Intravenous administration sets were changed at varying time intervals between every 24 h and 120 h in 387 patients. The rates of intraluminal contamination of the cannulae and of local inflammation were measured in relation to the time interval between changing sets. There was no correlation between phlebitis and intraluminal contamination, but a significant association was found between phlebitis and fever, infusion of potassium at greater than 10 mmol l-1, Venflon type 140 and infusion of blood or intralipid. No correlation was found between septicaemia and intraluminal contamination of the infusion systems. Contamination of cannulae increased slightly with time, but this was not statistically significant. We conclude that there will be no clinical benefit by daily changing of administration sets, compared with changing up to every fifth day.
