From bruised fingers and drunken brawls to numerous injuries in car accidents and a worldwide epidemic—at the emergency department, you have to be ready for anything unexpected. Every patient here is a source of small chaos: you must determine how urgent and complex their case is, examine their medical history, identify the causes, carry out an exam or surgery, and most importantly, believe that they will leave the hospital in excellent condition. And after each patient, there is always the next one, the next operation, the next emergency—whose consequences require the involvement of several specialists. Timely emergency care and choosing the right course of treatment is possible only thanks to the coordinated work of the team, strength of spirit, and boundless desire to help everyone. This is what the authors talk about, as well as about the most memorable patients, the beginning of a global epidemic, and more.
