Predicting factors of intradialytic hypotension in the last half of hemodialysis therapy

Abstract Background Intradialytic hypotension (IDH) is one of the most frequent complications hemodialysis. IDH alters a patient’s quality life and has strong association with mortality. mainly occurs when ultrafiltration during hemodialysis exceeds pace plasma refill. Ultrasonography been used to evaluate intravascular volume status. We evaluated between baseline laboratory data or ultrasound findings latter half session. Methods Sixty-two patients who underwent were enrolled in this study. The peak early mitral inflow wave velocity (peak E-velocity), inferior vena cava (IVC) dimensions, number B-lines estimated at two time points (just after start midpoint session). compared parameters without throughout session (non-IDH group) only (IDH group). Results Of 62 study participants, 28 non-IDH group, 16 group. serum sodium level was significantly lower group (135 ± 4 mEq/L) than (138 ( P = 0.015). rate decrease E-velocity higher (0.33 0.13) (0.24 0.14) 0.037). best cutoff point 137 mEq/L, sensitivity 68.8% specificity 64.3%. area under receiver operating characteristic (ROC) curve 0.71. 0.295, 73.3% 71.4%. ROC Conclusions A low an may be related intradialytic Careful observation needed whom below mEq/L over 0.295.
