Tx of SYMPTOMATIC hypONa - CORRECT ANSWER - -ABSENCE of severe sx
(coma/seizures): increase [plasma Na] by 4-6 mmol/L in first 24 HRS if chronic or duration
unknown.


-SEVERE: raise [serum Na] by 4-6mE/L over the first 6 HRS w/ 3% saline (513 mEq of Na).


Na requirement= TBW (desired Na-serum Na)


-Active SEIZURES: increase [Na] by 4-6mEq in FIRST HR w/ 100-150cc bolus of 3%.
---Raise [Na] by 9-12mEq in 24 HRS /18 mEq in 48 HRS.


TURP Syndrome - CORRECT ANSWER - Cx by absorption of hypOtonic irrigation soln
(~6-8L of glycine/sorbitol/mannitol) used during TURP (also seen in its post-op hysterectomy) --
> increased ADH secretion in post op period-->Hyponatremia and water intoxication (sx
resembling CVA in elderly)-->hypOnatremia, volume overload, neuro sx.


HypERnatremia Dx - CORRECT ANSWER - U osm should be >700 when [serum
Na]>147
Uosm<Plasma osmol --> renal free H20 loss (DIABETES INSIPIDUS)

, Uosm 300-600: partial DI, osmotic diuresis, psychogenic polydipsia


Water deprivation test - CORRECT ANSWER - Used to dx partial CENTRAL or
NEPHROGENIC DI cx hypERnatremia


Water is restricted
-if Uosm normalizes-->DI r/o
-if Posm approaches 300 or Uosm does NOT change w/ increasing Posm--> administer AVP
---if Uosm INCREASES>50%-->CENTRAL DI
---if Uosm w/ NO CHANGE-->NEPHROGENIC DI


HypERnatremia Tx - CORRECT ANSWER - -Correct half of the deficit w/n 24 HRS,
max: 8-10mEq/day
-Estimate FREE WATER DEFICIT
---TBW x [Serum Na/140-1)
----TBW Males: 0.6 x Wt(kg)
----TBW Females: 0.5 x Wt (kg)
-Correct with hypotonic IVF or PO free water
