简要总结
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.

研究组 & 干预措施
Ultrasound guided ankle block
Subjects in this arm will be given an ultrasound guided ankle block prior to foot surgery.
干预措施: Ultrasound guided ankle block (Procedure)
Medial forefoot block
Subjects in this arm will be given a nerve-stimulator guided forefoot block prior to anaesthesia and forefoot surgery
干预措施: Medial forefoot block (Procedure)
结局指标
主要结局
Time taken to carry out each local anaesthetic block
时间窗: 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.
次要结局
- Onset of local anaesthesia(Over thirty minutes from completion of the local anaesthetic block.)
- Duration of pain relief following local anaesthetic block.(Over 24 hours following surgery.)
