Summary Sympathetic blockade after stellate ganglion block with bupivacaine was assessed by liquid crystal thermography. The minimum concentration of bupivacaine required for successful block was between 325 and 406 μmol/litre. Further study of bupivacaine in a solution that contained potassium 5 mmol/litre showed that this reduced the minimum concentration of bupivacaine required for successful block to between 81 and 162 μmol/litre. We conclude that potassium has a major effect on the minimum concentration of bupivacaine required for sympathetic blockade.
