Condition
Dialysis-induced myocardial stunning
Intervention
Each patient undergoes one week (three dialysis treatments) of standard haemodialysis, and one week (three dialysis treatments) of standard haemodialysis with supplemental oxygen to breathe; the chronological order of the two weeks is allocated by randomisation. Patients thereby act as their own controls. Monitored visits occur on the third treatment of each week. There is no further follow-up.
Intervention type
Drug
Phase
Not Applicable
Drug names
Dialysate magnesium
Primary outcome measure
Development of regional wall motion abnormalities.
Key observations are taken pre-dialysis (baseline), 15 minutes prior to end of dialysis (peak stress) by cardiac echocardiography (for later offline semi-automated analysis for regional wall motion abnormalities).
Secondary outcome measures
Haemodynamic variables observed pre-dialysis, and throughout dialysis treatment, with continuous non-invasive measurement by finometer, and NICOM (bioreactance).
