3 Different types of colloids and crystalloids, as described in this slide, are currently available for fluid therapy. There is currently a wide variation in the types and amount of fluids used throughout the world. Common perceptions are that the Americans appear to use albumin more than Europeans, Scandinavians use Ringer’s acetate more than other Europeans, the Germans use a lot of hydroxyethyl starch dissolved in saline and the English prefer to use gelatin. Nobody understands the reasons for these differences, and they just make the situation very confusing. One of the aims of the FORTE programme is to put the science back into fluids and to try and understand the real differences between the different types of fluids, and determine the best solution for different situations, to come to an optimised solution. .

Fluids were administered perioperatively and continued for 24 h on the intensive care unit to keep central venous pressure between 8 and 12 mmHg. As shown in the table, patients who were treated only with a crystalloid received more fluid that those treated with a colloid + crystalloid. Urine output was significantly larger in the crystalloid group than in the HES-treated patients. As shown in the figure, tissue oxygen tensions increased significantly in HES-treated patients (a maximum of 59% at T4), but decreased significantly in the RL-treated group (a maximum of -23% at T4). The highest differences between the two groups were seen on the morning of the first post-operative day (T4). In conclusion, not only are colloids effective in maintaining volume, but significantly less fluid is required (compared with crystalloid therapy alone), meaning less haemodilution and better maintained tissue oxygenation.

19 Farmakokinetyka roztworów HES 130/0,42 i HES 200/0,5 po kolejnych podaniach u zdrowych ochotników
Dawka dzienna – 50 g Hydroxyethyl starches can accumulate in the circulation when administered repeatedly. Such accumulation is thought to be partly responsible for undesirable effects such as tissue storage and blood coagulation impairment. In this study in healthy volunteers, the pharmacokinetics of HES 130/0.42/6:1 were investigated using a crossover design with HES 200/0.5 serving as control. HES (50 g of each type) was administered in 4 h day 21 for a period of five consecutive days. HES serum concentrations were used for computation of pharmacokinetic coefficients. The circulation was freed from the load with HES 130/0.42 within 20 h after end of the previous infusion, while the amount of HES 200/0.5 increased continuously from one administration to the other. Elimination half-life (shown on the slide) was significantly lower with HES 130/0.42. Repeated administration of a low molecular weight starch (HES 130/0.42 vs HES 200/0.5) showed no accumulation and fewer tendencies to time-dependent changes in pharmacokinetic parameters. 130 kDa is the ideal size of starch for optimal microcirculation function.
