[Coagulation disorders in the context of cardiac surgery - Clinical basics and mechanism based therapy]

Area of Science:

• Cardiology
• Hematology
• Anesthesiology

Background:

• Intra- and postoperative bleeding disorders are frequent complications in cardiac surgery.
• Perioperative coagulopathy typically arises from a complex interplay of acquired and inherited conditions.
• Effective management is crucial for minimizing complications and improving patient prognosis.

Purpose of the Study:

• To outline the differential diagnosis of microvascular bleeding in cardiac surgery.
• To emphasize the importance of timely detection and rigorous treatment of coagulopathies.
• To highlight the role of point-of-care systems and institutional algorithms in managing these disorders.

Main Methods:

• Review of common causes of perioperative coagulopathy.
• Discussion of diagnostic approaches including altered homeostasis and coagulation factor deficiencies.
• Emphasis on utilizing point-of-care testing and evidence-based algorithms.

Main Results:

• Differential diagnosis includes altered homeostasis, impaired primary hemostasis, antithrombotic use, dilutional/consumptive coagulopathy, fibrinolysis, and factor deficiencies.
• Point-of-care systems enable rapid bedside analysis for prompt diagnosis and intervention.
• Individualized, regularly revised algorithms can optimize resource utilization.

Conclusions:

• Timely diagnosis and treatment of perioperative coagulopathy are essential for reducing transfusion needs and preventing reoperations.
• Point-of-care systems facilitate early detection and intervention.
• Structured, adaptable algorithms can lead to more efficient and effective patient management in cardiac surgery.
