Medial Forefoot Block for Analgesia After Foot Surgery

Not Applicable

Completed

• Conditions: Hallux Valgus
• Interventions: Procedure: Landmark guided ankle block.; Procedure: PNS guided block.

• Registration Number: NCT01445249
• 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 are used to provide pain relief after this work. The purpose of this study is to compare two techniques: one using anatomical landmarks alone to guide local anaesthetic infiltration, the other using peripheral nerve stimulation to guide local anaesthetic infiltration (termed medial forefoot block). The two techniques will be compared for reliability of postoperative analgesia.

Arm && Interventions

Group	Intervention	Description
Landmark guided ankle block	Landmark guided ankle block.	This group will receive a landmark guided ankle block.
This group will be given a PNS guided ankle block	PNS guided block.	Peripheral nerve stimulation will be used in this group to guide local anaesthetic infiltration. The technique is termed medial forefoot block.

Primary Outcome Measures

Name	Time	Method
Efficacy of local anaesthetic block.	Over ninety minutes from the start of the study.	The number of patients in each study arm with altered sensation to cold and pin prick, together with no requirement for opiate analgesia, following surgery was recorded.

Secondary Outcome Measures

Name	Time	Method
Intravenous opiate usage following surgery	24 hours following surgery	The usage of intravenous morphine, delivered by a ptient controlled analgesia system, in each group was recorded.
