|
|
What is the first thing to do if an animals tests for hypercalcemia?
|
repeat if it seems false
|
|
|
How many forms is Ca circulated in?
|
three ionized, complexed/chelated and bound
ionized = active Ca is in ECF |
|
|
What is the most common cause of hypercalcemia?
|
neoplasia from a functional adenoma
producing PTH what affects re absorption of bone and tubular re absorption of Ca |
|
|
What is the treatment for hypercalcemia?
|
ID the cause, dilute the Ca with IV saline
when animal is hydrated used furosamide because it inhibits Ca reabsorption |
|
|
What are the functions of glucocorticoids?
|
they decrease bone reabsoption and decrease Ca absoption in the GI and renal tubules
dramatically lowers Ca from the cancer |
|
|
At what Ca serum level will you start to see signs of hypocalcemia? What two things does this result from?
|
< 6 mg/dl
Hypoparathyroidism and eclampsia |
|
|
When does eclampsia occur?
Who does it most commonly occur in? In lactating cat or dog Small breed dogs |
Give calcium gluconate IV slow
ECG and temperature Ca is cardiotoxic and animals with tetany are frequently hyperthermic |
|
|
What is maintenance therapy for tetany?
If she has another litter should supplement continue through delivery? |
Pups should be weaned and put on formula and oral supplements (Tums)
No, make body mobilize Ca from bones |
|
|

|
24-96 hrs
> 8, but < 9.5 mg/dl |
|
|
What is the life long tx for primary hypoparathyroidism?
|
Vit D3- oral Ca is only given in beginning but weaned off
