Bedside dialysis is also known as continuous bedside hemodialysis. The cost varies according to different hospitals and different regions, about 5000-7000 RMB. Bedside dialysis is suitable for patients with critical conditions or serious complications and unstable blood circulation. Bedside dialysis can not only remove toxins and excess water from the body, but also has obvious advantages: 1, bedside dialysis is supervised by specialized nurses, which can monitor the patient’s condition in a timely manner; 2, the formula of replacement fluid can be adjusted at any time according to the results of the examination, such as electrolyte examination results, which can better correct the internal environment disorder; 3, because of the longer duration, the dialysis effect is more gentle and gentle, and the impact on blood circulation is not large, which will not cause the patient’s blood pressure to be sudden, and will not cause the patient’s blood pressure to be unstable. Because of the long duration, the dialysis effect is mild and gentle, which has little effect on blood circulation and does not lead to a sudden drop in blood pressure.
