Study hypothesis
To assess whether post-operative Goal Directed Therapy results in improved clinical outcomes through enhanced tissue perfusion and oxygenation.
Please note that as of 23/10/2007 this application was amended. The amendment will allow us to compare the effects on tissue perfusion and oxygenation of post-operative Goal Directed Therapy with intravenous fluid alone and that of Goal Directed Therapy with fluid plus dopexamine. All changes relating to these amendments will be noted under the date '23/10/2007'. These amendments have included the addition of two funders, a change to the target number of participants (as of 17/04/2007 this was updated to 80, and was originally entered as 120), a change to the anticipated start date (this was originally 01/12/2006) and an addition to the interventions.
Ethics approval
Approved by the London Multi-Centre Research Ethics Committee on the 17th November 2006 (ref: 06/MRE02/70).

Condition
Major abdominal surgery
Intervention
In addition to maintenance fluid, control group patients will receive additional 250 ml fluid challenges with colloid solution as required, to achieve a sustained rise in central venous pressure.
In addition to maintenance fluid, intervention group patients will receive additional 250 ml fluid challenges with colloid solution as required, to achieve a sustained rise in stroke volume. Patients in the intervention group will also receive dopexamine at a fixed rate of 0.5 mcg/kg/min.
As of 17/04/2007:
Due to funding problems we will only be able to recruit enough patients for our secondary outcome measure therefore only 80 participants are expected to be recruited.
As of 23/10/2007:
A second intervention group will receive, in addition to maintenance fluid, additional 250 ml fluid challenges with colloid solution as required, to achieve a sustained rise in stroke volume but this will not be supplemented with dopexamine.
