Answer 2

Answer:

Colloids Examples

Colloids are the type on intravenous fluids with high osmolarity that are ideal to transfuse in conditions like decreased intravascular volume. A Few Colloids Examples are:

1. Dextrans (Lomodex)
2. Albumins
3. Gelatins (Haemaccel)
4. Hydroxyethyl Starch
5. Perflurocarbon Emulsions

Explanation:

1. Dextrans (Lomodex) :

For more on Dextrans read

2. Albumins : Available as 5% and 25% solution.

These are very expensive.

Albumin has an intravascular half life of 10-15 days.

Used when there is protein loss from body like in:

Peritonitis.

Liver failure.

Burns.

Protein losing enteropathies.

3. Gelatins (Haemaccel) : Colloids Examples that is most commonly used are the gelatins. They have a Molecular weight of 30,000. They are available as 3.5% solution.

Composition of Haemaccel: Each liter contains:

Gelatin : 35g

Sodium : 145 mEq

Chloride : 145 mEq

Potassium : 5 mEq

Calcium : 12 mEq

Expand plasma effectively for 2 hours (25% may be present in blood after 12 hours).

At clinically used doses these do not interfere with blood grouping, platelet function & clotting but at high doses they can also interfere with clotting. Incidence of severe anaphylactic reactions is very less.

As haemaccel contains high calcium therefore citrated blood should not be mixed.

4. Hydroxyethyl Starch : These are newer Colloids .

Examples. Two kind of hydroxyethyl starches are available – Hexastarch and Pentastarch.

Available as 6% and 10% solution. They have prolonged half life and expand plasma effectively for 4 hours.

These solutions improve microcirculation and hence improve oxygen delivery to tissues.

5. Perflurocabon Emulsions : (See section of substitute blood).
