Abstract [eng] |
A patent ductus arteriosus (PDA) in preterm infants is one of the most debated topics in neonatology. The ductus arteriosus is a vital blood vessel for the fetus, connecting the aorta to the pulmonary artery. At birth, when a newborn breathes and starts using the lungs, the blood flow changes and the PDA becomes unnecessary. However, in preterm infants, PDA does not always close due to the functional immaturity of organ systems. Echocardiography provides real-time data, however, newborn’s hemodynamics is varying and requires continuous monitoring as the condition of newborns, especially preterm infants, changes rapidly. Near-infrared spectroscopy (NIRS) is a simple technique with unique properties offering non-invasive measuring of regional tissue oxygen saturation in real time and continuously. The aim of the research was to assess the impact of blood shunting through the PDA on cerebral and renal regional tissue oxygenation using near-infrared spectroscopy and the impact of medical treatment in preterm infants. The collected data showed that monitoring by NIRS can help to decide on the hemodynamic significance of PDA and the need for treatment. |
