TURP syndrome is
hyponatremia d/t absorption of irrigation fluid
give hypertonic saline
LR should be avoided in
hypercalcemic crisis
very high serum potassium levels with end stage renal disease
large volumes of stoma output leads to
loss of sodium, potassium, bicarbonate, and bicarbonate like anions (propionate, acetate, butyrate)
non anion gap (hyperchloremic) metabolic acidosis
GOO and vomiting leads to
hypokalemic, hypochloremic metabolic alkalosis
prolonged QT interval
hypocalemia
hypercalcemia
polyuria
treatment of chronic euvolemic hyponatremia
fluid restriction
how much sodium do you need a day
2 mEq/day
how much potassium do you need a day
1 mEq/day
how much water do you need a day
30 ml/kg + whatever loses
MC electrolyte abnormality of Sheehan syndrome is
hyponatremia
how much is lost by saliva
1500 ml
how much is lost by stomach
1-2 L
how much is lost by biliary
500 ml
how much is lost by pancreatic
500-1500 ml
how much is lost by small bowel
1500 ml
the small bowel absorbs
8500 ml
the large bowel absorbs
400 ml
preferred maintenance fluid for peds
D5 NS with 20 K
electrolyte abnormalities with tumor lysis syndrome
hyperkalemia
hyperphosphatemia
hypocalcemia
AKI
does rhabdomyolysis cause non anion gap or anion gap acidosis?
non anion gap metabolic acidosis
non anion gap acidosis causes
HAARDUPS hyperalimentation acetazolamide amphotericin B renal tubular acidosis (rhabdo) diarrhea ureteroenterostomy pancreatic fistula sulfamylon (mafenide acetate - inhibits carbonic anhydrase)
lithium toxicity can result in
hypercalcemia
hypermagnesemia
hypocalciuria
secondary hyperparathyroidism
decreased or normal calcium
increased PTH
increased or decreased phosphate
