TY - GEN A1 - Sobczak, Alina N2 - Patent fetal vessels of the umbilical cord stump provide a unique central line access in the neonatology setting. The aim of the research was to analyze the correlation between the occurrence of thrombosis and bacterial colonization and microstructural changes of the umbilical catheter as a result of interaction with the patient's body, as well as to determine the role of systematic ultrasound examinations in making clinical decisions. It has been shown that catheters are delicate structures that are easily damaged when treated with tweezers, have a rough structure predisposing to coagulation and harden in the vessel over time due to calcification, which can damage the surrounding tissues. For the first time, the usefulness of bedside ultrasound monitoring of umbilical catheters has been described prospectively and its practical application as a safe alternative to radiographic evaluation has been published. The phenomenon of catheters displacement over time in the patient's body and its clinical implications have been demonstrated. The necessity of re-evaluation of the vessel was justified by describing a series of 'casts' visible in the aorta only after removal of the catheter. The nature of bacterial colonization of catheters has been explored, showing that, contrary to popular belief, it does not depend on the duration of the catheterization but on N2 - the patient's defense mechanisms; colonization takes place mainly from the skin and preterm newborns have been found to be the most exposed to it. During the above research, interesting observations were obtained that could be the starting point for further research.
