Plain English summary of protocol

Background and study aims
Cardiac output is the volume of blood pumped by the heart per minute. Monitoring the cardiac output to guide fluid administration has been shown to benefit patients undergoing major colorectal surgery, improving their outcomes and reducing the length of hospital stay. The aim of this study is to detect any differences in patient outcome with the use of the LiDCOrapid monitor compared with conventional oesophageal Doppler monitoring.

Who can participate?
Patients undergoing elective colorectal surgery.

What does the study involve?
Both monitors are set up and the participant is randomly allocated to have their fluid administration guided by either LiDCOrapid or oesophageal Doppler. The anaesthetist is not able to see the measurements from the other monitor, but paired measurements are taken throughout. Patient outcomes are collected during their hospital stay and follow-up.

What are the possible benefits and risks of participating?
There is established evidence behind the use of both LiDCO and oesophageal Doppler monitoring and both are already in widespread use. An interim analysis will take place once half of the participants have been recruited to avoid harm if significant differences in outcome are detected.

Where is the study run from?
St Thomas' Hospital (UK)

When is the study starting and how long is it expected to run for?
May 2011 to October 2013

Scientific title	Comparison of goal-directed fluid optimisation guided by LiDCOrapid and conventional oesophageal Doppler effect on intra-operative oxygen delivery index and post-operative outcomes: a randomised control non-inferiority study
Study objectives	Intra-operative goal-directed fluid optimisation guided by LiDCOrapid achieves non-inferior oxygen delivery index optimisation and equivalent patient outcomes compared to oesophageal Doppler monitoring.
Ethics approval(s)	NRES Committee London - Westminster, ref: 11/H0802/9
Health condition(s) or problem(s) studied	Improving perioperative care for elective colorectal surgery
Intervention	Anaesthetist randomised to use either: 1. LiDCOrapid in intervention group OR 2. Conventional oesophageal Doppler cardiac output monitoring in control arm to guide goal-directed fluid therapy Both monitors will be attached intraoperatively to allow paired readings. The anaesthetist will be blinded to the measurements of other monitor not being used.
