Bivalirudin dosing during prolonged intermittent renal replacement therapy: a case report.

As patients transition between dialysis modalities, and from the intra- to the inter-dialytic period, medications with a narrow therapeutic index that are cleared in dialysis may require dose adjustments and close monitoring. Three cases of patients receiving bivalirudin while converting from continuous to prolonged intermittent renal replacement therapy are reported. Details provided include flow rates and ultrafiltrate volume. In these cases, it appears pre-emptive dose adjustments may be unwarranted, and clinicians should be aware of potential rebound after cessation of dialysis.
