Perioperative use of prothrombin complex concentrates

Area of Science:

• Hematology
• Pharmacology
• Anesthesiology

Background:

• Prothrombin complex concentrates (PCCs) are plasma-derived products containing vitamin K-dependent clotting factors.
• PCCs are crucial for reversing the anticoagulant effects of vitamin K antagonists (VKAs).
• Current indications include bleeding, overdose, or emergency surgery in patients on VKAs.

Purpose of the Study:

• To review the use of PCCs in the perioperative setting.
• To propose evidence-based algorithms for PCC administration and dosing.
• To guide rapid International Normalized Ratio (INR) normalization for emergency procedures.

Main Methods:

• Review of existing literature on PCCs and VKA reversal.
• Development of two distinct algorithms for PCC use.
• Algorithm 1: Dosing for bleeding patients/pre-urgent surgery based on INR and clinical status.
• Algorithm 2: Reversing oral anticoagulants based on surgical urgency.

Main Results:

• PCCs offer a rapid and complete reversal of VKA effects compared to fresh frozen plasma.
• PCCs are safe and effective when used appropriately for approved indications.
• Algorithms facilitate timely INR normalization, minimizing bleeding risk in perioperative scenarios.

Conclusions:

• PCCs are a vital tool for managing VKA-related bleeding and perioperative hemostasis.
• Proposed algorithms provide a structured approach to PCC dosing and administration.
• Optimized PCC use enhances patient safety during urgent surgical interventions.
