ABSTRACT
Objective We aimed at assessing the association between superior vena cava flow (SVCf), regional (cerebral) tissue oxygen saturation (rSO2), and cerebral fractional oxygen extraction (CFOE) during the first 48 hours of life and 2-years neurodevelopmental outcome of very low-birth-weight infants (VLBW). Methods We prospectively studied 60 VLBW infants admitted to our neonatal intensive care unit; rSO2 was continuously monitored with near-infrared spectroscopy during the first 48 hours of life, SVCf was measured at 4 to 6, 12, 24, and 48 hours, and CFOE was calculated. Neurodevelopmental outcome was assessed at 24 months corrected age. Results The mean gestational age at birth was 27.9 weeks (standard deviation 2.4); 8 infants died in the first 3 months of life, 6 were lost to follow-up, 46 survived and were followed up. At 24 months, 6 (13%) and 7 (15.2%) infants developed minor and major sequelae, respectively. Infants who died had higher CFOE (p < 0.001) and lower SVCf (p < 0.001) than infants surviving with sequelae. In turn, these had higher SVCf between 24 and 48 hours than those without sequelae (p < 0.001). Conclusion SVCf, rSO2, and CFOE patterns in the first days of life suggest cerebral hyperperfusion, related to loss of autoregulation and/or use of inotropic drugs, as a potential mechanism of cerebral injury.
