[Hypoxic-ischemic brain damage in premature newborns]

Area of Science:

• Neonatal Neurology
• Perinatal Medicine
• Neuroscience

Background:

• Hypoxia is a primary cause of cerebral dysfunction in premature newborns.
• Neonatal hypoxic brain damage results in high mortality and lifelong morbidity.
• Neurological diseases arising in the perinatal period are a significant concern.

Purpose of the Study:

• To present data on the prevalence of perinatal neurological diseases.
• To highlight etiological factors of neonatal hypoxia.
• To analyze the pathogenesis, diagnosis, and treatment of hypoxic-ischemic brain lesions.

Main Methods:

• Review of etiological factors contributing to neonatal hypoxia.
• Detailed description of the pathogenesis of hypoxic-ischemic brain lesions.
• Analysis of diagnostic methods and treatment principles for cerebral lesions.

Main Results:

• Key etiological factors for intranatal and early postnatal hypoxia identified.
• Pathogenesis of hypoxic-ischemic brain lesions detailed, including glutathione system, glutamate-calcium cascade, excitotoxicity, necrosis, and apoptosis.
• Advantages and disadvantages of current diagnostic methods discussed.

Conclusions:

• Understanding the pathogenesis of hypoxic-ischemic brain lesions is crucial for managing premature infants.
• Effective diagnosis and treatment strategies are essential to mitigate long-term morbidity.
• Further research into protective mechanisms and therapeutic interventions is warranted.
