The first step for a good control of blood pressure in renal patients is adjusting his/her dry weight. Actually, dry weight is assessed based on clinical examination and blood pressure.
The electrical bioimpedance is a simple and portable device. The investigators design a randomized clinical trial for evaluating two ways of getting the best dry weight for hemodialysis patients.
A basal 24h ABPM will be taken before the randomization. Then, 2 weeks later the dry weight be revised, the investigators will get a second 24h ABPM.
End-stage renal disease (ESRD) is a common clinical condition over the world. In this population, the prevalence of systemic hypertension is high and its adequate control can determinate the outcome.
The first step for a good control of blood pressure is giving a dry weight for the patient. We can understand dry weight or target weight as that one which the patient feels comfortable and there aren't clinical signals of volemic overload as edema, dyspnea, orthopnea, jugular turgency, hepatomegalia. Classically, the dry weight is assessed based on clinical examination, blood pressure and experience of hemodialysis staff.
The electrical bioimpedance is a very simple method that possibilities access the corporal compartments, including the body water, using a small and not expensive portable device.
Trying to study new forms for getting the ideal dry weight, we design a randomized clinical trial for evaluating two ways of getting a dry weight for hemodialysis patients.
One group will be dry weight fixed by bioimpedance data and in another group the dry weight will by a clinical protocol.
We will take a 24h ABPM basal from all patients before the randomization. Then, 2 weeks later the dry weight be revised, a second ABPM will be taken. The results will be compared.

Numerous studies have shown a stronger relationship between ambulatory blood pressure (ABP), particularly night ABP, and cardiovascular events/mortality than for office blood pressure (OBP). A previou...

Phenomenon where increased BLOOD PRESSURE readings taken in non-clinical settings (e.g., HOME BLOOD PRESSURE MONITORING) do not replicate in clinical settings.
Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.
PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.
