The stability of four catecholamines in 5% glucose infusions.

The stability of adrenaline, noradrenaline, dopamine and dobutamine in 5% glucose infusion minibags stored at 5 degrees C was determined. Results indicated that noradrenaline (16 and 40 mg/l) and dobutamine (1 and 5 g/l) were relatively stable with t/95% values in excess of 30 days. Adrenaline and dopamine were less stable. The t/95% values were approximately 20 and 14 days respectively.
