Fluid And Electrolytes Burns G.U. 2

  1. 1. Irene M. Magbanua, RN Clinical Instructor St. Paul University Manila FLUID AND ELECTROLYTE BALANCE
  2. 2. DEFINITIONS OF TERMS: <ul><li>Intracellular - within cells </li></ul><ul><li>Extracellular – outside cells </li></ul><ul><li>Interstitial – within/between cells </li></ul><ul><li>Intravascular- in the plasma </li></ul><ul><li>Osmoreceptors – specialized neurons that sense the concentration of substances in blood </li></ul>
  3. 3. <ul><li>Baroreceptors – stretch receptors in the aortic arch and carotid sinus that signals the brain to release ADH when blood volume decreases, systolic BP falls or the right atrium is underfilled </li></ul><ul><li>Renin-Angiotensin-Aldosterone-System (RAAS) – a chain of chemicals released to increase both BP and blood volume. </li></ul><ul><li>Osmosis – movement of water through a semi-permeable membrane from a dilute area to a more concentrated area </li></ul>
  4. 4. <ul><li>Osmotic pressure – the power to draw water from an area of greater concentration </li></ul><ul><li>Colloids – large-sized substances such as plasma proteins. </li></ul><ul><li>Colloidal osmotic pressure – subtance that contributes to fluid concentration and acts as force to attract water. </li></ul><ul><li>Filtration – promotes the movement of fluid and some dissolved substances through a semi-permeable membrane according to pressure differences </li></ul>
  5. 5. <ul><li>Passive diffusion – physiologic process by which dissolved substances (ex. electrolyte) move from an area of high concentration to an area of lower concentration thru a semipermeable membrane </li></ul><ul><li>Active transport – requires an energy source, called adenosine triphosphate (ATP) to drive dissolved chemicals from an area of low concentration to an area of higher concentration </li></ul>
  6. 6. <ul><li>Fluid imbalance – general term describing any of severalconditions in which the body’s water in not in the proper volume or location </li></ul><ul><li>Skin tenting – skin that remains elevated and slow to return to underlying tissues (dehydration) </li></ul><ul><li>Pitting edema – indentations in the skin after compression (3L excess in the IVC volume) </li></ul>
  7. 7. <ul><li>Third spacing- translocation of fluid from the IVC or intercellular space to tissue compatrment where it becomes trapped and useless. </li></ul><ul><li>Brawny edema – generalized edema in all the interstitial spaces </li></ul><ul><li>Circumoral paresthesia – tingling around the area of the mouth </li></ul><ul><li>tetany- - muscle twitching </li></ul>
  8. 8. Fluid compartments <ul><li>Intracellular fluid (ICF) – 70% </li></ul><ul><li>Extracellular fluid (ECF) – 30% </li></ul><ul><li>a. Interstitial fluid – 25% </li></ul><ul><li>b. Intravascular fluid – 5% </li></ul><ul><li>c. Transcellular fluid – digestive juices, water and solutes in the renal tubules and bladder, pleural fluid, CSF </li></ul>

  11. 11. Fluid Transport Between Vascular and Interstitial Spaces <ul><li>Fluids move between compartments to maintain homeostasis. Change in pressure promote fluid movement and this takes place across the capillary walls. </li></ul><ul><li>Forces that move fluids are constantly at work and allow the fluid to be taken in orally to maintain BP and hydrate cells and eventually excreted as urine </li></ul>
  12. 12. <ul><li>Blood moves thru the vascular system from an area of higher pressure (arteries) to areas of lower pressure (capillaries and veins) via hydrostatic pressure </li></ul><ul><li>Electrolytes – chemical compounds in solution that have the ability to conduct electric current </li></ul><ul><li>Acids – substances that release hydrogen into fluid </li></ul><ul><li>Bases – substances that binds with hydrogen </li></ul>

  69. 70. Stages of CRF: 1. Renal impairment 2. Renal insufficiency 3. Renal failure 4. End stage of Renal disease
  70. 71. Nursing Management: 1. Conservative- assess uremia, mental function and supportive; avoid undue fatigue 2. Advanced renal failure- oliguric or uremic phase a. peritoneal dialysis b. hemodialysis c. kidney transplant 3. Dietary- early- no restriction - advanced- low protein Giordano or Giovanette diet- low protein with amino acids
  71. 72. Dialysis- removal by artificial means of metabolic wastes, excess electrolytes and excess fluids Principles: -Diffusion, Osmosis, Ultrafiltration Purposes: 1. To remove excessive amounts of drugs or toxins in poisoning 2. To check serious electrolyte or acid base imbalance 3. To maintain kidney function when renal shutdown occurs 4. To temporarily replace kidney function in patients with acute renal failure and permanently replace in chronic renal failure
  72. 73. Peritoneal Dialysis- introduction of specially prepared dialysate solution into the abdominal cavity where the peritonem acts as a semipermeable membrane between the dialysate and blood in the abdominal vessels Nursing Interventions: a. weight, VS every 15 mins then every hour b. Patient voids c. Warm dialysate solution to body temperature d. Assist in trocar insertion e. Inflow time, Dwell time and Drain time f. Observe character of dialysate flow

  75. 76. Nursing Interventions: 1. Auscultate for bruit and palpate thrill- check patency 2. Check bleeding 3. Observe arm precaution 4. Avoid restrictive clothing or dressings over site Complications: 1. Hypovolemic Shock 2. Dialysis disequilibrium syndrome
  76. 77. Renal transplant pre-requisites 1. Evaluation of patient’s medical immunologic, psychological and social status 2. Should be identical- ABO and HLA compatible Contraindications: 1. Acute infection 2. Malignancy 3. COPD 4. Liver disorder 5. DM 6. Atherosclerosis
  77. 78. Pre-op care: 1. Dialysis to make patient non-toxic 2. Treat all complications 3. Immunosuppressive drug to start 24hrs before transplant; immuran, prednisone, sandimmune 4. Transplanted kidney placed on thigh, usually iliac fossa
  78. 79. Post-op care: 1. Reverse isolation 2. Monitor renal functions 3. Respiratory, therapy, deep breathing and coughing exercises 4. Aseptic wound care 5. Oral hygiene 6.NGT to prevent paralytic ileus 7. Early ambulation 8. Health adjustment process 9. Lifetime-immune suppressive drugs
