I want to get some books on the NICU to be reading before I start in a few weeks. I am looking into getting the Handbook of Neonatal Intensive Care. I have read a lot about it and people recommended it. The only issue is, I don't have much money and I also have to buy a completely different warddrobe since our hospital has unit-specific colors. I found the 6th edition for much cheaper than the 7th. Does anyone know how different these books are? There are 4 years in between them, so I don't want to buy the 6th edition to save money, if it's only going to give me a bunch of outdated information and advice.
