This is a question new student often ask. Unfortunately, it isn't that simple.
Each anesthetic is unique. To plan for it you need to factor in the patient's coexisting disease, medications, reason for surgery, surgical approach and even individual surgeon.
You will be making decisions about type of anesthesia, drugs, doses, interaction of patient's meds with anesthesia drugs, monitoring, positioning, complications (recognition and treatment), blood loss, fluids and post op pain needs.
These decisions are based on your knowledge of the patient, along with your understanding of physiology, pharmacology, anesthesia principles, and the interaction of them all together.
So you can see, you will not find all of this in one book. Adequate planning requires a synthesis of many sources. At first you will be looking up EVERYTHING. As you progress, you internalize the knowledge, the routine things come to you more naturally, and you only have to look up the unusual things.
Having said all this, there are a couple books that might help. Anesthesiologist's manual of surgical procedures by Jaffe. This one is particularly helpful if you are lost about what the surgery is going to be like. But please only use it in that context. I could always tell when students used Jaffe as their only source- they could tell me how to do the surgery, but left out many important aspects of the ANESTHESIA. It irritated me so much, I almost hesitate to recommend it-hehe.
The other is Essence of anesthesia practice by Roizen. It has one page summaries of the anesthesia implications of surgeries and coexisting diseases.
My favorite book is Stoelting's Anesthesia and coexisting disease. I still use it when I am confronted with the "I learned about it in school, but haven't seen it since" situation. But it also has great sections on more common diseases as well. Don't let the name fool you, it is organized by how you approach each aspect of the anesthetic (what do you give for preop, is it OK to do a regional, what are appropriate monitors, etc.)
But the truth is, any and all of your anesthesia texts are your best sources for planning. It is brutal at first, but it does get easier with experience. Congrats to you, and good luck in school!
