BT_PO 1.132 Antiseptics and disinfectants, clinical uses and risks

This is perhaps not one of the most obvious topics to study, but when you think about it, every patient having surgery, and hence being looked after by us, will be exposed to one of these creatures. Probably a good idea to know something about them, especially their hazards….

There is a reasonable section on this topic in both  Katzung Ch50 and Stoelting’s book Ch41 (until recently unavailable on the ANZCA site – but it is there now, yay!)

For some “clean” is a highly overrated concept….
