Intravenous tubing containing burettes can be safely changed at 72 hour intervals.

摘要: No studies testing the safety of changing intravenous systems containing in-line burettes at 72 hours in an intensive care setting have been performed. Patients entering a medical or surgical unit were alternatively assigned to any line with burette changed either 48 hour (105 patients) (65 intervals. Daily quantitative cultures 2 ml aliquot fluid obtained. Contaminated was detected 60 1181 (5.0%, 95% confidence interval, 3.7% 6.3%) samples from intervals, and 40 901 (4.4%, 3.0% 5.8%) interval burettes. Significant bacterial contamination fluid, defined as ten more colonies per milliliter, occurred only seven (0.6%) patients group compared three (0.3%) group. None contaminated fluids associated primary bacteremia. Change 72-hour intervals is safe should result substantial cost savings hospitals.
