MAnnitol for Blood Pressure Stability in HemoDialysis (MAP-HD)
February 13, 2024 updated by: Finnian McCausland, Brigham and Women's Hospital
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.
