Evidence & Benefits

There is a large amount of evidence in support of individually guided intraoperative fluid management (IOFM). The Evidence Table summarises details of the randomised controlled trials (RCTs) and audit studies reporting patient outcome following IOFM.

The consistent evidence supporting IOFM comes from studies utilising ODM-guided SV optimisation compared with routine fluid administration. Intraoperative optimisation of SV using ODM consistently results in reductions in both postoperative complications and length of hospital stay in a range of surgical patients, in both RCT and ‘real world’ settings. Patients who receive intraoperative fluid management guided by ODM exhibit on average:

  • 60% fewer postoperative complications
  • 2 day shorter length of ICU stay
  • 2 day shorter length of hospital stay

The evidence in support of ODM is not limited to surgery. ODM has also demonstrated favourable outcomes when used to guide fluid management in both post-operatively, and in Critical Care.

Evidence Table

This table summarises the clinical outcome evidence regarding Intraoperative Fluid Management (IOFM). Included, within the table, are studies where a cardiac output monitoring technology (such as the ODM) has been used to optimise circulating blood volume during surgery.

The table clearly summarises the evidence base to support the use of ODM for IOFM Evidence Table
