Effect of Intradialytic Change in Plasma Volume on Blood Pressure in Patients Undergoing Maintenance Hemodialysis
BACKGROUND: Hypervolemia is a common complication in patients on hemodialysis (HD). To determine the effect of volume change on blood pressure in HD population, this cohort was conducted. MATERIALS AND METHODS: The study population was composed of 60 non-diabetic patients on maintenance HD, with mea...

Sumario: | BACKGROUND: Hypervolemia is a common complication in patients on hemodialysis (HD). To determine the effect of volume change on blood pressure in HD population, this cohort was conducted. MATERIALS AND METHODS: The study population was composed of 60 non-diabetic patients on maintenance HD, with mean age of 59.95±15.28 years. They were divided into hypertensive group A (n=26) and normotensive group B (n=34). Data were collected by a questionnaire. Pre and post-dialysis blood levels of urea, sodium, total protein, and hemoglobin were measured and intradialytic change of plasma volume were calculated. Data analyses were performed by the SPSS v.16. RESULTS: Out of 60 patients, 58.3% were male and 41.7% female. Post-dialysis systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly lower than pre-dialysis values in both groups (P=0.001, each). No correlation was found between intradialytic change in plasma volume or body weight and alterations of SBP or DBP during HD in the study groups (P>0.05, each). Intradialytic changes of body weight did not correlate to intradialytic changes of plasma volume (P=0.15). CONCLUSION: HD effectively reduces blood pressure and volume expansion, however, intradialytic changes of plasma volume and body weight do not influence on SBP and DBP. |
