Flashcards in Acid-Base Disorders Deck (11):
1

When should you give bicarb in lactic acidosis or ketoacidosis?

if pH

2

In which types of high anion gap metabolic acidosis should you always give bicarb? (Hint: prevents crossing of blood-brain barrier and urinary loss of toxins.)

ethylene glycol, methanol, and salicylate toxicity

3

What should be given in ethylene glycol, propylene glycol, and methanol toxicity?

fomepizole (or ethanol)

4

What causes D-lactic acidosis?

high-carb meal in pt w/ small bowel resection

5

Causes of high anion-gap metabolic acidosis.

MUDPILES:
Methanol
Uremia
DKA
Propylene glycol
INH/Iron
Lactate
Ethylene glycol
Salycilates

6

Causes of non-anion gap metabolic acidosis.

loss of bicarb (diarrhea, RTA type II) or inability of kidneys to excrete hydrogen (RTA types I and IV, mild-mod renal failure)

7

>90% of metabolic alkaloses are of this type.

chloride-depletion metabolic alkalosis

8

What are the causes of chloride depletion metabolic acidosis?

vomiting, NG tube suctioning, and thiazide or loop diuretic use in edematous pts

9

What is the mechanism of chloride depletion metabolic alkalosis?

the chloridde-bicarbonate exchanger in the distal tubule is suppressed

10

What should be given to pts w/ metabolic alkalosis from NG suction?

NS

11

What should be given to edematous pts w/ metabolic alkalosis from thiazides or loop diuretics who don't respond to stopping the diuretic?

acetazolamide
