Plasma catecholamine concentrations—changes after infiltration with local anaesthetic solutions and adrenaline during bat‐ear surgery

Plasma catecholamine concentrations were measured in 12 patients who had bilateral bat‐ear surgery following infiltration of each ear with 2 ml 2% lignocaine with adrenaline 1: 100 000. Venous blood samples were withdrawn before and at set intervals after infiltration. Plasma adrenaline concentration increased from 0.8 pmol/ml to a peak of 2.2 pmol/ml at 2 minutes after infiltration: this is cm increase of 175%. There was no significant change in plasma noradrenaline concentration.
