most common childhood seizure disorder, peaks 12-18 months, most common in boys, core temp 102.2

During febrile seizure what to do give child?

rectal diazepam

when are neonatal seizures common?

first four wks of life generally but most common in first 10 days of life.

true or false: tonic-clonic seizures can occur within the first 4 wks of life.

false

What is a neonates response to stress?

stop breathing

What is the med of choice for neonate seizures?

phenobarbital

What is important in management of neonatal seizures?

adequate ventilation

What is vertebral bodies without protrusion of the spinal cord or meninges? what would u see in assessment?

spinal bifida occulta; normal variant, noticeable dimpling or patch of hair or discoloration of skin.

What is less serious then SB cystica occur when meninges herniate through defect in the vertebrae.

meningocele: skin over sac is intact

What is the most serious form and the spinal cord often ends at the point of the defect?

myelomeningocele
