Radical Prostatectomy and Perioperative Fluid Therapy

Radical Prostatectomy and Perioperative Fluid Therapy

The optimal amount of fluid a patient need under surgery is not clear. Both to much and to little fluid can damage the organ functions.

A strategy called "Goal directed therapy", where the fluid amount a patient need is guided by the stroke volume, has shown to minimize post-operative nausea and vomiting.

The investigators intend to investigate if patients treated after these standards, has a better outcome then patients treated after normal regimes, regarding post-operative orthostatic-intolerance.
