Abstract |
The prognostic value of cerebrospinal fluid (CSF) lactate concentration after an hypoxic-ischemic brain insult was evaluated. Three groups of neonates were studied and followed. Group 1A included 19 asphyxiated neonates who subsequently developed normally, Group 1B included 6 asphyxiated neonates who died or developed neurologic sequelae, and Group 2 consisted of 20 control (comparison) infants. A CSF sample was obtained within the first day of life for cytochemical analysis, culture, and lactate determination with simultaneous determination of serum lactate. The mean CSF lactate level in Group 1B (4.5 mmol/L) was significantly higher than in Group 1A (2.5 mmol/L) (p less than .001). In comparison to the highest CSF lactate concentrations in the normal range in Group 2 (2.7 mmol/L), all Group 1B neonates had elevated CSF lactate levels, and eight neonates (34%) of Group 1A had increased levels. A correlation was found between blood and CSF lactate levels in asphyxiated infants (r = .42, p less than .05), but its meaning is uncertain. We conclude that CSF lactate determinations may be helpful in the evaluation of perinatal hypoxic-ischemic encephalopathy.
