Oesophageal Doppler Monitoring (ODM) has gained support from a number of clinical and regulatory bodies, both within the UK and Internationally, due to the robust evidence available, demonstrating reduced post-operative complications and hospital length of stay;
Meta-analysis of IOFM Outcome Benefit
This meta-analysis has been prepared rigorously and objectively by Deltex Medical’s lead scientist. It is designed to be a valuable resource to everyone interested in the evidence for Intraoperative Fluid Management (IOFM) and may be downloaded and used without any need for permission.

This meta-analysis of published outcome evidence of IOFM using a Stroke Volume Optimisation (‘SVO’) strategy confirms that ODM is the only technology that can reduce both the incidence of complications and the length of hospital stay during surgery.
Studies of ODM-guided SVO for IOFM demonstrate a reduction in the incidence of postoperative complications, whereas studies using an arterial pressure based device (PPWA) to guide SVO for IOFM did not:
ODM-guided IOFM demonstrated a 1.1-day reduction in length of hospital stay, an outcome not obtained with PPWA technologies.
Deltex Medical plans to update the meta-analysis as it becomes aware of further studies newly published in peer reviewed journals to create a ‘living’ up to date meta-analysis.

A number of Randomised Controlled Trials (RCTs) have been conducted using the ODM to guide fluid management during surgery.
Most recently (March, 2018) British Journal of Anaesthesia published the biggest ever positive study into the use of Deltex’s ODM to guide fluid/drug therapy during anaesthesia. Importantly the paper focuses on major surgery undertaken on patients considered to be at low-moderate haemodynamic risk. It can be found here.
The 420 patient, multicentre, randomised, controlled, researcher-blinded study is titled: Effect of goal-directed haemodynamic therapy on postoperative complications in low–moderate risk surgical patients: a multicentre randomised controlled trial (FEDORA trial), J.M. Calvo-Vecino, J. Ripollés-Melchor, M.G. Mythen, R. Casans-Francés, A. Balik, J.P. Artacho, E. Martínez-Hurtado, A. Serrano Romero, C. Fernández Pérez , S. Asuero de Lis
The discussion points out that “A haemodynamic optimization algorithm for management of low-moderate risk patients having major abdominal surgery significantly reduced postoperative complications in the 180 days after surgery. There was a decrease in AKI, acute respiratory distress syndrome, acute pulmonary oedema, pneumonia, and superficial or deep surgical site infection. LOS was shortened…”
See below for a summary of additional RCTs, or the Bibliography for a list of references.
St Thomas’ RCT, July 2016
- Length of Stay significantly shorter in ODM patients (6 vs. 8 days; p=0.01).
- Compared to ODM, LiDCOrapid has poor sensitivity and wide limits of agreement
- Significantly more LiDCOrapid patients treated with vasopressors (56% vs. 33%, p=0.01).
- ODM patients mobilised one day before LiDCOrapid ones (p=0.038).
- ODM and LiDCOrapid are not interchangeable.
Results from a 127 patients, single-centre, patient-blinded, randomised controlled trial for elective colorectal surgery within an enhanced recovery programme, were presented on 6th July 2016 at ACPGBI. Patients received simultaneous monitoring using oesphageal Doppler (ODM) and LiDCOrapid when undergoing both open and laparoscopic surgery. Following randomisation, anaesthetists used one monitor to guide fluid management whilst blinded to the other monitor.
The sensitivity of the LiDCOrapid device was 62%. The limits of agreement between the two monitors were -50% to 54% for percentage change in Stroke Volume (SV). There was no change in observed equivalence between the technologies when readings during vasopressor use or pneumoperitoneum were excluded.
The significant reduction in length of stay in ODM patients is consistent with the results of a meta-analysis of IOFM outcome benefit. Link
The authors concluded:
“Marked disagreement was observed in GDFT guided by LiDCOrapid versus ODM in colorectal ERP patients. Length of stay may be prolonged in the LiDCOrapid group”.
Spanish RCT, May 2016
- 72% reduction in total number of complications from 198 to 56 (p<0.01)
- 45% reduction in number of patients suffering one or more complications, meaning Doppler use saved 28 additional patients from suffering any complication (15% v 28%: p<0.01)
- 2 day reduction in median length of stay (p<0.01)
Results from a 450 patient Spanish Government funded multi-centre RCT were presented at Euroanaesthesia 2016. Patients undergoing major gastrointestinal, urological, gynaecological and orthopaedic surgery were managed using oesophageal Doppler to maintain an optimal Stroke Volume (SV), Mean Arterial Pressure (MAP) >70mmHg and Cardiac Index (CI) ≥2.5l/min/m2, when compared to conventional care.
This is the largest ever intra-operative fluid management RCT and the 12th RCT to show substantial improvements in patient outcomes from use of the 10% Stroke Volume Optimization algorithm guided by oesophageal Doppler.
ODM has since been recommended as the preferred monitor for use within the Spanish National Enhanced Recovery guidelines.
The authors concluded:
Fluid management using ODM guided SV, CI and MAP as “the key parameters, leads to a decrease in postoperative complications in patients undergoing major surgery”.
Oesophageal Doppler Monitoring has gained support from a number of clinical and regulatory bodies, both within the UK and internationally. Robust evidence demonstrates reduced post-operative complications and hospital length of stay.
March 2011 saw the publication of the NICE Medical Technology Guidance for CardioQ-ODM Oesophageal Doppler Monitor (MTG3). The recommendation is specifically for the use of the CardioQ-ODM Oesophageal Doppler Monitor to guide fluid optimisation during surgery in over 800,000 procedures in England annually. The CardioQ-ODM is the only technology with sufficient evidence-base to support such extensive recommendation and guidance. Read More
The British Consensus Guidelines on Intravenous Therapy for Adult Surgery (GIFTASUP) were released in 2008, for dissemination to members of participating professional bodies. GIFTASUP states that a response in SV should be assessed using flow-based technology, intraoperative treatment can reduce complication rates and length of hospital stay and that postoperative monitoring should be carried out in non-elective abdominal and orthopaedic surgery.

The NHS Technology Adoption Centre (NTAC) conducted an audit in over 1300 patients, undergoing a range of surgical procedures in three NHS hospitals. Following the comprehensive evidence from the RCTs, NTAC wanted to determine whether clinicians could be trained to use ODM in ‘real world’ hospital settings and gain the same benefits observed in the tightly controlled clinical studies.

The Société Francais d’Anesthésie et de Réanimation (SFAR) have recently released a set of guidelines entitled ‘Stratégie du remplissage vasculaire périopératoire’ (Guidelines for perioperative haemodynamic optimisation), which are SFAR Board approved. The objective is to ‘highlight perioperative vascular filling practices (VF) as a benefit for patients, for use in daily practice’. The first three recommendations relate directly to ODM and Fluid Management and received the highest possible rating of GRADE1+. Read More
ODM guided fluid management is one of six High Impact Innovations listed in the UK NHS 2011 Innovation Health & Wealth report. Based on comprehensive evidence, the document is subtitled Accelerating Adoption and Diffusion in the NHS.
It “sets out an integrated set of measures that together will support the adoption and diffusion of innovation across the NHS.”
It also “sets a delivery agenda that will significantly ramp up the pace and scale of change and innovation.”
In labelling Deltex’s ODM as a High Impact Innovation, the report talks of its comprehensive evidence base and the NICE forecast that ODM guided fluid management has the potential to benefit 800,000 surgical patients by reducing postoperative complications and consequent length of hospital stay.
