Major US teaching hospital uses CardioQ-ODM to improve patient outcomes and reduce lengths of hospital stay

25 October 2011 - Deltex Medical Group plc ("Deltex Medical", "Company" or "Group"), the global leader in oesophageal Doppler monitoring ("ODM"), notes the first publicised results from implementing its CardioQ-ODM system in surgery in the USA within an enhanced recovery programme.

Doctors from Duke University Hospital, North Carolina, presented their findings from implementing enhanced recovery in bowel surgery to doctors attending the American Society of Anesthesiologists annual meeting in Chicago on 14-19 October 2011. The Duke protocols include the use of CardioQ-ODM for fluid management during surgery. Key findings from the first 142 patients included:

·      100% of cases were treated under the enhanced recovery protocols within six months;

·      89% compliance with the part of the protocol requiring fluid management using CardioQ-ODM during surgery;

·      lengths of hospital stay for patients undergoing open surgery were reduced 40% from 11.8 to 7.1 days;

·      lengths of hospital stay for patients undergoing laparoscopic surgery reduced 25% from 6.5 to 4.9 days; and

·      post operative wound infections and urinary tract infections were both almost halved.

The results from Duke were also presented alongside an update on the roll-out of enhanced recovery programmes in the NHS in England at a reception in Chicago hosted by the British Consul General and attended by senior clinicians invited from some of North America's most prestigious hospitals.

Ewan Phillips, Deltex Medical's chief executive, commented:

"The impact of implementing CardioQ-ODM as a key step in Duke's enhanced recovery programme is an important breakthrough for Deltex Medical in the USA. The US healthcare system needs to find ways to deliver better care at lower cost: showing the benefits of implementing CardioQ-ODM in one of America's leading hospitals provides a powerful and current example of how to do this.

"Duke is one of the very first US hospitals to embrace enhanced recovery and is already considering expanding its implementation into other types of surgery as well as continuing to assess the impact in bowel surgery. Over 300 patients have now been through the bowel surgery programme."

Notes for Editors

Deltex Medical manufactures and markets the CardioQ-ODMÔ system. CardioQ-ODM changes the way doctors care for surgical patients allowing them to recover faster and leave hospital sooner and in better health than they otherwise would do. The performance of the system has been validated through independently conducted, randomised controlled clinical trials and is being translated into routine clinical practice in leading hospitals around the world.

CardioQ-ODM comprises a monitor and a single patient disposable probe. The probe is placed into the oesophagus through either the mouth or nose and the tip positioned facing the adjacent descending aorta. A low frequency ultrasound signal, generated by the monitor, is bounced off the blood travelling down the aorta and the Doppler principle is used to determine the velocity of the blood flow, expressed in distance per cardiac cycle - 'Stroke Distance'. The monitor also calculates the amount of time that blood is flowing down the aorta as a proportion of a cardiac cycle - 'Flow Time'.

The monitor uses a validated proprietary nomogram to extrapolate volumetric data (Stroke Volume, Cardiac Output etc) from the directly measured flow velocity. The nomogram utilises the patient's age weight and height, effectively to estimate the size of the aorta in which the velocity of the flow is being measured. Crucially this means that any reported relative change in Stroke Volume is absolutely identical to the relative change in the directly measured flow velocity variable of Stroke Distance. CardioQ-ODM immediately and reliably identifies even very small changes in the blood flow velocity allowing doctors to intevene earlier and on smaller changes than with any other approach.

Intra-operative individualised Doppler guided fluid management entails insertion and focusing of the probe to obtain a baseline reading, giving a small (200 to 250 ml) fluid challenge directly into the vascular system and seeing if Stroke Volume (or Stroke Distance) increases by more than 10%. If the increase is more than 10%, repeat fluid boluses are administered until such time as the increase is less than 10%: after this no further fluid is given unless Stroke Volume falls by more than 10% - the process is designed to achieve and maintain the individual patient's optimal Stroke Volume. CardioQ-ODM is also used during surgery to guide administration of vaso-active agents such as inotropes.

The CardioQ-ODM helps patients by enabling doctors to reduce the complications that arise from a medical condition that is common to almost all patients having surgery and many others in intensive care or arriving in the accident and emergency department. This condition is known as hypovolaemia - a reduction in circulating blood volume - and in surgical patients arises as a direct consequence of the combined effects of pre-operative starvation, the anaesthetic agents and the blood and fluid losses associated with the surgical procedure itself. Hypovolaemia means that the body struggles to get sufficient blood to the tissues and vital organs which are consequently starved of essential oxygen. This can cause medical complications including peripheral and major organ failure, which if not dealt with quickly can lead to severe compromise or even death.

There are already over 2,300 CardioQ-ODMs currently in use in hospitals worldwide and distribution arrangements are in place in over 30 countries. In addition, there are currently more than 250 clinical publications on the use of the CardioQ-ODM which have repeatedly:-

·    Validated the results of CardioQ-ODM against known standards for measuring cardiac output

·    Proved that CardioQ-ODM works in a wide range of surgical procedures

·    Proved that CardioQ-ODM delivers 50% or more reductions in post-operative complications and 25% or more reductions in length of hospital stay: better care at lower cost.

The SupraQÔis an entirely non-invasive device which uses an ultrasound probe held at the base of the patient's neck to track the flow of blood in the aorta; it presents the same data as the CardioQ-ODM in a similar format and is used for taking snapshots or monitoring over short periods.
