Chapter 99 Nervous System Disorders Flashcards
Diffuse sometimes ecchymotic, edematous swelling of the soft tissues of the scalp involving area of the presenting part during vertex delivery. It may extend across the midline or across suture lines.
Caput succedaneum
Lesion on the scalp that is actually a subperiosteal hemorrhage, hence does not cross suture lines.
Cephalhematoma
A fluctuating mass that straddlws cranial sutures or fontanels that increases size after birth. It is secondary to rupture of emissary veins connecting the dural sinuses within the skull with the superficial veins of the scalp.
Subgaleal hemorrhage
Most common typr of skull fracture in the neonate. No symptoms and no required treatment
Linear fracture
Method used to elevate depressed skull fracture
Percutaneous microscrew elevation
T/F majority of subdural and epidural hemorrhages resolve without intervention
T
This should be suspected in all infants with subdural effusion after the immediate neonatal period.
Child abuse
T/F subarachnoid is common in the immediate neonatal period
F
What finding in the lumbar puncture sample suggests subarachnoid hemorrhage?
Elevated rbc
Major neurologic lesions associated with VLBW infants are
IVH and PVL
IVH in premature infant s occur in the
Gelatinous subepyndymal germinal matrix
What birth weight of infants puts them at highest risk for IVH
<1000g
Preferred imaging technique for screening of IVH
Ultrasound
IVH grading: bleeding within the ventricle but without evidence of ventricular dilation
Grade II
IVH grading: bleed confined to the germinal matrix-subepyndymal region
Grade I
