Can I recommend two books that may be interesting background reading for Nurses and clinical trainers, in particular. "A Pocketbook for Safer IV Therapy" edited by Martin Pickstone; 1999; ISBN:0-948672-32-3 and "Intravenous Therapy in Nursing Practice" Dougherty and Lamb; 1999; ISBN:0-443-05983-7.
The books include the relevent references to issues such as the delivery of specific drugs and problems encountered with IV therapy, including selection of devices and equipment maintenance considerations. They are probably on Nurses suggested reading lists anyway. I am not a clinical trainer, I have no association with the authors of these publications but I have read these books myself and found that I understand many of the, practical, clinical aspects much better than I did before. There may be more up to date, revised editions, of course.
