Cranial US

Home

Cranial ultrasounds are performed routinely on preterm neonates.

After a review of the database, plus the literature we have modified the usual routine for minimum surveillance cranial ultrasounds.

Gestation	Day 0-1	Day 7-10	Day 28	Day 60	Day 90
30-31+6	no	yes	no	no	no
28-29+6	no	yes	yes	yes	no
Less than 28 weeks	yes	yes	yes	yes	yes

Cranial USS can be ordered at any time if there is a clinical indication.

Clinical indicators for a non-routine cranial USS:

• Preterm infants with chorioamnionitis demonstrated on placental pathology
• Meningitis
• Neonatal encephalopathy: HIE, seizures or metabolic
• Antenatal cranial abnormality or bleeding diathesis
• Significant deterioration where intracranial pathology is suspected: Hypotension Pneumothorax

Further imaging following the diagnosis of intracranial pathology will be dependant.by the clinical picture.
