The ASRA COAGS app has been updated with a universal code base and a fresh new look. This subscription-based app is $6.99/annually or free with ASRA Pain Medicine membership. The app transforms the American Society of Regional Anesthesia and Pain Medicine anticoagulation guidelines for Regional Anesthesia and Interventional Pain Procedures into a quick and easy reference for your practice. It provides rapid access to drug-specific summary information. This version combines the most current recommendations from two separate publications: 1. The 2025 guidelines “Regional anesthesia in the patient receiving antithrombotic or thrombolytic therapy: American Society of Regional Anesthesia and Pain Medicine Evidence- Based Guidelines (Fifth Edition)” published in Regional Anesthesia & Pain Medicine. 2.
