Acute systemic organ injury in term infants after asphyxia.

Overview

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.
