- pp: 4-6h after sVD
- pp: 6-12h after CS
Only different with epidural sp del
- Unfractionated:
- —-ppx: restart 1h after placement or removal of catheter
- —-thera: 1h after placement or removal of catheter
- LMWH:
- —ppx 12 after placement or 4 hours after removal
- —thera: 24h after placement or 4 hours after removal
