BACKGROUND AND PURPOSE We evaluated isovolumic hemodilution with hydroxyethyl starch 200/0.5 in a rat model of focal cerebral ischemia. This compound avoids the unfavorable viscosity and erythrocyte aggregation abnormalities of low molecular weight dextran during administration over a period of several days. METHODS Sprague-Dawley rats, anesthetized with 0.5-1% halothane and 70% N2O, were sub...

The objective of this study was to evaluate the effects of hydroxyethyl starch, (130/0.4) 6%, compared to Ringer's acetate and modified gelatin on hypoxemia, inflammatory response, and oxidative stress in an experimental model of acute lung injury (ALI). The ALI/Adult Respiratory Distress Syndrome (ARDS) experimental model was produced by a bronchoalveolar saline lavage. Mature New Zealand whit...

BACKGROUND Plasma expanders are commonly used in the management of critically ill patients, which may exhibit altered hemorheology. We evaluated the effects of various synthetic colloids and Lactated Ringer's (LR) solution on hemorheological parameters in vitro and in a rodent hemorrhagic shock model. METHODS For the in vitro experiments, rat blood was incubated with hydroxyethyl starch (HES)...

HYPOTHESIS Safety differences exist among colloids widely used for fluid management in acutely ill patients, as judged according to the comparative incidence of adverse events. DATA SOURCES Colloid safety data for human subjects were sought, without language or time period restrictions, by means of computer searches of bibliographic and clinical trial databases, hand searches of medical journ...

The Scandinavian Starch for Severe Sepsis / Septic Shock (6S) trial showed that hydroxyethyl starch was harmful compared to Ringer's acetate in patients with severe sepsis when used according to clinical practice and in alignment with the recommendations by the manufactures and authorities. The different interpretation by Chapell and Jacob's rely on misreading of the trial publication and is no...

In this work, starch acetate and propanoate derivatives with moderate degree of substitution were synthesized and characterized for employment as matrix formers for sustained release from tablets. Matrix tablets were prepared from cospray-dried and simple physical mixtures of starch/starch derivatives and theophylline as a model drug. The release was rapid for matrix tablets prepared from simpl...
