1

explain the fluid compartment

  • intracellular fluid > 40%
  • extracellular fluid > 20%
  • interstitial > 15%
  • intravascular > 5%

2

fluid requirements

card image

3

fluid restriction

20-25 ml/kg/day

4

factors affecting fluid requirements

  • fever
  • sweating
  • hyperventilation
  • hyperthyroidism

5

isotonic dehydration

electrolytes = fluid

no fluid movement

6

hypotonic dehydration

electrolytes > fluids

extracellular ( low electrolytes ) to intracellular (higher)

7

hypertonic dehydration

electrolytes < fluids

intracellular ( lower) to extracellular (higher)

8

hypovolemic hyponatremia management

  • underlying cause
  • volume repletion > NS or hypertonic
  • replace Na

9

hypervolemic hyponatremia management

  • underlying cause
  • diuretics
  • fluid restriction > concentrated formula, no flushing > 1L
  • remove Na from IV & PN

10

Euvolemic hyponatremia management

  • underlying cause
  • fluid restriction
  • Na replacement

11

Euvolemic hypernatremia management

  • hypotonic solution
  • remove Na from PN
  • bolus water in EN

12

hypovolemic hypernatremia management

  • Water replacement + Na replacement = NS
  • hypotonic > after volume correction

13

hypervolemic hypernatremia management

  • cause > hypertonic
  • fluid restriction
  • Na elimination
  • concentrated formula

14

moderate hypernatremia level and ttt duration

  • 150-169
  • 48 hrs

15

sever hypernatremia level and ttt duration

  • >170
  • 96 hrs

16

hypokalemia management

  • 40 - 60 meq/day
  • wait 2 hrs then k+ lab test

17

hypokalemia management

  1. Ca gluconate or Na gluconate > intracellular shift
  2. insulin + 50% dextrose
  3. dialysis

18

Cl roles

  • extracellular
  • acid base balance
  • correct acidosis
  • blood volume
  • blood pressure
