Intraventricular Hemorrhage (IVH)

Risk Factors & Presentation

• Extreme prematurity (< 32 weeks) and very low birth weight
• Fluctuating cerebral blood flow (pneumothorax, rapid fluid boluses, uncoordinated mechanical ventilation)
• Clinically silent in ~50% of cases
• Severe presentations: bulging fontanelle, sudden drop in hematocrit, apnea, bradycardia, seizures, flaccidity

Screening & Diagnosis

• Routine screening Head US for all infants < 32 weeks or < 1500g at 7-14 days of life
• Papile Grading I-IV (I: germinal matrix, II: inside ventricle without dilation, III: ventricle dilation, IV: parenchymal extension)

Management & Follow-up

• Prevention: Delayed cord clamping, antenatal corticosteroids, maintain neutral head positioning
• Supportive care: maintain stable hemodynamics and avoid rapid volume shifts
• Monitor for Post-Hemorrhagic Hydrocephalus (PHH)
• Intervention: Consider temporary reservoir placement or ventriculoperitoneal (VP) shunt for progressive PHH

Neurocritical Care & Monitoring

• Maintain strict midline head positioning, elevate head of bed 15-30 degrees to optimize venous return and minimize ICP.
• Phenobarbital dosing: 20 mg/kg IV loading dose (push rate < 1 mg/kg/min to avoid cardiovascular collapse).
• Continuous aEEG (Amplitude-integrated EEG) monitoring for minimum 72 hours for all encephalopathic infants.
• Minimal handling protocol: cluster nursing care, restrict visitors, reduce ambient noise and keep isolette heavily shielded from light.
• Assess anterior fontanelle fullness and head circumference daily.

Standardized Discharge & Follow-Up Criteria

• Adequate weight gain explicitly > 15-30g/day over a continuous 3-5 day period.
• Maintenance of temperature in an open crib with standard clothing for 48 hours.
• Successful completion of the 90-120 minute Infant Car Seat Challenge.
• Caregiver successfully completed CPR training, rooming-in, and independent medication administration.
• Referrals placed for High-Risk Infant Follow-Up Clinic, Early Intervention (PT/OT), and appropriate sub-specialists.

Diagnostic & Management Algorithm

• IVH Risk Mitigation: [START] Premature Infant < 30 weeks -> [ACTION] Delayed Cord Clamping / Delivery Room stable temp -> [MONITOR] Keep Head Midline / Elevate 30 degrees -> [EVALUATE] Head Ultrasound at day 7
