We sought to identify a potential dependence of methadone’s removal on dialysate flow rate. If the model could detect such a dependence, it would serve as a test of the model’s sensitivity to detect a mechanism-based change. WebHowever, unlike IHD, the dialysate flow rates (typically 0.5 to 2 L/hr, or 8-34 ml/min) in continuous hemodialysis are significantly slower than the blood flow rates (typically 100-200 ml/min), resulting in complete or near-complete saturation of the dialysate. Small molecules are preferentially removed by diffusion-based methods. library uco
