2. Lactated Ringer's

2

Isotonic Mechanism of Action

No Fluid Shift

3

Isotonic Tx

1. Fluid loss (Dehydration) Due to:
a. vomiting
b. diarrhea
c. surgical procedure-when BP is low

4

Isotonic Adverse Effects

1. Fluid overload

5

Isotonic Implication

1. Watch for signs of fluid overload

c. Distended neck veins
d. Dyspnea
c. Cough

6

Hypertonic Fluid Name

1. 3% NaCl
2. 5% Dextrose in NS

7

Hypertonic Mechanism of Action

1. Water moves from cells & Interstitial space to plasma volume

8

16

Colloids Mechanism of Action

1. Replaces fluid
2. Promotes excretion through urine (hypertonicsolution-water from cells to plasma)
3. Contains electrolytes
4. Molecules too large to pass through capillary membranes
5. Increase osmotic pressure

17

2. Monitor I&O's

21

Crystalloids Fluid Names

1. Normal Saline (0.9%)
2. Hypertonic Saline (3%)
3. Hypotonic Saline (0.45%)

22

Crystalloids Mechanism of Action

1. Expands plasma volume
2. Draws water from intercellular & interstitial space to the plasma
3. Mostly Na+ but can contain dextrose

23

Crystalloids Tx

1. Fluid loss due to:
a. Vomiting
b. Diahrrea
c. Surgical procedures
2. Hypertonic solutions Tx cellular edema & cerebral edema
3. Hypotonic solutions Tx hypernatremia & cellular dehydration
