Perioperative Anticoagulant Use for Surgery Evaluation -2 (PAUSE-2) Study Patients Receiving a Direct Oral Anticoagulant (DOACs-Dabigatran, Rivaroxaban, Apixaban or Edoxaban) and Needing Elective High-Bleed-Risk Surgery or an Invasive Procedure: A Randomized Control Trial
McMaster University
Summary
PAUSE 2 study is a prospective, open-label, blinded-endpoint non-inferiority RCT of PAUSE vs. ASRA management in DOAC treated high risk patients with AF/VTE who need elective high bleed risk surgery/procedure and/or any procedure involving neuraxial anesthesia. The purpose of the PAUSE 2 study is to show that PAUSE management will be as safe (i.e., non-inferior) as ASRA management, with 95% of patients having low/undetectable pre-operative DOAC levels \<30 ng/mL in each group., at the time of surgery/neuraxial.
Description
As use of direct oral anticoagulants (DOACs) continues to increase so too will the need to manage such patients who require a surgery/procedure. Perioperative DOAC management is established and guideline supported in patients who need a low/moderate-bleed-risk surgery/procedure (e.g., hernia repair, colonoscopy), but there is uncertainty about managing high-risk patients who need a high-bleed-risk surgery (e.g., orthopedic, cardiac) or any neuraxial (i.e., spinal, epidural) anesthesia/procedure. The management of patients who are taking a DOAC (apixaban, dabigatran, edoxaban, rivaroxaban) and…
