BUN and creatinine

Definition

stable--> dx: renal insufficiency

Nitrogen retention & hypernatremia-->dehydration

Term

Postmortem

Sodium, chloride & potassium

Test?

Definition

[Na+]v & [Cl-]v --> stable

[K+]v-->rises linearly-->postmortem interval

[K+]v nml= 15mEq/L

Term

Postmortem digoxin levels

Digoxin toxicity

Definition

Cannot dx digoxin toxi based only on p/m digoxin levels Lipotrophic drug -->p/m -->reenters serum

Volume overload,hepatorenal failure,pregnancy,hypertension,nl infants --> endogenous digoxin like substances

Term

Postmortem

[Tryptase]serum = normal

?Info

Stable in serum for several days

if elevated --> nonspecific in anaphylactic deaths

Term
