P91.811

Clinical Causes: Birth asphyxia (lack of oxygen during birth) Infections contracted before or during birth, such as meningitis or encephalitis Trauma during delivery, including neonatal injuries Metabolic disorders inherited or acquired around the time of birth Prenatal conditions affecting fetal brain development Complications related to maternal health issues, like preeclampsia or placental issues

Key Symptoms: Altered level of consciousness, such as lethargy or irritability Poor muscle tone or floppiness Seizures or abnormal movements Difficulty feeding or poor suck reflex Respiratory distress Abnormal reflexes or responses Poor cry or weak reflex responses Signs of increased intracranial pressure, like bulging fontanel or abnormal eye movements

Diagnosis Path: Detailed medical history focusing on the perinatal period Physical and neurological examinations to assess reflexes, muscle tone, and responsiveness Laboratory tests, including blood work and cultures to identify infections or metabolic issues Brain imaging techniques such as ultrasound, MRI, or CT scans to visualize brain structures and identify damage Electroencephalogram (EEG) to detect abnormal brain activity, including seizures

Treatment Protocols: Supportive care in a neonatal intensive care unit (NICU), including respiratory support if needed Cooling therapy (therapeutic hypothermia) to minimize brain injury if initiated within the first 6 hours after birth Management of seizures with anticonvulsant medications Fluid and nutritional support to ensure proper growth and development Treating infections with appropriate antibiotics or antivirals Addressing metabolic or other underlying disorders as identified Early initiation of physical, occupational, and speech therapy to aid developmental progress
