A 1:1 mixture of 0.5% L-bupivacaine and 1% lidocaine will be infiltrated around the operative site by the operating surgeon. After 5 min, adequacy of anaesthesia will be tested by application of a painful stimulus and additional LA infiltration administered as required. Maximum dose limits of 2 mg/kg for bupivacaine and 3 mg/kg for lidocaine will be observed, recognising the effects are additive.
