Plasma catecholamine concentration and dopamine-beta-hydroxylase activity during haemodialysis with acetate or bicarbonate at different sodium concentrations in hypotensive patients.

Plasma catecholamines (noradrenaline, adrenaline, dopamine) and dopamine-beta-hydroxylase were investigated in hypotensive haemodialysis patients treated with different sodium dialysate concentrations in acetate or bicarbonate fluids. The present results suggest that most physiological reactions could be obtained in patients treated with equimolar sodium concentration in blood and dialysis fluids in both kinds of acetate and bicarbonate.
