A newborn with a positive maternal TORCH screen and a platelet count of 45,000/mm³ with petechiae is at extreme risk for spontaneous intracranial hemorrhage. Immediate nursing actions include:
- Bleeding Precautions: Institute strict minimal handling protocols. Avoid intramuscular injections, rectal temperatures, and vigorous suctioning. Use soft-bristled sponges for oral care and apply pressure for 5-10 minutes after venipuncture.
- Neurological Monitoring: Perform serial head circumference measurements and neurological checks (level of consciousness, pupillary response, motor symmetry) every 1-2 hours. Report any increase in head circumference, full fontanel, or seizure activity immediately.
- Transfusion Preparation: Anticipate an order for platelet transfusion, typically indicated when counts fall below 50,000/mm³ in an actively bleeding or high-risk neonate. Ensure type-matched, CMV-negative, irradiated platelets are available.
- Environmental Safety: Pad the sides of the bassinet, maintain a neutral thermal environment to minimize metabolic stress, and organize care to allow for prolonged, uninterrupted rest periods.
- Parental Support: Explain the rationale for all precautions clearly, emphasizing that these are temporary measures to protect the baby's brain while the underlying infection and thrombocytopenia are treated.
The underlying congenital infection (e.g., CMV) causing the thrombocytopenia must be concurrently managed. Long-term follow-up will include audiology screening and neurodevelopmental assessments due to the dual risks of the infection and potential hemorrhagic insult.
