Cardiopulmonary Bypass Emergencies and Intraoperative Issues

Area of Science:

• Cardiovascular Surgery
• Biomedical Engineering
• Anesthesiology

Background:

• Cardiopulmonary bypass (CPB) is critical for cardiac surgery but presents significant safety and biomechanical challenges.
• Intraoperative emergencies during CPB can compromise patient safety and surgical success.
• Effective management strategies are essential for mitigating risks associated with CPB.

Purpose of the Study:

• To review preventative and intraoperative management strategies for common CPB emergencies.
• To consolidate knowledge on addressing complications related to CPB.
• To enhance the safety and efficacy of CPB in cardiac surgery.

Main Methods:

• Narrative review of intraoperative cardiopulmonary bypass emergencies.
• Discussion of preventative measures and management protocols.
• Identification of key complications and their solutions.

Main Results:

• Cannulation complications include dissection, malposition, and gas embolism.
• CPB equipment failures involve heater-cooler, oxygenator, electrical systems, and tubing.
• Other critical issues include circuit thrombosis, medication errors, awareness, and TAVR-specific CPB challenges.

Conclusions:

• Proactive identification and management of CPB emergencies are crucial.
• Addressing cannulation, equipment, and circuit-related issues improves CPB safety.
• Comprehensive strategies are needed for managing diverse CPB complications, including during transcatheter aortic valve replacement.
