Bupivacaine 0.375% 20-30mls (depending patients weight)

After patients have given their consent to being in the study they will be randomised
Patients will be asked to record their level of pain by
1. using a visual analogue scale (VAS) on paper

VAS = visual scale 100mm’s in length with no pain at the left hand side and worst pain ever experienced at the right hand side. Patients will be asked subjectively to place a mark on the line where they feel there level of pain is at there pre-operative assessment, and then 4, 8, 12, 24, 48 hours post-operation.
