Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Changes in cardiac output, blood pressure and pulse as well as measurements in plasma of albumine and kreatinin. Fluidcomposition and balance preoperative and one day after surgery.;Timepoint(s) of evaluation of this end point: Preoperative, after surgery and at the first postoperative day | — |
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Does a fluid challenge give an increase in plasmavolume, measured as a dilution of the red blood cells, during bariatric surgery? Does acetated Ringers give a similar plasmavolume increase as albumin solutions both in size and in length?;Secondary Objective: Is there a correlation between volume effect and circulatory effects, such as blood pressure and cardiac output? Does "fluid challenge" with acetated Ringers resilt in a clinical relevant effect (plasma volume and cardiac output) on the longer run? In the perspective of 24 hours, does the choise of fluid have any importance for the fluid balance of the body? How are kidney function markers and arterial blood gases influenced by the three different fluid therapies?;Primary end point(s): Decrease of hemoglobine concentration when a fluid challenge is adminstered. The decrease is processed mathematically in a kinetic model.;Timepoint(s) of evaluation of this end point: Before, during and up to 60 minutes after the fluid challenge. Timepoints to be statiscaly evaluated are before and after the infusion as well as 30 minutes after end of the infusion. | — |
