Polytrauma is one of the most difficult and complex conditions in emergency medicine. By definition, polytrauma is the simultaneous existence of a serious injury to at least two body regions, where at least one injury or a combination of them endangers the life of the injured person. Due to the complexity of the injuries themselves, as well as insufficiently explained responses of the organism to the trauma itself and to therapeutic procedures, the treatment of polytraumatized patients is one of the most complex in modern medicine. Algorithms are of great help in the modern approach to the treatment of polytrauma, the application of which achieves better results while reducing omissions and errors and raising the quality of healthcare to the highest level. The basic principle of treatment of polytraumatized patients is timely, comprehensive and continuous treatment, which necessarily begins at the place of injury, continues during transport and continues in the hospital or trauma center, with the simultaneous implementation of diagnostic and therapeutic procedures. Prehospital care at the scene of the accident and transport to the hospital within the golden hour is of crucial importance for a favorable outcome. Quality patient care requires a multidisciplinary team and an approach to the patient that manifests itself in the cooperation of outpatient emergency medical care and hospital emergency teams. Each member of the team is equally important and has his own role in care, all with the aim of keeping the patient alive, preventing complications and facilitating post-hospital rehabilitation. In outpatient emergency medicine, the mechanism of injury is important and the first examination is the basis of care for all persons who have experienced trauma. The role of a nurse/medical technician in any of the above situations requires great dexterity, expertise and a lot of knowledge and skills.
