By the end of the session the student
should be able to
◦ Outline the common electrolytes, etiology
of excess or deficiency and treatment
Potassium
Potassium
is mostly contained in the
intracellular compartment.
serum
potassium levels do not indicate the
total body potassium accurately.
Blood
pH levels affect the
distribution of potassium
between the intracellular and
extra cellular compartments.
A
low pH shifts potassium out of the cell,
while alkalosis drives potassium into the
cell.
A
handy rule is that each 0.1 unit change
in pH results in a 0.3-0.6mEq/L change in
serum potassium.
The
intracellular potassium concentration
affects cellular enzymes and intracellular pH.
Low intracellular potassium raises the pH,
whereas high intracellular potassium lowers
the pH.
Potassium
is necessary for maintaining cell
volume because of its important contribution
to intracellular osmolality
Potassium
is plentiful in food.
Dietary consumption varies
1–2 mEq/kg is the recommended
intake.
The
intestines normally absorb approximately
90% of ingested potassium.
Most absorption occurs in the small intestine,
whereas the colon exchanges body potassium
for luminal sodium
There
is some loss of potassium in sweat,
but this is normally minimal.
The
colon has the ability to eliminate
some potassium.
Potassium
is freely filtered at the glomerulus
90% is reabsorbed before the distal tubule
and collecting duct, the principal sites of
potassium regulation.
Hypokalemia
Hypokalemia
is defined as a serum
potassium level of < 3.5mEq/L.
Hypokalemia
often results from
chronic diuretic use
unreplaced electrolyte loss from NG
drainage.
