Scientific title
Study objectivesDoes pre-operative administration of ankle block (pre-emptive analgesia) provide better post-operative pain control as compared to post-operative ankle block in patients undergoing bony forefoot surgery under a general anaesthetic?
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSurgery: Forefoot
InterventionPatients meeting the inclusion criteria would be randomised to one of the two groups using a sealed envelope technique.

One group of patients would receive an ankle block using 20ml of 0.25% bupivacaine after they are anaesthetised using a general anaesthetic, 10 minutes before the skin incision. The second group of patients would be administered an ankle block using the same method at the time of wound closure.The patient would be blinded to the type of ankle block.

All the patients would be asked to score their post-operative pain at 4, 8 and 24 hours. The pain would be assessed using linear visual analogue scale. The person assessing the post-operative pain would also be blinded to the type of analgesia. Additional analgesia would be administered on patient's request. This would include 60mg of codeine and 1gm paracetamol. The patients would be asked to note the pain score whenever an analgesic is administered. The time of onset of pain and the frequency of analgesics required would be noted.

Added 27 August 2008: trial stopped due to poor recruitment.
