Brief Summary

The present study aims at assessing the ability of a new pulse contour device for diagnosing a \>15% stroke volume (SV) increase during patient hemodynamic optimization by fluid challenge in high risk abdominal surgery.

Conditions

Surgery; Cardiac Output, Low

Keywords

High risk abdominal surgery; hemodynamic optimization; stroke volume; pulse contour

Outcome Measures

Primary Outcomes (1)

• Ability of pulse contour for diagnosing a >15% increase in stroke volume

  Ability of pulse contour for diagnosing a \>15% increase in stroke volume

  15 minutes

Secondary Outcomes (2)

• Comparison with the ability of other techniques

  15 minutes

Study Arms (1)

Hemodynamic optimization

Patients scheduled for intermediate and high-risk abdominal surgery were eligible to participate

Diagnostic Test: >15% SV increase during fluid challenge

Interventions

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

Patients scheduled for intermediate and high-risk abdominal surgery were eligible to participate

You may qualify if:

• Adult patient ASA status 1-3 who were orally informed and did refuse to participate.
• Patient in whom general anesthesia with tracheal intubation were planned.
• Patient in whom an arterial catheter and a monitoring of cardiac output by esophageal Doppler were indicated for hemodynamic optimization
• Patient with cardiac sinusal mode

You may not qualify if:

• Patient \< 18-year-old
• Cardiac arrythmia
• Patient with anomaly in oro-pharyngo-esophageal tractus
• Patients with hemostasis anomaly (PT \< 30%, platelets \< 50 000 elements/mm3)
• Patient in whom the cardiac output monitoring or measurement was not possible by Esophageal Doppler or echography
• Patients in whom cardiac arrythmia occurred during the procedure of hemodynamic optimization.
