Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The fluid optimisation group will have an oesophageal doppler inserted after induction. A maintenance rate of Hartmann's solution at 6mls/kg/hr will run intravenously at the start to the end of the operative period. The anaesthetist will use the oesophageal doppler to administer colloid boluses intravenously (250mls Hydroxyethyl starch 130/0.4, Volulyte, Fresenius Kabi) based on the stroke volume and flow time parameters.
Intervention code [1] 285075 0
Treatment: Other
Comparator / control treatment
The control group will have a "restrictive" fluid regimen as follows:
Maintenance 6mls/kg/hr Hartmann's solution with boluses to replace blood loss. Boluses can be crystalloid or colloid or blood.
Control group
Active

Outcomes
Primary outcome [1] 287458 0
Complication rate: number of complications during hospital stay.
We will use a standardised classfication and severity grading scale, based on the work of Dindo and Clavien.
This has a 17 point classification of complications (eg. Venous thromboembolism, sepsis, AMI). The severity grading scale is a 7 point scale (from I - deviation from normal postoperative course without the need for intervention to V-death).

Summary
Brief summary
During surgery on the bowel it is routine to replace blood and fluid loss with intravenous fluids. However, it is still unclear what the optimal amount and method is to replace this loss. This study compares giving a smaller amount of fluid, called fluid restriction, to giving fluid guided by a cardiac output monitor, called targetted fluid administration. We will assess the impact these two methods have on patient's recovery and also the effect on observed clinical signs such as cardiac output at the end of the operation.
