Advances in clinical application of near-infrared spectroscopy in monitoring oxygen saturation in brain tissue of premature infants / 国际儿科学杂志

ABSTRACT

Compared with percutaneous oxygen saturation(SpO 2), cerebral regional tissue oxygen saturation(CrSO 2)reflects the mixed oxygen saturation of brain tissue, and its change is closely correlated with the metabolism of brain tissue after birth.Near-infrared spectroscopy(NIRS)is a non-invasive continuous monitoring technology, which can provide information about changes in blood flow and damage of brain tissue.For now, NIRS has been used as a routine monitoring method in some neonatal intensive care units.Although the current research has not clearly proposed the diagnostic significance of NIRS in neonatal brain injury, current studies have found that detecting changes in CrSO 2 and corresponding interventions in abnormal values can reduce the incidence of brain injury in premature infants.The relationship between CrSO 2 and brain injury and the factors affecting CrSO 2 are still the current research hotspots.This article reviews the factors affecting the changes of CrSO 2 and clinical interventions to maintain its stability.
