NCT03474224

Brief Summary

In this prospective observational study investigators aim to seek for any possible correlation between the venous to arterial carbon dioxide difference (pCO2 gap) at the end of surgery and the percentage of time spent above a predefined threshold of stroke volume (SV) andn mean arterial pressure (MAP).

Outcome Measures

Primary Outcomes (2)

  • Correlation between the time-in target of MAP and the pCO2 gap at the end of surgery

    The primary outcome will explore the hypothesis that patient with higher adherence of MAP levels above 65 mmHg will have a lower pCO2 gap at the end of surgery

    an average of 8 hours

  • Correlation between the time-in target of SV and the pCO2 gap at the end of surgery

    The co-primary outcome will explore the hypothesis that patient with higher adherence of SV within the maximum value with a 10% tolerance, will have a lower pCO2 gap at the end of surgery

    an average of 8 hours

Secondary Outcomes (2)

  • incidence of postoperative overall complications

    up to 30 days

  • duration of hospitalization

    an average of 2 weeks

Study Arms (1)

FloTrac patients

patients belong to this group will be managed with a stroke volume target hemodynamic protocol

Device: Ev1000 Clinical Platform from Edwards Lifesciences

Interventions

The EV1000 Hemodynamic monitoring platform will be used to guide fluid administration following a volume-based parameter such the stroke volume.

FloTrac patients
