There are straightforward how-tos on every aspect of medicine easily available for everyone, and no need to turn to survivalist guides, either. How do you think doctors learn this stuff? The exact same medical textbooks we use are sold freely to everyone who wants them, and there's a youtube video for practically every medical technique. I learned to suture from a textbook and an online vid, practiced on a piece of foam and some pig skin, and managed a perfectly serviceable if not quite cosmetically perfect suture on my first attempt on a living patient.
