Overview
Brief Summary
Monitoring could secure management for patient but stay invasive. The purpose of this study was to compare,after cardiac surgery, the cardiac output measurement between transpulmonary thermodilution(reference method) and digital photoplethysmography (non invasive) for absolute value and dynamics changes before and after fluid expansion for patients with indication of fluid challenge.
Detailed Description
* The time frame of the study period was included between the arrival at the ICU after cardiac surgery and before spontaneous breathing on mechanical ventilation * Time-to-event outcome measures was period of time between the arrival at the ICU after cardiac surgery and before spontaneous breathing on mechanical ventilation. The event (hypotension) was defined as systolic arterial pressure under 90mmHg,less than 40mmHg, mean arterial pressure under 70mmHg, tachycardia upper 100 beats/min, presence of skin mottling, low cardiac output or previous blood loss.

Outcomes
Primary Outcomes
Correlation, percentage error, bias, precision and limits of agreement for change in cardiac output measured by digital photoplethysmography compared with transpulmonary thermodilution during fluid expansion
Time Frame: During admission in ICU after cardiac surgery and before spontaneous breathing-measurements will be complete within 60 minutes of starting fluid expansion
Analysis of correlation, percentage error, bias, precision and limits of agreement for change in cardiac output measured by digital photoplethysmography compared with transpulmonary thermodilution during fluid expansion
Secondary Outcomes
- Bias and limits of agreement for change in arterial pressure measured by digital photoplethysmography compared with intra radial artery catheter during volume expansion(During admission in ICU after cardiac surgery and before spontaneous breathing-measurements will be complete within 60 minutes of starting fluid expansion)
- Predictive value of fluid responsiveness by the variation of pulse pressure variation measuring by radial artery catheter and digital photoplethysmography(During admission in ICU after cardiac surgery and before spontaneous breathing-measurements will be complete within 60 minutes of starting fluid expansion)
- Predictive value of fluid responsiveness by three different localisation of plethysmographic variability index sensor: forehead, digital and ear position(During admission in ICU after cardiac surgery and before spontaneous breathing-measurements will be complete within 60 minutes of starting fluid expansion)
