Cerebral Microembolism During Hemodialysis
There is increasing evidence that renal replacement therapy (= continuous veno-venous hemodialysis) generates cerebral microembolism which is detectable on transcranial Doppler ultrasound.
The aim of this study is to monitor patients with transcranial Doppler under two conditions: during hemodialysis and in a hemodialysis-free interval (in each period cerebral embolic load is detected during 30 minutes).
The study hypothesis is that during hemodialysis the cerebral embolic load is significantly higher than in the hemodialysis-free interval.

|Study Design:||Observational Model: Case-Only
Time Perspective: Prospective
|Official Title:||Quantity, Quality and Laterality of Cerebral Microembolism During Veno-Venous Hemodialysis.|
- Quantity of cerebral embolic load [ Time Frame: 30 minutes ]Cerebral embolic load is measured in a 30 minutes-interval during hemodialysis and in a hemodialysis-free interval.
- Quality and laterality of cerebral embolic load [ Time Frame: 30 minutes ]Quality (solid vs. gaseous) and laterality (left vs. right hemispheric dominance) of cerebral embolic load is measured in a 30 minutes-interval during hemodialysis and in a hemodialysis-free interval.

Patient on Hemodialysis
Device: Renal hemodialysis (Fresenius 2008K, Bad Homburg, Germany)
Renal replacement therapy is frequently used in patients with renal failure in order to eliminate substances obligatory excreted by the urine.
