Evaluating fluid responsiveness after heart surgery
Evaluation of Fluid Responsiveness With Recruitment Maneuver After Sternotomy in Coronary Artery Bypass Surgery
This study is testing if a specific breathing technique can help doctors understand how much fluid heart surgery patients need after their operation.

What this trial studies
This study aims to assess fluid responsiveness in patients undergoing elective coronary artery bypass surgery by measuring hemodynamic parameters before and after a lung recruitment maneuver. Researchers will monitor stroke volume index, cardiac index, and mean arterial pressure while patients are positioned appropriately. Following a lung opening maneuver, they will evaluate changes in these parameters to determine the effectiveness of the maneuver in predicting fluid needs. The study focuses on patients ventilated with a specific lung volume to enhance the reliability of dynamic indices.
Who should consider this trial
Good fit: Ideal candidates are ASA2-3 patients aged 18-80 scheduled for elective coronary bypass surgery.
Not a fit: Patients with severe comorbidities, such as significant heart or lung disease, or those outside the age range may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve fluid management in coronary artery bypass surgery patients, potentially leading to better surgical outcomes.
How similar studies have performed: While similar approaches have been explored, this specific evaluation of fluid responsiveness using a lung recruitment maneuver in this patient population is relatively novel.
