Study information
Scientific title
The effect of pneumatic compression stockings on haemodynamic parameters in haemodialysis patients: a randomised crossover trial
Acronym
Study hypothesis
Primary hypothesis:
To determine the effect of pneumatic compression devices (PCDs), compared to standard of care, on central blood volume in both intradialytic hypotension (IDH) prone and non-IDH prone haemodialysis patients.
Secondary hypothesis:
To determine the effect of PCDs on the haemodynamic response during haemodialysis in both IDH-prone and non-IDH prone patients.
Ethics approval
The University of Calgary Office of Medical Bioethics approved on 2nd October 2008 (ref: ED-21937)

Condition
End-stage kidney disease on haemodialysis
Intervention
For sequence 1, the patient will undergo three HD sessions with PCDs, followed by three HD sessions without PCDs. For sequence 2, the patient will undergo three HD sessions without PCDs, followed by three sessions with PCDs. PCDs will be applied firmly around the calves prior to the initiation of HD with compressions intermittently applied at 40 mmHg throughout HD sessions. Frequencies of the compressions will be three cycles of compressions and decompressions per minute. Each cycle of compression and decompression will last approximately ten seconds. Lower extremities of all patients will be kept horizontal during the dialysis run.
The total duration of treatment is three consecutive HD sessions at 4 hours each; the follow up period is the same.

Primary outcome measure
The change in central blood volume with and without PCDs in both IDH-prone patients and non-IDH prone patients. Central blood volume will be determined using ultrasound dilution technique as per standard procedures. Determined within the first 30 minutes of HD and again within the last 15 minutes of the HD session; this is done for each of the study HD sessions (three with treatment, three with control).
Secondary outcome measures
Determined within the first 30 minutes of HD and again at the last 15 minutes of HD for each of the study sessions:
1. Cardiac output
2. Mean arterial pressure
3. Bioimpedance derived extracellular fluid (ECF) and intracellular fluid (ICF) values
