The systemic manifestations of "asphyxia" were evaluated prospectively in
35 consecutively intubated term newborn infants. The following systemic
organ injuries were identified most often: (1) renal, ie, oliguria less
than 1 mL/kg per hour for at lest 24 hours (40%), an elevated urinary
beta-2-microglobulin concentration (57%), azotemia (11%), and an elevated
serum creatinine level (17%); (2) central nervous system, ie,
hypoxic-ischemic encephalopathy (including seizures) (31%) or an abnormal
cranial ultrasound scan, ie, diffuse parenchymal echogenicity, slitlike
ventricles, and poor visualization of the sulci, and/or intracranial
hemorrhage (26%); (3) cardiovascular, ie, an abnormal echocardiogram (25%)
or abnormal electrocardiogram (11%); (4) pulmonary complications, including
persistent pulmonary hypertension (23%); and (5) gastrointestinal
complications, which were rare. Traditional markers of fetal distress were
not related to the frequency and/or distribution of systemic organ injury.
An important implication of this study relates to the recognition of the
extent and distribution of organ injury in the "asphyxiated" infant.
