Sir,
We are concerned that risks of using concentrated sodium citrate for a catheter lock solution (CIT) are not well understood. Routine haemodialysis is safe, partly as a result of European Standards requiring medical devices to be safe even under fault conditions [1]. Risk analysis taking foreseeable user errors (FUE) into account is part of the process of obtaining approval to market a new medical product. Medical practitioners are not bound to this process and may neglect the effects of user errors.
During development of a low concentration citrate-containing lock solution we carried out
