Jittery Baby
Jittery vs. seizure?
Jittery- normal eye movement, hands stop moving if they are grasped
Seizures- eye movements can be abnormal (i.e. staring, blinking, nystagmoid jerks, or tonic horizontal eye deviation; hands continue to move if grasped
Benign Myotonic activity- usually jerking of one extremity during sleep, benign
EEG positive with seizures and jitteriness they are negative
Important History information:
1) History of birth asphyxia or risk factors of sepsis
2) Blood glucose level
3) How old is the baby?
-At birth:
- maternal anesthetics
- day #1 metabolic abnormalities: hypoglycemia, hypocalcaemia, hypoxic-ischemic encephalopathy (presents at 6-18 hours of life and worsens at 24-48)
- day #2-3 drug withdrawal and meningitis
- day #5 or greater- hypocalcemia , TORCH infections (toxo, other, rubella, cytomegalovirus, and HSV)
- more than 1-2 weeks- methadone withdrawal
Differential DX
- hypoxic-ischemic injury
- intracranial hemorrhage
- neonatal cerebral infarction
- metabolic abnormalities
- infection
- neonatal withdrawal
- inborn errors of metabolism
- maternal anesthetic agents
- drug toxicity
- developmental abnormalities – cerebral malformations
- CNS trauma
- Hydrocephalus
- Polycythemia
Work-up-
History-when, how long, when in relation to feeding and sleeping
PE- neuro exam, moros, rooting and looking for cns abnormalities, tuft of hair or skin findings above the spinal cord or AF
Labs- glucose, sodium, calcium and magnesium, utox
Infection work up- cbc with diff, blood, urine and csf (+/-) cxs
Radiologic studies- ultrasound of head- looks for bleeds and may see cysts ( dandy-walker malformation)
CT of head- better for subgaleal bleeds and congenital malformations
EEG- recommended after the seizure activity has been documented several times.
Immediate Treatment for seizures-
1) rule out hypoxia
2) check glucose level
3) obtain stat calcium, sodium and magnesium
4) anticonvulsant therapy- so, if everything else has been corrected and still seizing,
- phenobarbital 20mg/kg for loading , can give up to 40mg/kg if have not stopped
- phenytoin if still seizing 20 mg/kg
- benzos- maybe used but may cause respiratory failure but, may already be intubated.
