“Regional Anaesthesia and Antithrombotic Therapy — Updated ESAIC/ESRA Guidance

Managing regional anaesthesia in patients taking antiplatelet or anticoagulant medications remains one of the most delicate balance points in modern anesthesia. The updated ESAIC/ESRA guidelines (“Regional anaesthesia in patients on antithrombotic drugs: Joint ESAIC/ESRA Guidelines”) provide a comprehensive, evidence-based framework to reduce the risk of bleeding complications—especially neuraxial and deep peripheral block–related hematomas.
Key Takeaways from the 2022 ESAIC/ESRA Joint Guidelines:
1. Timing Is Critical
Strict time intervals must be respected before and after neuraxial or deep peripheral nerve blocks.
These intervals depend on:
- Drug class (VKA, DOACs, LMWH, UFH, antiplatelets)
- Dose (low vs high)
- Renal function
- Whether puncture was traumatic
- Need for catheter insertion/removal
- Superficial blocks, however, do not require withholding antithrombotic therapy.
2. Deep vs Superficial Blocks
- Deep blocks = follow neuraxial rules due to high bleeding risk.
- Superficial blocks = generally safe without stopping anticoagulants.
3. Lab Testing Helps in High-Risk Cases
Drug-level assays (anti-Xa, thrombin time, DOAC levels, INR) can guide safer timing—especially in renal impairment or when exact timing is uncertain.
4. Reversal Agents Have a Role
In emergencies:
- VKA reversal → PCC + vitamin K
- Dabigatran reversal → Idarucizumab
- Other agents (andexanet alfa, PCC for DOACs) do not change timing recommendations.
5. Ultrasound Guidance Is Strongly Recommended
Ultrasound reduces vascular puncture and increases safety—especially in anticoagulated patients.
6. Post-Block Vigilance Is Essential
All patients undergoing neuraxial/deep blocks while on antithrombotics require:
- Regular neurological checks for ≥24 hours
- Rapid imaging (MRI preferred) if deficits appear
- Urgent decompression within 6 hours if hematoma suspected
Bottom Line
Safe regional anaesthesia in anticoagulated patients demands a nuanced, individualized approach based on drug class, timing, block type, and patient-specific risk factors. These updated ESAIC/ESRA guidelines provide a clear roadmap to enhance safety, prevent catastrophic bleeding complications, and support multidisciplinary decision-making.
