- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* patients undergoing the following elective major abdominal surgery: oesophagectomy, total gastrectomy, radical cystectomy, aorta-bifemoral bypass or elective operation of abdominal aortic aneurysm.~* after surgery patients were admitted to our intensive care unit.~Exclusion Criteria:~* patients younger than 18 years~* chronic organ insufficiency: Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system: New York Heart Association Class IV, chronic hypoxia or hypercapnia, chronic renal failure requiring renal replacement therapy, biopsy proven cirrhosis or portal hypertension and immunodeficiency.~* preoperative anaemia (haemoglobin\<100g/L)~* coagulation abnormality~* and patients with chronic use of corticosteroids and non-steroid anti-inflammatory drugs~* patients requiring an operation due to malignant disease where the tumour then proved to be inoperable.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Control (Type: ACTIVE_COMPARATOR): In the control group if the mean arterial pressure fall below 60 mm Hg and the central venous pressure (CVP) is low fluid bolus is administered if the central venous pressure is in normal range vasopressor is given.
- CeVOX (Type: EXPERIMENTAL): In the ScvO2 group patients receive interventions in two options: if the ScvO2 fall below 75% or more than 3% or if the mean arterial pressure fall below 60 mm Hg. In the former case the mean arterial pressure in the latter the ScvO2 values determined if tha patient received fluid or vasopressor or both.

Based on this trial design, predict the completion outcome and termination type (if applicable).
