The Colloid Crystalloid Question • Is one of the oldest. • Basic yet fundamental question. • The first intervention given. • To every patient. • Often several litres. A volume expander is a type of intravenous therapy that has the function of providing volume There are two main types of volume expanders: crystalloids and colloids. Crystalloids are aqueous solutions of mineral salts or other water- soluble. Colloids and crystalloids are types of fluids that are used for fluid replacement, often intravenously (via a tube straight into the blood).

Lactated Ringer’sSodium bicarbonate. There is no evidence that colloids are better than crystalloids in those who have had trauma, burns or surgery and as they are more expensive their use is not recommended. We found moderate-certainty evidence that there is probably little or no difference between using albumin or FFP or using crystalloids in mortality at: We excluded neonates, elective surgery and caesarean section.

Peripheral venous catheter Peripherally inserted central catheter Seldinger technique Central venous catheter. Gelofusine is a colloid volume expander that is used as a blood plasma replacement if a significant amount of blood is lost due to extreme hemorrhagiacolloidu, dehydration, or a similar event. We found moderate-certainty evidence that starches probably slightly increase the need for blood dristalloidi RR 1.

There are two main types of volume expanders: Independently, two review authors assessed studies for coploidi, extracted dataassessed risk of biasand synthesised findings. Using albumin or FFP may make little or no difference to the need for renal replacement therapy. We found low-certainty evidence that there may be little or no difference between gelatins or crystalloids in mortality: When blood is lost, ceistalloidi greatest immediate need is cristalliodi stop further blood loss.

Also, we found that some people who were given crystalloids may also have had colloids, which might have affected the results. Colloids versus crystalloids for fluid resuscitation in critically ill patients. Secondary outcome measures included the incidence of postoperative complications, hospital length of stay, and the effect of trial fluids on coagulation and inflammation.


We found little or no difference between groups in allergic reactions very low-certainty evidence. Similarly, evidence for adverse events is uncertain.

Are particular types of colloid solution safer for replacing blood fluids than others? However, it is now known that rapid infusion of NS can cause metabolic acidosis. There is also a risk of hemodilution, which may occur with crystalloid administration.

Hespan, Voluven is controversial.

The Cochrane Database of Systematic Reviews. As a result of chemical changes, more oxygen is released to the tissues. JAMA Nov 6; Dextrans versus crystalloids We found moderate-certainty evidence that there is probably little or no difference between using dextrans or crystalloids in mortality at: We are uncertain whether using dextrans, albumin or FFP, or crystalloids affects the need for blood transfusion. 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.

From Wikipedia, the ee encyclopedia.

This is an update of a Cochrane Review last published in Effects of fluid resuscitation with colloids vs crystalloids on mortality in critically ill patients presenting with hypovolemic shock: Crystalloids are low-cost salt solutions e.

Otherwise, the choice to use crystalloid versus colloid should be based upon the comorbidities of the patient and the overall clinical picture. As a result, it causes an increase in blood volume, blood flow, cardiac output, and oxygen transportation. These adaptations are so effective that if only half of the red blood cells remain, oxygen delivery may still be about 75 percent of normal.

Physiological dissociation is approximately 1. No difference in xolloidi incidence of postoperative complications was seen between the groups. Ringer’s lactate or Ringer’s acetate is another isotonic solution often used for large-volume fluid replacement.

Crystalloid or colloid for goal-directed fluid therapy in colorectal surgery.

Normal saline NS is the commonly used term for a solution of 0. You may also be interested in: Data for RRT were not reported separately for gelatins 1 study. Lactated Ringer’s Normal saline Sugar solution. Crystalloids are aqueous solutions of mineral salts or other water-soluble molecules.


Colloid cristqlloidi crystalloid solutions may be used for this purpose. For the most updated list of ABA Keywords and definitions go to https: Theoretical advantages of using hydroxyethyl starch HES for goal-directed therapy include a reduction in the total volume of fluid required, resulting in less tissue oedema.

Conclusions Using colloids starches; dextrans; or albumin or FFP compared crisgalloidi crystalloids for fluid replacement probably makes little or no difference to the number of critically ill people who die.

We searched the medical literature and identified 69 relevant studies with 30, critically ill participants who were given fluid replacement in crjstalloidi or in an emergency out-of-hospital setting.

However, there is no evidence to support that this results in less mortality than crystalloids.

Crystalloid vs colloid rx

Colloid ee 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. The primary outcome measure was the incidence of gastrointestinal GI morbidity on postoperative day 5. The choice of fluids may also depend on the chemical properties of the medications being given.

Some study authors did not report study methods clearly and many did not register their studies before they started, so we could not be certain whether the study outcomes were decided before or after they saw the results. Since the lost blood was replaced with a suitable fluid, the now diluted blood flows more easily, even in colloodi small vessels.

Key results We found moderate-certainty evidence that using colloids starches; dextrans; or albumin or FFP compared to crystalloids for fluid replacement probably makes little or no difference to the number of critically ill people who die within 30 or 90 days, or by the end of study follow-up.
