Neonatal Convulsions
A convulsion is defined clinically as a paroxysmal alteration in neurologic functions, ie, bebovioral, notor or autonomic functions or all three occurring within 28 days of age.

A neonatal convulsion may be difficult to recognize became sometimes it presents very subtly abnormal gase, smacking of lips, blinking of the eyes, abnormal posturing, apnee spells and stiffening of the limbs.

Causes:
A.      Perinatal complications – 25% causes of
a.                                             Perinatal & birth injury cerebral amoxid
b.                                             Intracranial – IVI+, subdural & subarachnoid
B.      Inflations:
  a.    Meningitis
  b.    Enaphalitis
  c.    Tetanus
  d.    Septicemia
C. Metabolic:
  a.    Hypoglycemia
  b.    Hypocalcaemia
  c.    Hyponotrcemia
  d.    Hypomagnesaemia
  e.    Hyperbilirulinemia (kernicterus)
  f. Pyridoxine deficiema
  g.    Drug  withdrawal
  h.    Inborn errors of metabolism.
D. Developmental  of brain
E.  Unknown – 25%
  1st 3 day:  1.   Perinatal asphyxia, trauma
2.         Early neonatal lypocalemia
3.         Hypoglycemia
4.         IVH
5.         S. Electrolyte disturbance
4-10 days : 1.  Septicemia, meningitis, tetanus
          2.  Late neonatal hypocalcaemia
          3.  S. blatrolyte disturbance
          4.  Kernictarers
> 7 days:     Storage discare
          Metabolic
          TORCH infections
  
Evaluation:
1.         A full prenatal history & neonatalal exam
2.         Date wise onset of convulsion
3.         Lab, assessments:
Blood sugar, calcium, magnesium, sodium CBC, Blood C/S & toxic serum
CSF exam cranial USG?CT serum.
Treatment:
1.                     Look for vital signs & maintain ABC
2.                     Therapy should be directed to underlying cause

 3.                     Initial measures:
1/v 10% DA → 2-4 ml/kg over 5 min
          ↓ No improvement
Inj. 10% calcium gluconate ml/kg over 10 mins
          ↓ No improvement
Inj. phenobarleitme 10-20 mg/kg slat over 5 mins
This may be separated once after 10-15 mins if convulsion persists
              ↓ No improvement
     Inj. diazpass 0.3 mg/kg – ½ star storly or 0.5 mg/kg PR Co.2 ml dilute with 0.8 ml D normal su….
              ↓ No improvement
     Inj. Ampicillen 10 mg/kg + Inj. Gentamices 5 mg/kg 1/2 & refer cif nuded)
If 1v line can not be established →
Inj. Diazepam 0.5 mg/kg –PR + Inj. Phenobarbitone 20 mg/kg 1/m + Inj. Ampicillin & Gentamicin & refer immediately.

Maintenance dise – Phenobarbitals 5 mg/kg daily or twice dose.

Donation:
  1.neurologically normal at discharge – discontinue treatment & continue if abnormal.
The optimal duration has not been established. Some recommended for a prolonged period, have been absent for 2 wks.

Prognosis:
1.  MR – 15%
2.  Neurologic sequelal – (Mental retardation 30% motor definite………)
3.  Normal outcome 56%


In an individual case, prognosis is estimated by level of maturity, Underlying iliology, EEG, neurologic exam. & imaging study’s of brain such as CT
