The effect of local anaesthetic type on injection-related pain levels intra and post operatively
In patients undergoing bilateral hallux blocks for partial nail avulsion, is mepivacaine a more effective local anaesthetic than lignocaine for reducing injection-related pain levels.

Summary
A double blind trial designed to assess the pain associated with the injection of lignocaine (Xylocaine) and mepivacaine (Scandonest) two local anaesthetics commonly used in podiatric practice. So, is mepiviacaine a less painful anaesthetic to be injected into a toe than lignocaine. Subjects will be selected from the University of Newcastle Podiatry Clinic, the subjects have been selected would require nail surgery of both big toes. The practitioner and the subject will be blinded to which anaesthetic has been used in each of the toes. After each injection the subject will be asked to complete a visual analog pain scale.

Interventions
A total of 2ml of 3% mepivacaine plain will be injected in the hallux (with 5ml syringe and a .25 gauge, 25mm in length) prior to the partial nail avulsion procedure. The subject will receive 1ml of mepivacaine into the soft tissue on the lateral (1st injection) and medial (2nd injection) aspects of the proximal phalanx. The partial nail avulsion will only be performed once the anaesthetic has taken effect. If anaesthesia has not been achieved then a top up injection will be performed. The allocation of which hallux, right or left that receives lignocaine or mepivacaine will be randomised. Immediately after the injections into the medal and lateral aspects of the toe the subject will complete a visual analogue pain scale, if further injections are required then the visual analogue scale will be completed after the first (lateral aspect) and second injection (medial aspect). Crossover will be achieved by the randomly selected hallux will receive lignocaine or mepivacaine and the opposite hallux will be injected immediately after the subject has completed the visual analogue scale.
