I think there is not one book that is enough.Every writer has his special readers  from he started a new book.For example,when we prepare to bronchial nerve block,the major of those books is near,but the exact operation is different, maybe is little,but it can decide the last result.
I think the best solution is RE-Reading all related book, from Anatomy, Physiology, Pathophysiology, Pharmoclogy,etc,at last to our professional issues,so we can contact all the related parts about we need know.
Sorry for my weak English.
