conclusions the results of this meta-analysis show that colloid fluids can increase the successful resuscitation rate compared to crystalloid fluids especially in traumatic and hypovolemic patients.some of the colloids like albumin and dextran have a positive effect on reducing the mortality rate but others like hetastarch (hes) increase the mortality rate compared to normal saline (ns). result...

Janus colloids propelled by light, e.g., thermophoretic particles, offer promising prospects as artificial microswimmers. However, their swimming behavior and its dependence on fluid properties and fluid-colloid interactions remain poorly understood. Here, we investigate the behavior of a thermophoretic Janus colloid in its own temperature gradient using numerical simulations. The dissipative p...

The treatment of dengue shock syndrome (DSS) is a medical emergency. Prompt and vigorous volume replacement therapy is required, with extreme care to avoid fluid overload. Recognition of the importance of increased vascular permeability in the pathophysiology of DSS and of the critical need for parenteral fluids in resuscitation has had a dramatic effect on mortality from the disease over the l...

Colloid osmotic pressures of the body fluids of twenty invertebrate species were measured directly. The results, which are generally lower than predicted values for the same species, pertain to several physiological questions: (1) they do not quantitatively explain the frequently observed hyperosmoticity of body fluids in species believed to be osmoconformers, indicating that the condition cann...

The current trend in anaesthesia is to choose crystalloid over colloid fluids for volume replacement in the operating room. Outcome-oriented studies and kinetic analyses have recently provided more insight into how crystalloid infusions should be managed. These fluids have a much better short-term effect on the plasma volume than previously believed. Their efficiency (i.e. the plasma volume exp...

PURPOSE OF REVIEW To highlight some of the recent key issues surrounding crystalloid and colloid fluid management of critically ill patients. RECENT FINDINGS Significant developments have been made in the understanding of ionic balance of fluids and their effects on acid-base, the role of hydration and overhydration, alkalinization of fluids in patients at high risk for contrast induced nephr...

In the subsequent 20-min interval after intra-aortic injection of these test solutions, capillary protein concentration remained at (isoncotic infusions) or returned to (colloid-free and hyperoncotic fluids) control values. Whereas reabsorption after colloid-free solutions returned to base line levels in parallel with the return in capillary protein concentration, after colloid infusions (which...

Polymer chains in colloid-polymer mixtures can be coarse-grained by replacing them with single soft particles interacting via effective polymer-polymer and polymer-colloid pair potentials. Here we describe in detail how Ornstein-Zernike inversion techniques, originally developed for atomic and molecular fluids, can be generalized to complex fluids and used to derive effective potentials from co...

Fluids available for intravenous volume replacement may be either crystalloid or colloid. The fundamental differences between these fluids are their effects on the Starling equation (table 1) which describes fluid flux between the intravascular and interstitial spaces. Starling stated that the rate of fluid movement into or out of a capillary is related to the net hydrostatic pressure minus the...
