Pick the block and the drug: get the bleeding-risk tier and the stop / restart timing.
Draft — not yet clinically verified. Stop/restart times: Association of Anaesthetists 2013 (Table 1),
derived for neuraxial blocks, normal renal function unless stated. Block risk tiers: RA-UK RAPAC
(consultation draft), Table 2. The current definitive sources are ASRA (2025) and ESAIC/ESRA (2022). Not a substitute for clinical judgement.
Dabigatran is renally cleared — the stop time lengthens as clearance falls (ml/min).
Timing: Harrop-Griffiths W, et al. Anaesthesia 2013;68:966–972 (Table 1). Block risk tiers:
RA-UK Regional Anaesthesia in Patients on Anti-Coagulants (RAPAC), consultation draft, Table 2.
Sources: AoA 2013 (drug timing, Table 1) · RA-UK RAPAC draft (block risk, Table 2).
Timing = time to peak + 2 × half-life; assumes normal renal function unless stated.
