Fever of hemodialysis appeared and Prevention

Causes and Prevention of hemodialysis in hemodialysis patients with uremia fever is the main place of treatment, with the removal of toxins from the body, loss of physical and other gatherings significantly improved after dialysis. However, hemodialysis patients sometimes chills, fever and other symptoms, which is what causes it, how should we prevent it?

Hemodialysis causes fever appears:

1. pyrogenic reactions: caused mainly by endotoxin. Pollution dialysate side mainly from dialysis water and dialysate concentrate configuration, theoretically toxins within the macromolecules, they can not enter the blood through the dialysis membrane, but its degradation products or due to incomplete dialysis membrane area can enter the blood; blood dialysis membrane side of the pollution from the dialyzer, the blood line and rinsed with saline. The use of high-flux dialyzers has the advantage of a higher clearance in molecular poisons.

2. infection factors: patients with existing infections such as tonsillitis, dialysis can lead to the spread of infection and fever; dialyzer, if disinfection is not strict, will increase the chance of infection fever; deep venous catheter, the occurrence of catheter-related infections , can cause chills, fever.

3. transfusion, infusion reactions;

4. Heparin allergy can;

5. dialyzer residual disinfectant and cleaning agent;

6. The dialysate high temperature;

Preventive measures and treatment methods:

1, during dialysis, fever, chills, nurses and physicians should be promptly reported.

2, double-check before dialysis dialysis supplies packaging is intact and disinfection validity; strict aseptic; Dialysis and pipes properly rinsed before use, strict disinfection after use.

3, to give patients high fever Bupleurum intramuscular, non-steroidal anti-inflammatory drugs or physical cooling ice packs and other cooling treatment; severe dialysis should be promptly terminated.

4, unexplained fever and / or chills, should endotoxin content and disinfectant residual amount of dialysis water or reuse water testing. Endotoxin-related fever is generally used antipyretics symptomatic treatment.

5 suspected infectious fever, blood in blood cultures fever checks, while use broad-spectrum antibiotics.

Causes of fever that occur during dialysis diverse, different methods of heat treatment are not the same reason. When a fever, you should carefully analyze the reasons, symptomatic treatment in order to better control the disease.
