PubMed Central Abstract of study examining the Association of Cerebral Palsy with Other Disability in Children with Perinatal Arterial Ischemic Stroke

Instead of putting patients on an operating table for invasive imaging procedures such as cerebral angiography, physicians who use ultrasound can wheel a scanner bedside and obtain 3D images of the brain's arteries. AACPDM - http://www.aacpdm.org/index

NIH PubMed Central Archives of Disease in Childhood - Umbilical venous blood ph: a useful aid in the diagnosis of asphyxia at birth. Umbilical venous blood, and umbilical arterial blood pH, PO2, PCO2, and base excess were determined in 453 term infants at birth. The results indicate that umbilical venous blood pH, and umbilical arterial blood pH are significantly related to each another.

1992 Study to determine if there was a significant association between an intrapartum amniotic fluid index (AFI) < or = 5.0 cm and neonatal acidosis (umbilical arterial pH < 7.20 or metabolic acidosis [umbilical arterial pH < 7.20 and base deficit > 10 mEq/L]).

PubMed Study Abstract: Ten indicators available during the first two hours of life, such as clinical criteria of neonatal distress and postnatal arterial blood gases, were compared with the neonatal neurological course in sixty full term newborns with significant birth asphyxia in order to test their value for the diagnosis and the short-term prognosis of severe birth asphyxia. Birth asphyxia was defined as severe when it was followed by symptoms of moderate or severe post-asphyxial encephalopathy.

obgyn.net - Article - Cord blood gases to determine umbilical artery acid-base analysis - Charts and values available on this site outlining Normal fetal cord blood pH and gas values and abnormal fetal cord pH and gas values.

Clinical Chemistry - 1997 NACB Symposium - Evaluation of the newborn's blood gas status - This paper discusses considerations for interpretation of blood gases in the newborn period. Blood gas measurements and noninvasive estimations provide important information about oxygenation. Its determined that Blood gas measurements and complementary, noninvasive monitoring techniques provide the clinician with information essential to patient assessment, therapeutic decision making, and prognostication. Blood gas measurements are as important for ill newborn infants as for other critically ill patients, but unique challenges are provided by rapidly changing physiology, difficult access to arterial and mixed venous sampling sites, and small blood volumes.

University of Weatern Ontario, Canada study to estimate to what extent computerized fetal heart rate (FHR) parameters are affected by labor and to estimate the relationship between FHR parameters and the degree of fetal metabolic acidosis in laboring patients at term. Study concluded that in term pregnant women with reassuring FHR tracing, labor causes an increase in both short- and long-term FHR variation, which was abolished in the presence of nonreassuring FHR tracing. Computer-derived FHR parameters studied during the last hour of labor were not correlated with the degree of metabolic acidosis as measured in the umbilical artery at birth.

PubMed abstract: Neonatal depression and birth asphyxia in the low birthweight neonate. In 392 low birthweight neonates, acidosis as evident from umbilical artery pH 7.1 or less was strongly associated with Apgar score 6 or lower at 1 minute. However, most cases that were depressed (Apgar score 6 or lower at 1 minute) were not acidotic. Neonatal depression was most strongly and directly correlated with gestational age. Neonatal depression and birth asphyxia are distinct entiti

PubMed Abstract of study to determine the association of hypotonia and depression in neonates at or near term with metabolic acidemia at birth (umbilical arterial pH<-12 mM).
