Why would you give a specific crystalloid or colloid?

Why would you give a specific crystalloid or colloid?

Crystalloids have small molecules, are cheap, easy to use, and provide immediate fluid resuscitation, but may increase oedema. Colloids have larger molecules, cost more, and may provide swifter volume expansion in the intravascular space, but may induce allergic reactions, blood clotting disorders, and kidney failure.

When would you use colloids over Crystalloids?

There are two types of IVFs, crystalloid and colloid solutions. Crystalloid solutions are used to treat most patients with shock from dengue, while colloids are reserved for patients with profound or refractory shock.

Why would you give a colloid?

Colloids are gelatinous solutions that maintain a high osmotic pressure in the blood. Particles in the colloids are too large to pass semi-permeable membranes such as capillary membranes, so colloids stay in the intravascular spaces longer than crystalloids.

What are crystalloid and colloid fluids?

Crystalloids fluids such as normal saline typically have a balanced electrolyte composition and expand total extracellular volume. Colloid solutions (broadly partitioned into synthetic fluids such as hetastarch and natural such as albumin) exert a high oncotic pressure and thus expand volume via oncotic drag.

What should you know about crystalloids and colloids?

Guide to Crystalloids and Colloids 1 Keeps fluid in vessels 2 Maintains volume 3 Used to replace protein and treat shock and erythroblastosis fetalis 4 May cause anaphylaxis (watch for hives, fever, chills, headache). 5 May cause fluid overload and pulmonary edema

When to use crystalloid fluid in a clinical setting?

Crystalloid fluids are a subset of intravenous solutions that are frequently used in the clinical setting. Crystalloid fluids are the first choice for fluid resuscitation in the presence of hypovolemia, hemorrhage, sepsis, and dehydration.

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.

Who is at risk for crystalloid fluid overload?

Volume expansion with crystalloid fluids may cause iatrogenic fluid overload. The risk of this complication becomes particularly elevated in patients with impaired kidney function (acute kidney injury, chronic kidney disease, etc.), and these patients should, therefore, receive treatment with judicious use of intravenous fluids.
