This study aimed to compare in vitro two syringe changeover techniques to determine which was better at minimising variations in norepinephrine (NE) delivery: the manual quick-change or automated technique. NE concentration was measured continuously using a UV spectrophotometer, and infusion flow rate was monitored by an infusion pump tester. ⋯ The temporary increase in NE mass flow rate was significantly higher with manual relays than with automated ones. The automated relay offered a better control of the amounts of NE administered than the quick-change technique.
