Abstract

Purpose: Near infrared spectroscopy (NIRS) has been proposed as a biomarker to evaluate splanchnic oxygenation (sRSO2) in preterm neonates with mesenteric desaturation being predictive of necrotizing enterocolitis (NEC). The two sites commonly described for placement of NIRS probes on the abdomen include infra-umbilical and left para-umbilical. However, it may not always be possible to place NIRS probes at a single site for prolonged monitoring. The objective of this study was to assess limits of agreement between sRSO2 obtained simultaneously using NIRS probes placed over four sites on the abdomen. Methods: Since preterm infants have smaller …
