SYNTHETIC VOLUME EXPANDERS

Question 1

What are some examples of synthetic volume expanders categorized under crystalloids and colloids?

Answer 1

Crystalloids:
- NSS (Normal Saline Solution)
- Ringer’s lactate
- Electrolyte Solution

Colloids:
- Dextran
- Hydroxyethyl starch (HES)

Question 2

What are the components of the given crystalloid and colloid solutions?

Answer 2

• The crystalloid solution consists of Ringer’s solution and 7.5% normal saline.
• The colloid solution is composed of dextran, albumin, and hydroxylethyl starch.

Question 3

What are the characteristics of crystalloids?

Answer 3

• Crystalloids have poor IV retention, commonly cause peripheral edema,
• Might lead to pulmonary edema, are easily excreted, have no allergic reactions, and are relatively inexpensive.

Question 4

What are the characteristics of colloids?

Answer 4

• Colloids IV can lead to good retentions, with a possibility of peripheral edema and pulmonary edema.
• They are not easily excreted and allergic reactions are rare, though they are more expensive.
