What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a new pulse contour device can accurately detect increases in stroke volume during a fluid challenge in patients undergoing high-risk abdominal surgery. Researchers will compare the device's readings to those from transthoracic echocardiography. The goal is to improve how doctors manage fluids during surgery to keep the heart pumping effectively.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If accurate, this device could help doctors give fluids more precisely during surgery, potentially reducing complications.
What could go wrong
This is a small, early-stage study focused on accuracy, not patient outcomes. The device may not prove reliable enough for routine use.

Inclusion Criteria: * 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 Exclusion Criteria: * 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.
