What about dialysis for infectious disease patients

According to the principle of hemodialysis, the dialysis machine only plays the role of a "stent" and does not touch the patient's blood. This means that there is no patient blood contamination of the machine during normal operation, and there is no possibility of patient-to-patient cross-infection. The American APIC "Guide to the Elimination of Infections in Hemodialysis" (2010) wrote that HIV-infected patients do not have to be separated from other patients or dialysis machine dedicated, and hemodialysis patients prevention of infection and control program 12 articles did not mention that hemodialysis patients with infectious diseases must be dedicated to dialysis. Daily work strictly implement the dialysis machine and pipeline effective disinfection, isolation of patients zoned treatment, disposable dialyzers and other non-reuse, strict hand hygiene and good medical waste disposal and other integrated prevention and control measures. Provides an Italian "Evaluation of sterilization and isolation of dialysis machines" literature as a basis. The embarrassment of patients with multiple infections. In practice, not only will we encounter patients with hepatitis B, hepatitis C, and AIDS, but we will also see patients with hepatitis B+HIV, hepatitis B+Hepatitis C, hepatitis B+Syphilis+HIV, and other co-infections, which exist in a small number of patients, making it difficult for many hospitals to specialize in dialysis machines. Especially for county-level and below hospitals, the lack of funds, few dialysis machines, and insufficient patient resources lead to low frequency of dialysis machine use and waste of resources. Window period problem. Whether it is hepatitis B, hepatitis C, syphilis or AIDS patients, there is a window period, and in the window period of the patient is not detected, dedicated machine dialysis is meaningless. Dialyzer problem. Now the domestic mostly use FX series dialyzer, its dialysis membrane membrane pore average is only 3.3 nanometers, compared with the diameter of the virus is 18~350 nanometers, the diameter of HCV>30 nanometers, the virus can't pass through the dialysis membrane to pollute the internal waterway of the dialysis machine. It is impossible for the midstream dialyzer to cause cross-infection to the upstream dialysate pipeline if membrane breakage occurs during use. Moreover, there is no difference between the disinfection of pipelines for patients with blood-borne infectious diseases and those with non-blood-borne infectious diseases, and the problem can be solved by stopping the operation of the dialyzer and disinfecting it in a timely manner. The current norms and standards have been used for more than five years, and now the hospitals in the implementation of disinfection and isolation system has been qualitatively improved, dialysis technology has improved a lot, dialyzer in the unconditional reuse of all disposable use, which has been restricting the clinical work, become an obstacle to the development of dialysis.
