Benefits & Evidence

There is a large amount of evidence in support of individually guided intraoperative fluid management. 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 EDM-guided SV optimization compared with routine fluid administration. Intraoperative optimization of SV using EDM consistently results in reductions in both postoperative complications and length of hospital stay in a range of surgical patients, in both RCTs and ‘real world’ settings. Patients who receive intraoperative fluid management guided by EDM 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 EDM is not limited to surgery. EDM has also demonstrated favourable outcomes when used to guide fluid management in both postoperatively, and in Critical Care.

Evidence Table

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

The table clearly summarises the evidence base to support the use of EDM for Fluid Management Evidence Table.
