FLUIDS ARE A CORE ELEMENT IN the resuscitation of critically ill patients and the relative superiority and safety of different resuscitation solutions has been the focus of considerable debate. Crystalloid solutions are inexpensive and readily available, while colloid solutions may minimize resuscitation volumes, and may sustain intravascular volume for longer durations. Conflicting results fro...

BACKGROUND In the present randomized study, we evaluated the differential effects of a colloid and a crystalloid fluid on renal oxygen delivery (RD(O2)), glomerular filtration (GFR), renal oxygen consumption ((RV(O2))), and the renal oxygen supply-demand relationship (i.e., renal oxygenation) after cardiac surgery with cardiopulmonary bypass. METHODS Thirty patients with normal preoperative r...

The behavior of confined colloidal suspensions with attractive interparticle interactions is critical to the rational design of materials for directed assembly(1-3), drug delivery(4), improved hydrocarbon recovery(5-7), and flowable electrodes for energy storage(8). Suspensions containing fluorescent colloids and non-adsorbing polymers are appealing model systems, as the ratio of the polymer ra...

background:: hypercoagulability has been reported in primary brain tumors which can lead to thrombotic complications.hydroxyethyl starch (hetastarch) is a synthetic colloid solution with adverse effects on blood coagulation. the aim of this study was to evaluate the protective effect of hetastarch in reducing thromboembolic events in these patients. materials and methods: in a double-blinded cl...

Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using Confocal Scanning Laser Microscopy we measured the location of each colloid in three dimensions. We observed an equilibrium body-centered tetragonal phase and several non-equilibrium str...

In this article I will review some recent studies of the phase behavior and of the self-assembly of patchy colloidal particles. These studies have been based on simple primitive models for colloid–colloid interactions, effectively extending to soft matter the seminal work of I. Nezbeda on associated fluids. I will discuss the possibilities offered by the study of the self-assembly of particles ...

The debate about whether to use crystalloids or colloids for the resuscitation of hypovolaemia is not as important as the challenge of continually maintaining a normal intravascular volume. In this article we will discuss hypovolaemia and its consequences, the physiology of body fluids and finally the choice of the most appropriate fluid, touching on the colloid-crystalloid controversy.

Submitted for the MAR12 Meeting of The American Physical Society Diffusion in Dense Inhomogeneous Colloid Suspensions in Narrow Channels BINHUA LIN, EMILY WONDER, STUART A. RICE, Univ. of Chicago — We report the results of a study of single particle diffusion in dense colloid fluids confined in a ribbon channel geometry that is intermediate between quasi-one-dimensional (q1D) and quasi-two-dime...

Plasma volume expanders--crystalloid, colloid, or a mixture of both--are used as fluid replacement in patients who have postoperative hypovoloaemia. Despite numerous clinical trials there is little evidence that either classification of plasma volume expander is more beneficial to mortality than the other.
