The CardioQ™ Oesophageal Doppler Monitor
Deltex Medical’s CardioQ™ monitor uses disposable ultra-sound probes inserted into the oesophagus to determine the amount of blood being pumped around the body – ‘circulating blood volume’. Reduced circulating blood volume is known as hypovolaemia and leads to insufficient oxygen being delivered to the organs. This causes medical complications including peripheral and major organ failure which can lead to death. Hypovolaemia, which is akin to severe dehydration, affects virtually every patient having surgery because of the combined effects of pre-operative starvation, the impact of the anaesthetic agents and trauma from the surgery itself. Using fluids and drugs, guided by the CardioQ™, to optimise the amount of circulating blood significantly reduces post-operative complications allowing patients to make a faster, more complete recovery and return home earlier.
Randomised Clinical Trials (RCTs)
The most rigorous way to test of how well a new medical product works is to compare it with the current ‘standard of care’ – the way that patients would be treated normally – in order to see whether the new product is as good or better than the current approach. The randomised clinical trial is generally accepted as the best way of undertaking such a comparison and seeks to provide as clear an answer as possible about whether a new product helps make patients better more quickly or with fewer complications or improves other such ‘endpoints’ compared to the current standard of care. |
