| [ Summary ] | Adequate fluid management is important in improving prognosis in patients undergoing dialysis. However, in the current era, conventional indicators for fluid management are not applicable to a rapidly increasing aging population that includes a large percentage of undernourished patients with a high prevalence of cardiovascular diseases. Body fluid volume is closely associated with a patient's nutritional status; thus, it is difficult to assess fluid balance in patients undergoing dialysis. Multi-frequency bioelectrical impedance analysis (MFBIA) is a clinical method of fluid and nutritional management. Among the nutritional indicators that can be evaluated using MFBIA, the phase angle (PhA) has been drawing attention because it may potentially suggest the presence of sarcopenia and frailty at an early stage in elderly patients undergoing dialysis. The ratio of total body water to fat-free mass combined with the PhA and blood pressure status during dialysis can reflect the patient's clinical symptoms. Thus, these parameters are considered useful indicators to ensure adequate fluid management in patients undergoing dialysis and stable dialysis. | |
