Changes in Cerebral and Splanchnic Tissue Oxygenation During Enteral Feeding in Premature Infants with Duct-Dependent Congenital Heart Disease

Abstract Introduction This study aims to compare cerebral and splanchnic regional oxygen saturation(rSO2) in premature infants with duct-dependent congenital heart disease (CHD) using near-infrared spectroscopy (NIRS) with that of case-control premature infants without CHD. Materials and Methods Premature infants with duct-dependent CHD requiring prostaglandin E1 (PGE1) for more than 10 days and control preterm infants (without CHD) were monitored for 36 hours using NIRS to assess cerebral and splanchnic rSO2. Both groups received gavage enteral feeding. Multiple measurements were taken around feeding at three d…
