Although I am waiting for an interview, I have two books I like that aren't too dry. I can assimilate what I have learned almost everday at work, and the books have pictures!!
1. Basics of Anesthesia, Stoelting, R. and Miller, R., 4th ed., 2000
2. Hemodynamic Monitoring, Darovic, G., 3rd ed., 2002
B of A is a very broad book that succinctly presents pertinent information about anesthesia. Not intended as a reference manual, so the information presented is not quite as in-depth as a textbook would be. It has a decent chapter on opoids--which is a great review. It also has good review of autonomic nervous system and basic pharmocologic principles.
Hemodynamics is deep, and I use it as a reference but provides alot of useful info. i.e. those unexpected or unusual cases. The book is designed more for the ACNP or PA or RN at the bedside, but it is a very interesting book if you feel like synthesizing some of your "experience"knowledge with a text.
Just my two cents--and believe me, on the right night, both of these books can induce a deep-sleep, but when I am motivated, the books have filled in alot of gaps in my own knowledge base. I hope this will later aid me in practice. Good luck in our quest.
