoot block

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomised, Blinded Comparison of an Ultrasound Guided Ankle Block Compared to a Nerve Stimulator Guided Ankle Block for Pain Relief After Forefoot Surgery.

Further study details as provided by Dr. Andrew J Coe, Hull and East Yorkshire Hospitals NHS Trust:

Primary Outcome Measures:
  • Time taken to carry out each local anaesthetic block [ Time Frame: 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:
  • Onset of local anaesthesia [ Time Frame: 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. [ Time Frame: 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.

Arms Assigned Interventions
Active Comparator: Ultrasound guided ankle block
Subjects in this arm will be given an ultrasound guided ankle block prior to foot surgery.
Procedure: Ultrasound guided ankle block
Under ultrasound guidance, block of the tibial nerve, superficial and deep branches of the common peroneal nerve and saphenous nerves will be carried out using 12 mls 0.5% levobupivacaine and 12 mls 0.75% levobupivacaine.
Active Comparator: Medial forefoot block
Subjects in this arm will be given a nerve-stimulator guided forefoot block prior to anaesthesia and forefoot surgery
Procedure: Medial forefoot block
Using peripheral nerve stimulator guidance, the tibial and common peroneal nerves will be blocked ( plus the saphenous nerve ), using a total of 12 mls 0.75% levobupivacaine and 12 mls 0.5% levobupivacaine.
