[Creatine kinase BB and lactate in the cerebrospinal fluid of neonates and infants with perinatal injuries of the CNS].

A study was made of the content of creatine kinase-BB (CK-BB) and lactate in cerebrospinal fluid (CSF) of 202 neonates and infants with perinatal CNS injuries. The relationship was found between the rise of the CK-BB content and the gravity of perinatal CNS injuries. The highest content of CK-BB in CSF was marked in neonates with cerebral disorders complicated by infectious and inflammatory diseases (pneumonia, sepsis). Within the first 5 days of life, the children of this group demonstrated the relationship between the content of CK-BB and lactate of CSF. The measurement of the content of CK-BB in CSF should be used for early diagnosis, assessment of the gravity and course of perinatal CNS injuries in neonates and in infants.
