Summary Plasma catecholamine concentrations were measured in 19 patients allocated randomly to receive submucous infiltration with 4 ml of either 0.5% lignocaine with adrenaline 1:200 000 or prilocaine 0.5% with octapressin 0.03 iu per ml. Venous blood samples were obtained before and at 2, 5, and 10 minutes following infiltration. Plasma adrenaline increased from 0.35 to 1.72 p mol/ml at 2 minutes infiltration with the former solution whilst there was little change in plasma noradrenaline concentration. No similar peak in adrenaline concentration occurred after infiltration with prilocaine/octapressin solutions but with both solutions there was a small increase in plasma noradrenaline and adrenaline concentrations 10 minutes after infiltration, at the time of surgical stimulation.
