Elevation in the physiologically important ionized (or free) calcium concentration. However, 40 to 45 percent of the calcium in serum is bound to protein, principally albumin; , increased protein binding causes elevation in the serum total calcium.

Understand the difference between body volume status and serum Sodium concentration. 3. Recognize the different types of intravenous fluids used at bedside. 4. Know the workup for Hyponatremia. 5. Know how to calculate the water deficit in Hypernatremia. ★ Resources Used in This lecture: Slides and Davidson’s Extra Explanation ​ Done by: Mohammad Alkharraz Contact us at: [email protected] ​ Revised by: Nouf Almasoud In this lecture, our goal is to understand sodium and water disorders. The key to unlocking this subject is clearly distinguishing between total body sodium and serum sodium concentration First we will brush on the concepts of body fluids and osmolarity and other basic principles. ★ Body Fluids ● Total body water (TBW)= ○ 60% of weight in males ○ 50% of weight in females ○ It decreases as we increase in age (babies have more TBW than the elderly) ● TBW is divided into ○ ICF (⅔ of TBW) ○ ECF (⅓ of TBW). ECF is divided into ■ Interstitial fluid (¾ of ECF) ■ Plasma (¼ of ECF) ★ Osmosis ○ What is osmosis? ■ It is the movement of WATER from an area of LOW osmolarity to an area of HIGH osmolarity ○ What is osmolarity? ■ It depends on the amount of solutes in the liquid ○ Listen I am a medical student not a chemistry student please get to the point ■ OK Our plasma has a certain osmolarity. This osmolarity depends on two things: the solutes in the plasma, and the amount of water in it. The major electrolyte in the plasma is sodium.

    © Jones & Bartlett Learning, LLC. NOT FOR SALE OR DISTRIBUTION Chapter 7 Fluid and Electrolyte Management Billie Bartel and Elizabeth Gau L EARNING OBJECTIVES 1. Identify and understand basic fluid and electrolyte abnormalities in critically ill patients. 2. Differentiate between the types of fluids used for fluid replacement in different disease states commonly seen in the intensive care unit. 3. Recognize the causes of electrolyte abnormalities in critically ill patients. 4. Understand when and how to replace or replete electrolytes in critically ill patients. INTRODUCTION Fluid and electrolyte abnormalities are common in critically ill patients and often represent complications from underlying disease states or medication therapies. Critically ill patients often experience alterations in absorption, distribution, and excretion of fluids and electrolytes. Changes in hormonal and homeostatic processes and fluid status are also common in intensive care unit patients. 1 04783_CH07_PASS01.indd 1 11/2/11 3:16:52 PM © Jones & Bartlett Learning, LLC. NOT FOR SALE OR DISTRIBUTION 2 Chapter 7: Fluid and Electrolyte Management Significant complications can result from fluid and electrolyte abnormali- ties, and the severity of these complications usually parallels the magnitude of the disorder. Fluid and electrolyte disorders occurring acutely and rap- idly are often associated with increased symptoms and complications when compared to chronically occurring imbalances; these symptomatic abnor- malities require more urgent treatment. Recognizing the cause of fluid and electrolyte abnormalities is important when making treatment decisions. Critically ill patients often require very frequent monitoring and evaluation of fluid status and serum electrolyte concentrations throughout their treat- ment course. Pharmacists often assist in the management of fluid and electrolyte ab- normalities in the intensive care unit.

  • Fluid and Electrolytes in Adult Parenteral Nutrition by Theresa Fessler, MS, RD, CNSC
    Fluid and Electrolytes in Adult Parenteral Nutrition By Theresa Fessler, MS, RD, CNSC Suggested CDR Learning Codes: 2070, 3040, 5440; Level 3 Body fluid and serum electrolyte concentrations often become imbalanced in patients who require parenteral nutrition (PN) due to one or more factors, such as physiologic stress, wound drainage, blood loss, gastrointestinal fluid loss, organ malfunction, hormonal abnormalities, IV fluid use, various medications, and even unavoidable shortages of parenteral electrolyte products. It’s important to discuss each patient’s clinical status with the physicians, pharmacists, and nurses involved in the patient’s care to become fully informed about his or her clinical situation. With knowledge of fluid and electrolyte requirements, the conditions in which these needs are altered, and the physical signs of excesses or deficits, RDs can determine safe and reasonable adjustments to PN electrolyte content. This continuing education course focuses on the role of fluid and electrolytes in PN and the clinical situations in which water and electrolytes may need to be adjusted in PN. It’s intended for practitioners who have a good basic knowledge of and experience with PN. Part 1: Requirements for Water and Electrolytes and Units of Measurement The Institute of Medicine lists the Dietary Reference Intakes for oral nutrients in milligrams or grams.1 Parenteral and oral requirements are, of course, different because intravenous administration bypasses normal digestion and absorption. For IV fluids and PN, the milliequivalent (mEq) is the unit of measurement used for sodium (Na), chloride (Cl), potassium (K), magnesium (Mg), calcium (Ca), and acetate, while the millimole (mM) or the milliequivalent can be used for phosphorus (P).2,3 Electrolytes are compounds or substances that dissociate in the solution to release positively and negatively charged ions that can carry electric current—thus, the term electrolyte.
