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.
