The installation of a hip endoprosthesis is a complex procedure in which damaged parts or the entire hip joint are replaced, and it is indicated for various diseases and conditions, the most common of which are degenerative diseases. The basic division of endoprostheses is partial and total, and they can be divided according to the indication for installation and the method of fixation of the endoprosthesis. In order to avoid possible complications, perioperative care is carried out by a medical team composed of: nurses/technicians, doctors, anesthesiologists, anesthesiology technicians, psychologists, instrument operators, physiotherapists and many others is important. Perioperative care is carried out in three phases: before, during and after the procedure. The pre-operative phase begins at the moment of the decision for the operation, and the goal is to determine the patient's health condition, possible problems and changes that may affect the operation, and to educate the patient about the expected course and possible outcomes of the operation. Then, there is an immediate preparation in which the surgical field, digestive tract and special preparations are prepared. The patient needs to be reassured and supported before going to the operating room where the next phase begins. During the intraoperative phase, the patient is cared for by the surgical team, which ensures a safe course of the operation. The last phase begins with moving the patient to the recovery room. In this phase, the main role is played by the nurse/technician who monitors the patient's condition and reacts to possible difficulties and complications. The role of the nurse/technician is of great importance during the entire perioperative period. In the postoperative period, it is especially necessary to provide support to the patient during the rehabilitation process and to show him the importance of following all the instructions that are given.
