Preliminary exploration of tissue oxygen saturation index using near-infrared spectroscopy in two infants of neonatal catheter-associated venous thrombosis

Background

Near-infrared spectroscopy (NIRS) is commonly used for monitoring oxygen saturation in brain and abdominal tissues, while reports on the monitoring of local tissue oxygen saturation in limbs are very limited. This study observed the changes in limb tissue oxygen saturation index (TOI) in two infants of catheter-related venous thrombosis (CRT) and preliminarily investigated their correlation.
