Mythbuster: Calcium Gluconate Raises Serum Calcium as Quickly as Calcium Chloride
LET’S START WITH THE FACTS
- We know that calcium chloride (CaCl2) provides 3 times more elemental calcium than an equivalent amount of calcium gluconate.
- So, CaCl2 1 gm = calcium gluconate 3 gm.
CLINICAL QUESTIONS
- Does CaCl2 have better bioavailability than calcium gluconate?
- Does calcium gluconate have a slower onset of action because it needs hepatic metabolism to release the calcium?
Which is a better prognostic tool in geriatric trauma, traditional vital signs or lactate level?
