Ambulatory Blood Pressure Monitoring duringRegular Dialyzation Treatment

Overview

Ambulatory monitoring of the blood pressure (AMBP) makes it possible to diagnose in hypertensivepatients the so-called dipper phenomenon, i.e. a drop of the BP during the night provided thatthe patient is asleep. The absence of this phenomenon implies as a rule serious damage of thecardiovascular apparatus, brain or kidneys. By means of an apparatus ABP monitoring type 90207of Space Labs. Inc. a group of 16 patients in regular dialysis treatment (RDT) was examined andthe blood pressures were evaluated before and after dialysis. Patients with the dipper profilereacted more adequately during dialysis i.e. by a drop of the blood pressure due to the loss ofexcessive fluid which they retained during the interdialysis period, as compared with the groupwith a non-dipper profile which may be exposed to a greater risk of cardiovascular complications.The authors conclude that detection of the absence of the non-dipper phenomenon can reveal riskpatients. AMBP can explain so-called paradoxical hypertension at the end of haemodialysis despitemajor removal of fluids by ultrafiltration, and that moxonidine participates in a significantway in the elimination of the non-dipper phenomenon.
