Study summary

Kidney failure can result from a variety of conditions and can be temporary or permanent. Hemodialysis is available as a replacement treatment to perform the work that the kidneys normally do. However, the dialysis procedure can be associated with rapid changes in the composition of the blood - this may lead to changes in blood pressure and in turn reduced blood supply to important parts of the body. We aim to investigate if giving a medicine (called mannitol) during dialysis may be able to reduce the frequency of these low blood pressure events.

Study arms

  • Placebo comparator
    Placebo group: (0.9% normal saline)

    0.9% saline will be administered (IV) during the hemodialysis session at 1.25mL/kg/hour (max 375mLs per session). Administration will be discontinued 30 minutes before the end of the hemodialysis session.

    Drug: 0.9% saline

  • Active comparator
    Intervention: intravenous mannitol (20%)

    Mannitol will be administered (IV) during the hemodialysis session at a maximum rate of 0.25g/kg/hour (maximum rate 25g/hour; maximum 75g per session; maximum volume 375mLs per session). Administration will be discontinued 30 minutes before the end of the hemodialysis session.
