title: Plasma catecholamine levels during functional endoscopic sinus surgery.
abstract: Plasma adrenaline and noradrenaline concentrations were measured in 10 consecutive patients during functional endoscopic sinus surgery (FESS). Surgery was preceded by nasal packing with 5 ml 2% cocaine solution, followed by infiltration with 1:80,000 adrenaline and 2% lignocaine. All patients showed a marked rise in plasma adrenaline concentration within 4 min of commencing infiltration, which was not related to the patient's sex, age, weight, the total amount injected, nor the amount injected into the nose. Surgeons should be aware of this marked, but unpredictable, systemic absorption of locally infiltrated vasoconstrictors. Pulse and ECG monitoring should be considered mandatory for such procedures, even when surgery is performed under local anaesthesia.
