Use of the oesophageal Doppler for IOFM has been shown to improve patient outcome, in both randomised trials [1-15] and clinical audits [16-20], across a number of different surgical specialties, by reducing the incidence of postoperative complications and length of hospital stay. Although the majority of outcome evidence is from the intraoperative setting, outcome studies have also been published following the use of Doppler-guided fluid management postoperatively, and in intensive care [21-23].
The UK’s National Institute for Health and Care Excellence (NICE) produced guidance on the CardioQ-ODM, recommending its use for IOFM in patients undergoing “major or high-risk surgery or other surgical patients in whom a clinician would consider using invasive cardiovascular monitoring.”
A recent meta-analysis confirms that only the oesophageal Doppler technology is able to bring these benefits (see the table above).
