Rotational thromboelastometry in prediction of bleeding after cardiac surgery

Area of Science:

• Cardiovascular Surgery
• Anesthesiology
• Hematology

Background:

• Reexploration after cardiac surgery is linked to increased mortality and morbidity.
• Preventing postoperative bleeding is crucial for patient safety and outcomes.
• Identifying patients at risk for bleeding is essential for appropriate management.

Purpose of the Study:

• To evaluate the effectiveness of Rotational Thromboelastometry (ROTEM) in predicting postoperative bleeding.
• To determine if ROTEM can identify patients requiring reexploration after coronary artery bypass graft (CABG) surgery.

Main Methods:

• Prospective enrollment of 400 patients undergoing first-time CABG surgery.
• ROTEM testing performed preoperatively and 30 minutes post-heparin reversal.
• Patients categorized into groups based on postoperative bleeding and need for reexploration.

Main Results:

• 42 out of 400 patients required reexploration, experiencing longer hospital stays and higher mortality.
• Abnormal preoperative ROTEM results were significantly more common in patients needing reexploration (33.3% vs. 2.8%).
• Postoperative ROTEM abnormalities were also significantly higher in the reexploration group (33.3% vs. 1.7%).

Conclusions:

• ROTEM analysis before and after heparin reversal effectively identifies patients at increased risk of postoperative bleeding.
• Early detection of bleeding risk through ROTEM can guide management strategies.
• Utilizing ROTEM testing can potentially reduce reexploration rates and associated complications.
