POS-814 INTRADIALYTIC RELATIVE BLOOD VOLUME MONITORING IN HEART FAILURE PATIENTS: RETROSPECTIVE DATA ANALYSIS

Volume management related complications are common during hemodialysis (HD). There is a narrow window between avoiding and obtaining euvolemic individual, who at their dry weight.Relative Blood (RBV) monitoring via Crit-Line utilizes photo optical technology to non-invasively measure absolute hematocrit help determine the optimal weight in real time. Use of can be repeated with every dialysis treatment no extra cost. With Crit-line, assessed each treatment. Changes RPV <-3%/hr classified as Profile A (volume overloaded), >-3% <-6.5%/hr B (the best compromise high ultrafiltration rate prevention intradialytic symptoms) >-6.5%/hr C (risk volume depletion symptoms). Heart failure (HF) among patients predicts early mortality. These difficult manage have admission fluid overload. In this retrospective cohort study inpatient ESRD patients, we compared outcomes HF vs evidence heart failure.All used blood device, Crit-Line. Outcomes interest included: removal, attaining weight, Intradialytic hypotension, hospital readmissions Patient characteristics were across non-HF using Chi-squared tests for categorical variables two-sample t-tests numerical variables, which all normally distributed. our sample size, adequately powered detect medium large effect sizes (Cohen’s d =0.61) w=0.30 0.35) 87 met inclusion criteria, whom 49 (56%) (had EF <=50 or CHF diagnosis) 38 (44%) not. Using Monitor, higher percentage able attain expected end encounter (60% 46%, p=0.36). The incidence IDH first last session was not significantly different groups, although it slightly patients.
