Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: crystalloid	Drug: Ringer-lactate "SAD"; Lactated Ringer's is administrated intravenously in the dosis of max. 35 ml/kg during the operation after securing normovolaemia with Nexfin Monitor at induction of the anaesthesia: if bolus infusion of 200 ml increases stroke volume more than 10 % the patient is not assumed normovolaemic and bolus infusions are repeated until normovolaemic status is achieved.; Other Names: Ringer-laktat "SAD", B 05 BB 01, Amgros A/S.
Placebo Comparator: colloid	Drug: HES 130/04; Voluven is administered intravenously in the doses of max. 35 ml/kg during the operation. Normovolaemia is achieved in the same way as described in intervention by Ringer-lactate "SAD".; Other Names: Voluven, HES 130/04, B 05 AA 07, Fresenius Kabi A/S.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Effect of colloid versus crystalloid on laboratory coagulation.	Coagulation is analysed in bloodsamples before, during (10 minutes post cystectomia), at the end of the operation and 2 hours later on. The bloodsamples are analysed by thromboelastography (5000 series TEG analyzer, Haemoscope Corporation, Niles IL, USA) besides the classic coagulation parametres: platelet count, INR, Fibrinogen, APTT, D-dimer and Haemoglobin, Amylase and Creatinin.	5-7 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Effect of colloid versus crystalloid on the amount of bloodloss	The water balance inclusive the amount of bloodloss is registrated at the end of the operation and 2 hours later on.	5-7 hours
