FloTrac-Guided Hemodynamic Monitoring Optimizes ERAS Implementation in Coronary Artery Bypass Surgery: A...

Area of Science:

• Cardiac Surgery
• Anesthesiology
• Critical Care Medicine

Background:

• Enhanced Recovery After Surgery (ERAS) protocols aim to reduce complications and length of stay in cardiac surgery.
• The impact of ERAS implementation and hemodynamic monitoring on outcomes in isolated coronary artery bypass grafting (ISO-CABG) remains understudied.

Purpose of the Study:

• To evaluate the effect of ERAS implementation on cardiovascular patients undergoing elective ISO-CABG.
• To assess the role of continuous hemodynamic monitoring within an ERAS protocol.

Main Methods:

• Retrospective analysis of 380 patients undergoing elective ISO-CABG.
• Patients were stratified into three groups: pre-ERAS, ERAS without hemodynamic monitoring, and ERAS with FloTrac-guided monitoring.
• Primary outcomes included extubation time and ICU length of stay; secondary outcomes assessed hemodynamic stability.

Main Results:

• Mean extubation time significantly decreased with ERAS implementation, with the greatest reduction observed in the ERAS with hemodynamic monitoring group (5 hours 54 minutes).
• Hypotension duration and area under the threshold for mean arterial pressure <65 mmHg were significantly reduced in the hemodynamic monitoring group.
• ICU length of stay showed a non-linear pattern, with the hemodynamic monitoring group having a shorter stay compared to ERAS without monitoring.

Conclusions:

• ERAS implementation shows modest improvements in extubation time for ISO-CABG patients.
• Full ERAS protocol integration with hemodynamic monitoring yields the most favorable outcomes regarding extubation time and hemodynamic stability.
• Optimizing perioperative outcomes requires active clinician engagement with real-time physiologic data within the ERAS framework.
