Aim: Aim: IInvestigate the role of hydroxyethyl starch (HES) 130/0.4 on the wound healing process in left colonic anastomoses in the presence of intra-abdominal sepsis
Results: MResults: Moderate doses (15 mL/kg) of HES 130/0.4 administration significantly prevented this intraperitoneal sepsis-induced impaired anastomotic healing of the left colon. This beneficial effect of HES 130/0.4 can be mainly attributed to its anti-yinflammatory and antioxidant properties and beneficial effects of modulating endothelial-associated coagulopathy.

h d th l t h (HES) tihydroxyethylstarch (HES) preparations.
METHODS: Blood from 12 healthy young male volunteers was diluted by 10, 30 and 50% byBlood from 12 healthy young male volunteers was diluted by 10, 30 and 50% by
using either a balanced 6% HES 130/0.42 or a nonbalanced 6% HES 130/0.4.
Rotation thrombelastometry was used to assess changes in coagulation
RESULTS: extreme haemodilution with HES 130/0.42 dissolved in a balanced solution
containing calcium was associated with less negative effects on thrombelastometry and platelet aggregation than HES 130/0.4 prepared in a nonbalanced solution without calcium. Gelatin prepared in a nonbalanced solution showed similar effects on coagulation to balanced HES without calcium.
