CSF lactate levels in high risk neonates with and without asphyxia. 1980

O P Mathew, and H Bland, and S B Boxerman, and E James

Determination of CSF lactate levels were performed in 150 nonasphyxiated and 46 asphyxiated high risk neonates. Statistical analysis of log lactate levels of nonasphyxiated infants showed significant relationship to gestational and postnatal ages (P < .0001 and < .0002, respectively). CSF lactate elevation was seen in 16/29 infants studied within eight hours of asphyxia in contrast to 0/17 infants studied after eight hours (P < .001). Higher incidence of CSF lactate elevation was seen in term infants (7/8), infants with fetal distress (13/17), and very low Apgar scores (11/18). Seven of eight infants with markedly elevated lactate levels had both fetal distress and very low Apgar scores. CSF lactate determination in the immediate postasphyxial period appears to be an objective way of assessing the severity of cerebral hypoxia.

D005316 Fetal Distress A nonreassuring fetal status (NRFS) indicating that the FETUS is compromised (American College of Obstetricians and Gynecologists 1988).

D001034 Apgar Score A method, developed by Dr. Virginia Apgar, to evaluate a newborn's adjustment to extrauterine life. Five items - heart rate, respiratory effort, muscle tone, reflex irritability, and color - are evaluated 60 seconds after birth and again five minutes later on a scale from 0-2, 0 being the lowest, 2 being normal. The five numbers are added for the Apgar score. A score of 0-3 represents severe distress, 4-7 indicates moderate distress, and a score of 7-10 predicts an absence of difficulty in adjusting to extrauterine life. Score, Apgar
D001238 Asphyxia Neonatorum Respiratory failure in the newborn. (Dorland, 27th ed)
D012306 Risk The probability that an event will occur. It encompasses a variety of measures of the probability of a generally unfavorable outcome. Relative Risk,Relative Risks,Risk, Relative,Risks,Risks, Relative
