The Role of Dynamic Arterial Elastance in Predicting Vasopressor Requirement After Anesthesia Induction in Patients Undergoing Elective On-Pump Coronary Artery Bypass Graft Surgery
Status: Recruiting
Location: See location...
Intervention Type: Other
Study Type: Observational
SUMMARY
This study aims to determine whether dynamic arterial elastance (EaDyn), measured after anesthesia induction, can predict the need for vasopressor treatment in patients undergoing elective on-pump coronary artery bypass graft surgery. EaDyn will be calculated from pulse pressure variation and stroke volume variation. Hemodynamic measurements will be recorded before anesthesia induction and at 1, 3, and 5 minutes after induction. The study is prospective and observational, and no additional intervention will be performed as part of the study.
