Pediatric Problem Solving - Case 24

Pediatric Problem Solving – Case 24
A 1 day old infant develops jitteriness and convulsions . He was born at 34 weeks gestation to a woman whose pregnancy was complicated by diabetes mellitus and pregnancy induced hypertension.

Which of the following serum values could explain his condition?

A. serum bicarbonate level of 22 mEq/dl

B. serum calcium of 6.2 mg/dl

C. serum glucose of 45 mg/dl

D. Serum sodium of 138 mEq/dl.

Explanation of the case:

convulsions is due to :

1. premature infant (34 weeks)

2. Infant of diabetic mother develops hypocalcaemia in the first 3 days, hypocalcaemia → convulsions.

3. Prematurity induce hypocalcaemia.

Choice (A) : point against : normal level of bicarbonate

Choice (B) : the right choice :serum level below 7 mg, hypocalcaemia

 Choice (C): point against: normal level of glucose.

 Choice (D): point against: normal level of sodium.
