[Plasma-catecholamines under electrostimulation and neurolept anaesthesia for retina and vitreous body operations (author's transl)].
We determined in two groups of patients with normal circulation and metabolism during operations on the retina and vitreous body the concentration of plasma catecholamines. The intensity of stress was compared between electrostimulation anaesthesia and neuroleptanaesthesia. Venous blood was sampled 1) before premedication, 2) 30' after premedication, 3) at the start of surgery, 4) 45' after the start of surgery, 5) 30' after extubation. Plasma catecholamines (adrenaline and noradrenaline) were determined using a modified trihydroxyindol-spectrofluoremetric method (combined "Batch-technique"). There was no relevant difference between the two techniques of anaesthesia when using the concentrations of plasmacatecholamines as an indicator of stress resulting from operation and anaesthesia.
