Brief summary

This proposal will measure the effects of mannitol administration versus placebo in hypotensive-prone, adult, maintenance hemodialysis patients with respect to changes in patient symptoms and blood pressure stability.

Detailed description

A randomized crossover trial of hypertonic mannitol vs. placebo in IDH-prone participants will be performed over a 4-week period to determine the effect on: * Patient symptoms * The magnitude of intra-dialytic hypotension The hypothesis to be tested is that the use of hypertonic mannitol will result in fewer adverse symptoms and less decline in intra-dialytic BP, compared with the use of placebo.

Design outcomes

Primary

MeasureTime frameDescription
Patient Symptoms4 weeksComparison of average patient symptom score during mannitol arm using dialysis symptom index compared with the average score during the placebo arm (scale 0-150; higher scores worse)

Secondary

MeasureTime frameDescription
Patient Symptoms4 weeksComparison of average patient symptom score during mannitol arm using modified Edmonton symptom assessment system compared with the average score during the placebo arm (scale 0-100; higher scores worse)
Intra-dialytic hypotension4 weeksComparison of change in average intra-dialytic systolic blood pressure change during mannitol arm, compared with during the placebo arm
