Study Notes

Electrolyte Functions and Roles

Electrolytes play a crucial role in maintaining fluid balance, nerve function, and muscle contractions.

Fluid Compartments

The extracellular fluid (ECF) compartment includes the intravascular compartment, which is the fluid found within blood vessels.

Fluid Balance

"Third spacing" refers to the abnormal accumulation of fluid in the interstitial space, leading to edema and altered fluid balance.

Electrolyte Balance

Sodium is a major cation involved in electrolyte balance.
Sodium is the most abundant electrolyte in the extracellular fluid (ECF) and plays a key role in regulating ECF volume.

Electrolyte Imbalances

Hypomagnesemia signs may include muscle weakness, tremors, and seizures.
Hyponatremia can be caused by excessive fluid intake, heart failure, or liver disease.
Hypokalemia can exacerbate or predispose arrhythmias like atrial fibrillation.
Hypercalcemia is commonly caused by malignant tumors that produce parathyroid hormone-related peptides.
Hypocalcemia signs may include muscle cramps, twitching, and tingling.
Ionized calcium plays a crucial role in neuromuscular transmission, muscle contraction, and blood clotting.

Electrolyte Functions

Aldosterone regulates electrolyte balance by controlling sodium and potassium levels in the body.
Hyperphosphatemia may cause clinical signs such as metastatic calcification, nephrocalcinosis, and soft tissue calcification.
Phosphorus is essential for muscle contraction, acid-base balance, and nerve function.
Hypophosphatemia is commonly caused by malnutrition, diarrhea, and alcoholism.

Renal Function

Severe electrolyte imbalances may require dialysis.
