Bovine pericardium has become a trusted biological material in modern surgery — particularly in cardiac, vascular, and soft tissue reconstruction. To maintain its mechanical integrity and biocompatibility, it’s crucial to handle and store this tissue correctly. Below are the best practices for surgeons, surgical nurses, and hospital staff to ensure optimal performance and patient outcomes.

🔍 Understanding the Forms of Bovine Pericardium

Bovine pericardium is available in different preservation formats, each requiring specific handling:

• Chilled: Stored at +2°C to +8°C
• Frozen: Stored at −80°C or in ultra-low freezers
• Lyophilized (if applicable): Shelf-stable, rehydrated before use

Each format has unique preparation protocols and shelf lives. Always refer to the product’s IFU (Instructions for Use).

🧊 1. Storage Conditions

• Chilled products must be stored in a refrigerator at +2°C to +8°C.
  Do not freeze. Use before expiration date (typically 14–30 days from packaging).
• Frozen products should be kept in −80°C freezers or dry ice containers during transport.
  Thawing must be done gradually under sterile conditions.
• Never store bovine pericardium at room temperature unless it is specifically labeled as lyophilized.

🧼 2. Aseptic Handling in the Operating Room

• Open the sterile packaging only when the surgical team is ready to use the graft.
• Use sterile instruments and avoid contact with non-sterile surfaces.
• If the graft is in liquid preservative, rinse thoroughly with sterile saline or balanced salt solution as per manufacturer’s guidelines.
• Avoid excessive stretching or folding of the tissue.

⏱ 3. Timing and Preparation

• Once removed from storage, use the graft within the recommended time window (usually within 30 minutes to 2 hours, depending on format).
• If thawing is required, follow manufacturer-recommended protocols — typically done in sterile saline at room temperature or in a water bath.

⚠️ 4. Common Mistakes to Avoid

• Do not refreeze tissue after thawing.
• Do not cut or modify the graft outside sterile field.
• Do not mix with alcohol, antiseptics, or other substances unless approved.

📝 5. Documentation and Traceability

• Record lot number, expiration date, and handling time in the patient’s surgical record.
• Some surgical centers integrate biologic grafts into digital inventory systems for compliance and quality assurance.

✅ Final Thoughts

Proper handling and storage of bovine pericardium are essential for preserving its strength, elasticity, and compatibility with human tissue. Following best practices ensures surgical success and patient safety — and prolongs the shelf life and effectiveness of this valuable biological material.
