Robert Bojar's "Perioperative Care in Cardiac Surgery" should be given to every new person that comes into CVICU in my opinion. I had a CV Surgeon give it to me years ago and Ive convinced about 25 people in my unit to buy it, as well as the hospital to buy it for new employees/new grads. Its the best book Ive read. During orientation I try to get my orientees to udersand three basic receptors....Alpha-1, Beta-1 and Beta-2. Instead of memorizing up and down arrows in a book or note cards, it helps them learn it easier. If you can understand that a Beta-2 receptor causes peripheral and bronchodialation and that Alpha adrenergic drugs cause arterial constriction, and that Beta-- causes and increase in HR and contractility, you can figure out that Dobutrex, Epi, Dopamine, Neo, ect...........do X, Y, and Z because of the receptors they stimulate. Also, go to PACEP.org and register (its free). Do all the programs for Swans. You can train a monkey to learn paperwork, how to shoot numbers, how to titrate drips and such, however to understand the science is something that a majority of the people you work with dont understand, Im willing to be. Good luck.
