Study Notes
Electrolytes & Blood Products
- Fluids and electrolytes are crucial for maintaining health and function.
- Blood products and transfusions are used to treat various medical conditions.
Electrolytes & Minerals
- Sodium (Na+) is primarily found in extracellular fluid (ECF).
- Normal levels range from 135-145 mEq/L.
- Sodium maintains water balance, osmotic pressure, nerve impulse conduction, and muscle contraction.
Sodium
- Sodium is obtained through diet and intravenous fluids.
- Homeostasis is regulated by the kidneys, which reabsorb most filtered sodium.
- The Renin-Angiotensin-Aldosterone System (RAAS), Antidiuretic Hormone (ADH), and Sympathetic Nervous System (SNS) manage blood pressure and intravascular volume.
- Other hormones and peptides influence sodium excretion and regulation.
Sodium Alterations
- Hyponatremia occurs due to various causes resulting in low sodium levels.
- Causes can be hypervolemic (e.g., heart failure, cirrhosis) or hypovolemic (e.g., diarrhea, vomiting).
- Other causes include salt wasting (e.g., intracranial injury) or euvolemic (e.g., adrenal insufficiency).
- Symptoms include nausea, vomiting, muscle cramps.
- Treatment depends on the underlying cause.
- Hypernatremia is characterized by elevated sodium levels.
- Causes include water loss (e.g., fever, sweating, osmotic diuresis).
- Other causes can be nephrogenic or central diabetes insipidus or excessive sodium administration.
- Symptoms include dehydration or fluid excess, cellular death.
- Treatment depends on the underlying cause.
Potassium
- Most potassium is found inside cells (intracellular).
- Normal levels range from 3.5-5.2 mEq/L.
- Potassium is vital for cell membrane excitability (nerves, muscles, heart).
- It also impacts kidney function, vasodilation, thrombus inhibition, and osmotic pressure.
- Kidney function, hormones like aldosterone, glucocorticoids, catecholamines, and arginine vasopressin play a role in potassium homeostasis.
Potassium Alterations
- Hypokalemia occurs due to various factors like diuretics, beta agonists, insulin, antibiotics, catecholamines or GI losses (e.g., laxatives, bowel preparation).
- Symptoms include muscle weakness, cramps, rhabdomyolysis, ileus, nausea/vomiting, and dysrhythmias.
- Treatment focuses on determining the cause and potassium replacement.
- Hyperkalemia is potentially life-threatening stemming from potassium redistribution, or inhibition of secretion.
- Causes include aldosterone antagonists, beta antagonists, NSAIDs, chemotherapy.
- Symptoms include widened QRS complex, cardiac conduction block, paresthesias, and muscle weakness.
- Treatment aims to rapidly restore potassium balance.
Magnesium
- Magnesium (Mg) is mainly found inside cells (intracellular).
- Normal levels range from 1.7-2.4 mg/dL.
- Magnesium contributes to various cellular functions, including protein synthesis, neuromuscular function, and antiarrhythmic effects.
- It also promotes vasodilation, BBB stabilization, and reduction in anesthetic requirements.
- Kidney function is a key regulator.
Calcium
- Most calcium is found in the skeleton.
- Normal ionized calcium levels range from 2 - 2.5 mEq/L.
- Normal levels range from 8.5 - 10.5 mg/dL.
- The body regulates calcium through vitamin D, parathyroid hormone (PTH), and calcitonin. These regulate intestinal absorption, renal reabsorption, and bone turnover.
Calcium Alterations
- Hypocalcemia occurs in diverse conditions, including low albumin level, vitamin D deficiency, hypoparathyroidism, pancreatitis, chronic renal failure, and citrate binding.
- Symptoms include neuromuscular problems, seizures, and dysrhythmias.
- Hypercalcemia results from conditions such as hyperparathyroidism, parathyroid adenoma, malignancies.
- Treatment aims to enhance renal calcium excretion with fluids, corticosteroids, biophosphonates, calcitonin.
- Emergency treatments require hemodialysis for severe cases.
Phosphate
- Phosphate primarily resides celluarly (intracellular).
- Normal levels range from 3-4.5 mg/dL.
- Phosphate is essential for energy metabolism (influencing ATP production), intracellular signaling, and immune/coagulation system function.
- Regulation involves an interplay between vitamin D, parathyroid hormone, and renal reabsorption.
Body Fluid Compartments
- Total body water accounts for 55-60% of total body mass in healthy individuals.
- About two-thirds are intracellular fluid (ICF) and one third are extracellular fluid (ECF).
- ECF can be further divided into interstitial fluid and plasma.
Intraoperative Fluid Management
- Intraoperative fluid management strategies are specific.
- Volume responsiveness is crucial.
- Appropriate choice of fluids depends upon individual patient conditions and circumstances.
Blood Physiology & Transfusion
- Blood components include cells (red blood cells, white blood cells, and platelets) and plasma.
- The composition of blood varies.
- Sources of blood cells are the bone marrow, liver, and spleen.
Blood Storage and Transfusion
- Proper storage is essential for blood products to maintain their quality until use.
- A variety of situations may call for transfusions and their related risks.
- Monitoring for adverse reactions and complications is essential.
