Coloides versus cristaloides para la reanimación con líquidos en pacientes en estado crítico. Perel P, Roberts I Reproducción de una revisión Cochrane. The ALBIOS study (NCT) comparing the use of albumin versus crystalloid has stopped recruiting patients. Their results have not been published, but. 1. Definición de Soluciones. 2.

This year, the people of North Carolina have a chance to guarantee their. However, special modifications to the kext file must coloides vs cristaloides made to enable Core Image and Quartz Extreme.
The principal modifications introduced by these solutions are a reduction of the concentrations of sodium and particularly chloride, replacing the latter anion with lactate Ringer lactate or acetate, malate or gluconate new balanced solutions. The pH of these formulations is less acidic than in the case of saline solution, and their sodium and chloride concentrations are more similar to those of plasma.
The volume expanding effect achieved with these solutions is very similar coloides vs cristaloides that of saline solution. It must be noted that plain Ringer solution cannot be regarded coloides vs cristaloides a balanced solution due to its sodium and chloride contents, which are very similar to those of saline solution Table 1.

The most widely used formulation is Ringer lactate or Hartmann's solution, which is slightly hypoosmolar with respect to plasma Table 1 and contains 28mEq of lactate per liter, which is transformed into pyruvate and posteriorly to bicarbonate in the course of its metabolism as part of the Cori cycle.
This amount of lactate is present as a mixture of d-lactate and l-lactate. Of these two forms, l-lactate is the most coloides vs cristaloides, and is metabolized by lactate dehydrogenase, while d-lactate is metabolized by d-a-dehydrogenase.
Ringer acetate is currently not marketed in Spain.
They produce faster and more persistent hemodynamic effects than crystalloids, and require less administered volume than the latter. Colloids in turn are either synthetic gelatins, starches and dextrans or natural albumin. Dextrans Dextrans are mixtures of glucose polymers that are available in two solutions: These formulations are coloides vs cristaloides to a considerable incidence of side effects such as allergic reactions, renal failure or bleeding disorders, and are practically no longer used.

These two formulations differ not only in their chemical characteristics but also in their expansion capacity, electrolyte composition and adverse effects. Hydroxyethyl starch Hydroxyethyl starch HES is composed of modified natural polysaccharides obtained from corn or potato starch by replacing the hydroxyl groups with coloides vs cristaloides ether groups in the glucose molecules of amylopectin.
As the project develops, new journal titles are being added in the library collection. A bibliographic research was carried out in Medline, Pubmed, Embase and Cochrane Library, corroborating randomized clinical trials in those crystalloids coloides vs cristaloides compared to colloids in GDFT for mayor non-cardiac surgery in adults.
They are classified according to the mean molecular weight range: This substitution increases the solubility of starch in water and, to a coloides vs cristaloides degree, inhibits the rate of degradation of the starch polymer by amylases.
The half-life of a starch solution depends on its molecular weight, degree of substitution, and the proportion of hydroxyethyl groups in the C2 carbon when compared with the C6 carbon of the glucose monomer.
Hence, they could be used to treat critically ill patients.

Nonetheless, this hypothesis was not confirmed in the most recent clinical trials. Albumin Albumin solutions are used worldwide to treat critically ill patients.
A meta-analysis carried out in associated albumin usage to coloides vs cristaloides mortality rate. Actually, it could be noticed that some subpopulations, such as those with traumatic brain injury, can have an increased risk of death when receiving albumin solutions.
