Viral hepatitis A, B, C, D, E, G and so on. Viral Hepatitis is mostly in type B and C in hemodialysis patients, accounting for 95-100% of all viral hepatitis, so we focus on these two diseases.
The following measures have been proven effective in controlling viral hepatitis.
Minimise or no blood transfusion. Before the middle of the eighties, the treatment of anaemia anaemia mainly depended on blood transfusion. In that period, the rate of hepatitis infection in hemodialysis patients was very high. It was reported that infection rates of various hepatitis viruses reached 20-80% in foreign countries. With the advent of erythropoietin, more and more patients with uremia use erythropoietin to treat anemia, so that blood transfusions are no longer needed. At present, the prevalence of hepatitis infection in hemodialysis patients in all countries is significantly lower than before the advent of erythropoietin. Therefore, no blood transfusion or use of blood products is the most effective way to prevent hepatitis virus infection.
The premise of non-blood transfusion is that the patient's condition does not require blood transfusion, and all uremic patients should be encouraged to use erythropoietin to treat anemia and stabilize hemoglobin at the target value (110g/L-120g/L). If you have severe anaemia or have an acute bleeding disorder, you should still receive blood transfusions to avoid life-threatening injuries.
According to the international guidelines on hepatitis virus infection, hepatitis B patients must not reuse the dialyzer. Patients with hepatitis C infections should use dialyzers as soon as possible and must be reused. The infection control procedures and measures must be strictly followed.
To increase awareness of prevention, new patients should routinely check for infections of various infectious diseases when they enter dialysis treatment. If there is hepatitis virus infection, it should be actively treated.
Each dialysis center must have a dedicated treatment room and a contaminant treatment room. After each shift or daily dialysis, the dialysis machine was carefully disinfected according to procedures, and the bed sheets were changed. After the completion of the daily dialysis work, the dialysis room was completely disinfected on the floor and tabletop. Although hepatitis B virus has strong resistance to the outside world, conventional disinfection methods such as thermochemical disinfection, high-pressure steam, chlorine-containing preparations, ethylene oxide, glutaraldehyde, peracetic acid, and iodophor etc. Hepatitis virus also has a good inactivation effect.
Vaccination has confirmed that the successful vaccination of the hepatitis B vaccine can protect the vaccinated person from hepatitis B infection, thereby reducing susceptible inpiduals. So if hepatitis B is negative, you should receive hepatitis B vaccine. The above measures prevent the spread of viral hepatitis from three aspects: cutting off the transmission route, managing the source of infection, and reducing the risk of infection.
