Epidural catheter in place, rivaroxaban restarted 14 hours ago. When is it safe to remove?
58-year-old male post-cardiac surgery. Thoracic epidural running. Rivaroxaban restarted 14 hours ago on the cardiac team's instruction. The ward asks: can we remove the catheter now?
Clinical scenario
58-year-old male. Elective CABG completed approximately 36 hours ago. Thoracic epidural catheter in situ for post-operative pain control. Rivaroxaban 20 mg once daily was restarted on the cardiac team's instruction 14 hours ago. The ward nurse contacts you: 'The team wants to remove the epidural catheter this morning.'
The patient is comfortable on the epidural infusion with good analgesia. He is hemodynamically stable. The cardiac team is keen to restart full anticoagulation and mobilize.
Catheter removal carries the same neuraxial risk as insertion
Epidural catheter removal disrupts the epidural venous plexus and carries equivalent spinal hematoma risk to catheter insertion. The ASRA 2022 consensus applies the same strict 72-hour withhold to removal as to insertion — this is why the timing of anticoagulation restart must be coordinated before the first post-operative dose is given, not after.
| Field | Value |
|---|---|
| DOAC | Rivaroxaban |
| Technique | Epidural catheter removal (neuraxial equivalent) |
| Last dose | 14 hours ago |
| Typical requirement | 72 hours from last dose — strict tier (ASRA 2022) |
Restarting DOAC resets the withhold clock
Count 72 hours from the most recent dose — not from surgery, not from when anticoagulation was 'restarted as planned.' A dose given 14 hours ago means the earliest safe removal window opens approximately 58 hours from now. Discuss bridging analgesia with the acute pain team in the interim.
Rivaroxaban was given 14 hours ago. The team wants to remove the catheter now. What do you do?
- 1.
⚠ the window counts from the last rivaroxaban dose (14h ago), not from surgery — 72h not met
- 2.
✓ correct — catheter removal requires the same strict tier as insertion
- 3.
⚠ the withhold window must be completed before removal — holding future doses does not retroactively clear the current one
Teaching points
- Epidural catheter removal carries the same neuraxial hematoma risk as insertion — apply the strict 72h tier for all Xa inhibitors, including for removal.
- Always count the withhold window from the most recent dose. Restarting anticoagulation post-operatively resets the clock — 72h from last dose, regardless of when surgery occurred.
- Coordinate anticoagulation restart timing with all teams before the first post-operative dose is given. Once the dose is administered, the removal window is set.
Use the DOAC tool to verify the withhold window for epidural catheter removal — and to check what the timeline looks like from the last dose.

What about deeper fascial plane blocks like the quadratus lumborum — do they use the 24h standard tier or the strict 72h tier?

Spinal anesthesia tomorrow — but apixaban was taken this morning. Can you proceed?
67-year-old female on apixaban for atrial fibrillation. Last dose 12 hours ago. Surgery scheduled for tomorrow morning. Does the timing work?
QL block with edoxaban — standard tier or strict tier?
Quadratus lumborum block planned for post-operative analgesia. Patient is on edoxaban. Is this a 24-hour or 72-hour withhold?
TAP block with apixaban — why does 24 hours suffice here?
Transversus abdominis plane block planned. Apixaban 5 mg twice daily. Same drug as the spinal case — but why is the window different?
