Do changes in relative blood volume monitoring correlate to hemodialysis-associated hypotension?
INTRODUCTION Intradialytic hypotension remains the most common complication for outpatient hemodialysis, and relative blood volume monitoring was designed to reduce hypotension. Reports of the usefulness of this technology, however, have been variable. METHODS We audited the usefulness of relative blood volume monitoring recorded throughout the mid-week dialysis in 72 stable adult outpatients...
متن کاملRelative blood volume changes underestimate total blood volume changes during hemodialysis.
BACKGROUND Measurements of relative blood volume changes (DeltaRBV) during hemodialysis (HD) are based on hemoconcentration and assume uniform mixing of erythrocytes and plasma throughout the circulation. However, whole-body hematocrit (Ht) is lower than systemic Ht. During HD, a change in the ratio between whole-body to systemic Ht (F cell ratio) is likely to occur as a result of a net shift o...
متن کاملHemodialysis Volume-Associated Ambulatory Blood Pressure Patterns in Hemodialysis Patients
Although volume excess causes hypertension, whether it also affects circadian patterns of arterial pressures among hemodialysis patients remains unknown. To test the notion of whether volume overload is associated with a unique blood pressure (BP) “signature,” a posthoc analysis was performed among 145 patients participating in the Dry-Weight Reduction in Hypertensive Hemodialysis Patients rand...
متن کاملEffects of relative blood volume-controlled hemodialysis on blood pressure and volume status in hypertensive patients.
In hypertensive hemodialysis (HD) patients, dry weight reduction to normalize blood pressure (BP) often results in increased frequency of HD hypotension. Because HD with blood volume tracking (BVT) has been shown to improve intra-HD hemodynamic stability, we performed a prospective, randomized study to test whether BVT is more effective than standard hemodialysis (SHD) in the management of hype...
متن کاملOptimized Blood Volume Monitoring during Hemodialysis Procedure based on Ultrasonic Speed Measurement
Fast reduction of blood water volume due to ultra-filtration via hemodialysis machine and critical threshold of blood water volume can result in clinical complications such as hypotension. When blood water volume reduces during hemodialysis process, the concentration of blood forming elements will increase. One of the methods for the monitoring of the concentration changes is ultrasonic speed m...
