How intravenous nitroglycerine transit time from bag-to-bloodstream can be affected by infusion technique: a simulation study.

Despite limitations, this study outlines the importance of cannula type, infusion accessories and carrier lines. Larger cannulae and greater priming volumes substantially delay drug delivery, whereas carrier lines/drive lines substantially accelerate drug delivery. Our study also shows how patients could be exposed to clinical delays, as well as incorrect presumptions about drug dosage. Guidelines, and education efforts, should highlight the clinical importance of factors that affect bag-to-bloodstream time.
