[Brain damage in asphyxiated newborn infants: early diagnosis. A follow-up study]
Insights
Newborn brain damage from perinatal asphyxia can be diagnosed early using cranial CT scans and serum creatine phosphokinase-BB (CPK-BB) levels. Prognosis varies by injury type, with intraparenchymal hemorrhage indicating poor outcomes.
Area of Science:
- Neonatal neurology
- Pediatric neuroimaging
- Biochemical markers in neonates
Context:
- Perinatal asphyxia poses significant risks for newborn brain injury.
- Early and accurate diagnosis is crucial for timely intervention and management.
- Neurodevelopmental outcomes are closely linked to the type and severity of brain damage.
Purpose:
- To evaluate the utility of cranial computerized tomographic (CT) scans and serum creatine phosphokinase-BB (CPK-BB) in diagnosing and assessing brain damage in asphyxiated newborns.
- To correlate different types of brain injury with prognosis and long-term neurodevelopmental outcomes.
- To identify specific CT scan findings indicative of evolving brain damage.
Summary:
- Eighty-five asphyxiated newborns underwent cranial CT scans and serum CPK-BB determination. Elevated CPK-BB levels within 24 hours correlated with brain damage severity.
- Identified brain damage types included intraparenchymal hemorrhage (IPH), periventricular-intraventricular hemorrhage (PV-IVH), subarachnoid hemorrhage (SAH), and brain edema (BE).
- Prognosis was linked to injury type: SAH and BE had better outcomes than PV-IVH, while IPH showed poor results. Follow-up CTs revealed ventricular dilation, leukomalacia, cysts, and porencephaly.
Impact:
- Findings aid in the early diagnosis and severity assessment of brain damage in newborns following perinatal asphyxia.
- Establishes CPK-BB as a valuable biochemical marker for neonatal brain injury.
- Provides critical information on the relationship between specific brain injury patterns and long-term prognosis, guiding clinical management and parental counseling.
Abstract:
Cranial computerized tomographic (CT) scan and serum creatine phosphokinase-BB(CPK-BB) determination were done in 85 asphyxiated newborn infants, in some of them, long-term follow-up study including neurodevelopmental assessment and CT scan were also carried out. The types of early brain damage after perinatal asphyxia included intraparenchymal hemorrhage (IPH), periventricular-intraventricular hemorrhage (PV-IVH), subarachnoid hemorrhage (SAH) and brain edema (BE). Serum CPK-BB levels were elevated within 24 hours after the events of asphyxia, and correlated to the severity of brain damage. These findings were helpful in the early diagnosis of brain damage and estimating its severity and prognosis. The types and severity of brain damage were obviously related to prognosis. The prognosis of infants after SAH and BE were better than those of infants with PV-IVH, and infants with IPH showed the poor results. Follow-up CT scans were performed in 30 infants with brain damage. Abnormal changes included ventricular sulcus dilation, leukomalacia, cyst formation (pseudocyst) and porencephalic cavitation (porencephaly).
