[Neurosonography and creatine kinase BB level in premature infants with perinatal risk factors]

High-resolution real time ultrasound scan is used for early diagnosis of PIVH in neonates. Furthermore, in term infants an increase of serum Creatine-Kinase BB (CK-BB) values has been found to be clinically useful for diagnosis and prognosis of several perinatal cerebrovascular injuries. Eighty-eight preterm infants with different grades of PIVH (I-IV) were studied by serial measurements of CK-BB levels in serum. No statistical correlation was found between enzymatic levels, severity of PIVH and perinatal risk factors (p greater than 0.5).
