Description of Changes in NIRS as a Function of Ductus Arteriosus Status in Very Premature Babies Born Before 32 WG at the DIJON University Hospital

Centre Hospitalier Universitaire Dijon26 enrolled

Overview

Monitoring patent ductus arteriosus is currently performed using echocardiography, an operator-dependent examination which requires holding the child on their back and which is potentially time-consuming. This test is usually carried out on days 2, 4 and 7 after birth. NIRS (near-infrared spectroscopy) is a non-invasive method of monitoring tissue oxygen saturation using infrared light. The aim of the study was to investigate an association between cerebral and renal NIRS data and ductus arteriosus status obtained by echocardiography.
