The study shall evaluate the volume effect and safety of 6 % hydroxyethyl starch 130/0.4 for restoration and maintenance of hemodynamics during the investigational period in patients undergoing major elective surgery. Up to 50 mL 6% hydroxyethyl starch/kg body weight will be administered from start of surgery until two hours after end of surgery. The study hypothesis is that 6 % hydroxyethyl starch 130/0.4 will have a reliable volume effect and can be safely administered up to the dose limit.

The study shall evaluate the efficacy and safety of two different hydroxyethyl starch solutions (artificial colloids 6% HES130/0.4 and 6% HES70/0.5, Salinhes®) for intra-operative therapy of hypovolemia and maintenance of circulating blood volume in patients undergoing orthopedic surgery. The primary efficacy endpoint will be the required volume of colloid solution infused from start until end of surgery. It is the aim of the clinical trial to demonstrate that comparable volumes of colloid solution are used between treatment groups.
