Nephro Flashcards
Hematuria
Glomerular origin is suggested by
Dysmorphic erythrocytes
Anion gap is calculated as
AG= Na - ( CL + Hco3)
Delta-Delta ratio
= ( AG - 12 ) / ( 25 - HCO3)
Delta- delta ratio interpretation
< 1 ; + NAGMA
1-2 ; pure HAGMA
> 2 ; + metabolic alkalosis
Osmolar gap formula
= measured osmolality - calculated osmolality
Plasma osmolality is calculated by
( 2x Na ) + Glucose + urea
causes of Metabolic alkalosis
VALH
1. Vomiting
- Antacid use
- Loop diuretics
- Hyperaldosteronism
NAGMA causes
HARD ASS
1. hyperalimentation ( TPN)
- Addison disease
- RTA
- Diarrhea
- Acetazolamide
- Spironolactone
- Saline infusion
HAGMA causes
Renal: uremic acidosis when GFR < 15-20
Extrarenal :
Lactic acidosis
DKA
Starvation ketoacidosis
Alcoholic keto acidosis
Poisoning
Treatment of chronic HTN in pregnancy if BP
SBP >= 160 or DBP > =110
Treatment of Lithium induced DI
Amiloride
Ttt of RTA type 1
Potassium citrate
Ttt of RTA type 2
Bicarbonate + - thiazide
Ttt of RTA type 4
Correct the underlying cause
Thiazide or loop
Causes of Urine Cl< 15
Vomiting
Nasogastric suction
Diuretics
