Drug administration is one of the main sources of errors in pediatric intensive care units (PICUs). An available guide for intravenous drug administration might be useful. The aim of this article is to present the methodology and results for the development of a guide for intravenous drug administration in a PICU. A total of 116 drugs were included. Standard concentrations, diluents, technique for reconstitution and dilution, stability, rate of administration, and relevant observations were defined for each drug according to a review of the most commonly used literature resources. The main unique feature of this article is that it includes standard concentrations for each drug.
