Trial Parameters
Brief Summary
The primary objective of this study is to describe the pattern of renal tissue oxygen saturation (SrSO2) using near-infrared spectroscopy (NIRS) in premature infants \<30 weeks gestational age. The secondary objective of this study is to evaluate prenatal and postnatal risk factors for acute kidney injury (AKI) in premature infants \<30 weeks gestational age. The investigators will also compare various rates of complications including death, length-of-stay, and prolonged duration of mechanical ventilation, among others.
