BACKGROUND In the past, several studies have compared different colloidal replacement solutions, whereby the focus was usually on the respective colloid. We therefore systematically studied the influence of the carrier solution's composition of five approved colloidal volume replacement solutions (Gelafundin, Gelafusal, Geloplasma, Voluven and Volulyte) on acid-base as well as electrolyte statu...

A conceptual model for colloid transport is developed that accounts for colloid attachment straining, and exclusion. Colloid attachment and detachment is modeled using first-order rate expressions, whereas straining is described using an irreversible first-order straining term that is depth dependent. Exclusion is modeled by adjusting transport parameters for colloid-accessible pore space. Fitt...

Hydroxyethyl starch (HES) solutions are synthetic non-protein colloid solutions used to treat hypovolemia. However, their use is not free from the risk of allergic reactions. A 42-year-old male was scheduled to undergo aortic-iliac-femoral bypass surgery for the treatment of arteriosclerosis obliterans. He had no history of allergy. Two hours after the start of surgery, and within minutes after...

Absorption and extinction spectra of fractal and nonfractal small-particle composites are studied. General solutions of the coupled-dipole equations with the exact operator for the dipole interaction ~including the near-, intermediate-, and far-zone terms! are found and compared with those in the quasistatic approximation. Broadscale numerical simulations of optical spectra for clusters contain...

Aims and Background: Considering the importance of postoperative hyperlactatemia, rehydration impact on lactate amount, and different challenges in using crystalloid and colloid solutions for rehydration, we decided to investigate the effect of Ringer solution and Hemaxel on blood lactate level with comparing the changes before and after the operation, in patients undergoing appendectomy. ...
