Introduction: Skin is the largest suface organ of the human body, which is most affected by burns and its protective function is defected. Burns represent a diverse group of injuries in terms of the cause, time and the intensity of the operation agent. Survival of severely burned, the final outcome of the treatment and the weight of the permanent consequences largely depend on the timely and proper first and emergency aid. The approach to the injured in the prehospital environment is specific because it takes into account a whole range of factors encountered in the environment. The time of supply is very important for injured and unnecessary delays in treatment on the ground even can cause death. Purpose: The aim of the thesis is to present thermal burn injury based on literature and describe the course of treatment of the injured in the prehospital environment, and present key complications. The objectives of the thesis with the help of a literature review: to present a burn and specify the types of burn injuries regardless of the perpetrator, describe the treatment of burn injuries in the prehospital environment in accordance with a systematic review of ITLS, present the most common complications in the care of burn injuries. Methods: Descriptive method is based on a systematic review of domestic and foreign scientific and professional literature in the period 2006-2016 using the databases Medline and CINAHL and the COBIB.SI. Results: Burn injury is one of the major causes of death and disability. Serious burn injuries are devastating events that leave patients with long-term physical and psychological challenges. Burn injuries may be extremely complex in their presentation, and any resulting complications may extend the need for expensive long-term management from months to years. Whit a patient with burn injuries at the scene, nurses should identify all risks that could worsen the conditions of the injured and even threaten his/her life. Knowledge of key scientific findings on the care of patients with thermal burn injury in the prehospital environment and prevention of complications that may arise, is important for the work of nurses with those patients. Discussion and conclusion: Quality and scientifically based care at the scene is necessary since proper first aid can have some influence on the extent of the injury. Quality care can reduce the chances of complications, such as hypovolemic shock, infection, and hypothermia.
