Implementation of CardioQ-ODM in Canadian hospital system

18 July 2011 - Deltex Medical Group plc ("Deltex Medical" or the "Company"), the global leader in oesophageal Doppler monitoring ("ODM"), today announces the start of a programme by a hospital system in Canada to implement its CardioQ-ODM products as a standard of care.

Doctors in the Interior Health system in British Colombia in Canada are implementing CardioQ-ODM in all bowel surgery in each of the hospitals with colorectal specialties. The impact of the adoption of CardioQ-ODM will be audited both within the context of introducing an enhanced recovery surgical programme and also with a view to expansion into other types of surgery.

Dr Ron Collins, Chair of Interior Health Authority's Anesthesia Working Group commented:

"In an effort to improve safety for patients having colorectal surgery, Interior Health will be trialling a new technology that has been demonstrated to reduce complications and speed recovery after major surgery. This technology is non-invasive and inexpensive; it guides fluid administration in the operating room to improve oxygen delivery during surgery. The trial will include all the surgery sites within Interior Health that perform these operations.  Interior Health is the first Health Authority in Canada to widely embrace this proven technology for the benefit of colorectal surgical patients. This is one of several important surgical patient safety initiatives supported by Interior Health."

Ewan Phillips, Deltex Medical's Chief Executive, commented:

"A key part of our export strategy is to tailor the implementation models we have developed in the UK to other developed health systems and this project in Canada is one of the first examples. We expect that successful implementation of CardioQ-ODM in colorectal surgery in the Interior Health system will both accelerate its adoption in colorectal surgery in other hospital systems and facilitate expansion of its use within Interior Health into other surgical areas."

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-ODMscurrently 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-ODMagainst known standards for measuring cardiac output

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

·    Proved that CardioQ-ODMdelivers 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-ODMin a similar format and is used for taking snapshots or monitoring over short periods.
