What are the indications of Crystalloids?

Crystalloid fluids are the first choice for fluid resuscitation in the presence of hypovolemia, hemorrhage, sepsis, and dehydration.

What are Crystalloids and colloids used for?

Colloids and crystalloids are types of fluids that are used for fluid replacement, often intravenously (via a tube straight into the blood).

When do you use Crystalloids and colloids?

Crystalloid solutions are used to treat most patients with shock from dengue, while colloids are reserved for patients with profound or refractory shock.

What is the difference between crystalloid and colloid solutions?

Colloids are those substances which are not easily crystallized from their aqueous solutions. Crystalloids are those substances which are easily crystallized from their aqueous solution. Colloids contain much larger particles than crystalloids (1 – 200 nm).

What are the advantages and disadvantages of Crystalloids?

Crystalloid therapy may, however, adversely affect microcirculatory blood flow and oxygenation when used in cases of shock, resulting in hypoxia even after resuscitation (Krau, 1998). The main disadvantage of using a crystalloid fluid is that excessive use will cause peripheral and pulmonary oedema (Bradley, 2001).

What are colloids used for?

Colloids and crystalloids are types of fluids that are used for fluid replacement, often intravenously (via a tube straight into the blood). Crystalloids are low-cost salt solutions (e.g. saline) with small molecules, which can move around easily when injected into the body.

Why are colloids used in medicine?

Colloids are used to provide oncotic expansion of plasma volume. They expand plasma volume to a greater degree than isotonic crystalloids and reduce the tendency of pulmonary and cerebral edema. About 50% of the administered colloid stays intravascular.

What are the advantages to administering colloids over Crystalloids?

Colloids are better than crystalloids at expanding the circulatory volume, because their larger molecules are retained more easily in the intravascular space (Kwan et al, 2003) and increase osmotic pressure (Bradley, 2001).

What are colloids used for in nursing?

Which fluid to administer? Crystalloids and colloids are plasma volume expanders used to increase a depleted circulating volume. Over the years they have been used separately or together to manage haemodynamic instability.

Can a colloid be used for fluid replacement?

Colloid or crystalloid solutions may be used for this purpose. Crystalloids have small molecules, are cheap, easy to use, and provide immediate fluid resuscitation, but may increase oedema.

What are the risks of excessive use of colloids?

However, excessive use of colloids can precipitate cardiac failure, and pulmonary and peripheral oedema (O’Neill, 2001). Although the pulmonary oedema caused by excessive use of colloids is delayed in comparison with that caused by crystalloids, it is more sustained (Bradley, 2001).

What are the disadvantages of using crystalloid fluid?

The main disadvantage of using a crystalloid fluid is that excessive use will cause peripheral and pulmonary oedema (Bradley, 2001). Dextran. There has been criticism of research, however, because tests involved a single colloid type only but the conclusions drawn were applied to the whole classification of colloids (Krau, 1998).

Which is better, a colloid or a crystalloid?

Colloids, on the other hand, may (rarely) trigger an anaphylactic reaction. While low dose colloids typically preserve hematocrit and coagulation factor levels, there is a risk of abnormal hemostasis occurring if too much colloid is administered, especially synthetic colloids. Of note crystalloids are significantly cheaper than colloids.
