I used this in EMT class, and I still go back to it often as a reference. There aren't many books written for the EMT-B level, and they tend to follow the same format: EMS procedures and a big lump of basic physio at the beginning, followed by many chapters on different emergencies, and ending with special topics like advanced airways and ALS assist. There are always a few scenarios sprinkled throughout each chapter, and usually some advice from veteran EMT's and paramedics. I'm partial to Brady's "Emergency Care" on these points: the anecdotes are candid, and it includes pertinent information like considerations for dealing with foreign cultures (example: touching a child's head can be deemed either respectful or insulting, depending on the family's background). In contrast, I've found "The Orange Book" frustratingly bureaucratic: for instance, it categorizes course objectives as "affective", "cognitive", and "psychomotor," a distinction which is unhelpful, even meaningless to a practicing EMT. The authors include frequent reminders to follow local protocols, which lets them avoid giving actual instructions.
The most frustrating characteristic of this book is its redundancy. A&P is covered in chapter 4 ("The Human Body"), and then repeated piecemeal throughout the book. For instance, the chapter on respiratory emergencies repeats the same information given in chapter 4, even repeating the same diagrams. Very little detail is added with each repetition. Likewise, each chapter discusses the full patient assessment, including parts which aren't relevant. For instance, the section on sexual assault says to "make airway care a high priority." Airway care is ALWAYS a high priority, and there is no particular reason why airway care should be different (or even particularly relevant) when dealing with sexual assault. It seems as though the authors assume the reader has forgotten everything mentioned in the previous chapters, and the result is a book overstuffed with redundant information.
The book is written by the academy of orthopedic surgeons, and it shows. The section on trauma care is quite thorough, discussing many different types of fractures and dislocations in more detail than the average EMT is likely to know. That said, trauma care is generally straightforward: bandage what's bleeding, splint what needs splinting, and get to the hospital. Medical (non-traumatic) emergencies are generally trickier, and this is where the book falls short. Congestive heart failure-- a serious condition which accounts for many of our calls-- receives only a single page. Discussion of syncope (perhaps my most frequent call) is similarly sparse. Many of our patients have some form of cancer, and the index lists only a single mention of the disease.
Lastly, a plea for better organization. Like most books, this one categorizes diseases mainly by organ system-- a common, and logically coherent method. But our patients don't present their problems this way. A patient's chest pain may turn out to be cardiac, respiratory, or musculoskeletal, and we may never find out which. A chapter on chest pain could help us to distinguish between the three, and discuss appropriate care even when the diagnosis is uncertain. Similarly, a patient's altered mental status may be neurologic (e.g. due to a stroke), or endocrine (due to a diabetic emergency). A chapter on AMS would tell the EMT to look at the patient's blood pressure as a clue to which is which.
Once again, there aren't many books written for the EMT-B, and this is almost as good as any other. If you're enrolling in an EMT course, you probably don't have much choice but to buy it. If you're an instructor choosing a book for your class, do the world a favor: write a better one.
