Hi,
Hypocalcemia is a common cause of
convulsion in infants. Usually this responds to 48 hours of IV calcium infusion followed by oral.
In severe cases, or cases which recurs after IV correction, as happened here, we need to look for any underlying cause that can be treated accordingly.
Common causes include low blood
magnesium level, vitamin D deficiency,
renal dysfunction and low para thyroid hormone level. So in such cases, I used to order few more lab tests, in a step wise manner- renal function test, phosphorous level, serum magnesium, vitamin D level, and
parathyroid hormone level. Your doctor will guide you.
Hope I have answered your question. Let me know if I can assist you further.
