Prognoseparameter neurologischer Langzeitschäden asphyktischer Neugeborener nach therapeutischer Hypothermie
摘要
Neonatal encephalopathy (NE) following perinatal asphyxia remains one of the main causes of neonatal mortality and the development of long-term neurodevelopmental sequelae. Therapeutic hypothermia (TH) is currently the only established treatment for moderate to severe NE but there is still a relevant mortality and a high risk of adverse long-term outcomes. Early prognosis regarding the long-term outcome can help to make therapeutic decisions, initiate early neuroprotective and neurorehabilitative interventions and to advise families.
ObjectiveIn this review article we aim to provide an overview of possible parameters to help predict long-term outcomes in neonates with NE following TH.
MethodsWe systematically evaluated possible prognostic parameters to develop a clinically applicable guide to assess the long-term outcome following TH.
ResultsSignificant parameters predicting long-term outcomes in neonates with NE following TH include the lack of normalization of the (a) EEG after 48 h, the permanent absence of a sleep-wake cycle in the (a) EEG and the presence of status epilepticus on the (a) EEG as well as magnetic resonance imaging (MRI) and cerebral ultrasound findings. Standardized neurological examinations are highly informative, particularly regarding long-term motor outcomes. Clinical information in the first hours of life, such as 1‑min, 5‑min and 10 min Apgar index scores, pH, base excess, lactate levels, and Sarnat-Thompson scores do not enable long-term outcome prediction, but help to identify neonates who are likely to benefit from TH.
ConclusionPrediction of long-term outcome in neonates with NE should be made in a synopsis of all clinical, laboratory, radiological and functional diagnostics.
