What is a pyrogenic reaction in dialysis?

Pyrogenic reactions (PR) are a well-recognized complication of hemodialysis and have been associated with dialyzer reuse, high-flux dialysis, and bicarbonate dialysate. However, the roles of bacteria and endotoxin in dialysate for producing PR are not well defined.

What are the causes of fever during dialysis?

The most common causes of fever (independent of reuse or dialysis procedure) in dialysis patients are three types of infection: 1) of the bronchopulmonary system, 2) of the urinary tract, and 3) access related infections. These “big three” comprise the vast majority of causes of fever in dialysis patients (1-3).

What is the most common complication during hemodialysis?

A drop in blood pressure is a common side effect of hemodialysis. Low blood pressure may be accompanied by shortness of breath, abdominal cramps, muscle cramps, nausea or vomiting.

What happens if you are allergic to dialysis?

Mild symptoms include itching, burning sensation at the access site, urticaria, flushing, cough, sneezing, wheezing, abdominal cramps, diarrhoea, headache, back and chest pain, nausea, vomiting, fever and chills. More severe reactions lead to dyspnoea and hypotension, potentially resulting in cardiac arrest and death.

What are symptoms of pyrogenic reaction?

Chills (75 percent), nausea and/or vomiting (30 percent), and fever (90 percent) were the most common signs and symptoms, with mean times of onset after starting dialysis of 1.1, 1.6, and 3.6 hours, respectively.

What causes pyrogenic reaction?

The cause of these reactions was traced to an increase in endotoxin contamination of the tap water used to prepare dialysate, possibly caused by an increase in the algae levels in the local water source.

Is fever normal for a dialysis patient?

Fever in haemodialysis patients is usually attributed to infection, with less frequent causes including malignancy and autoimmune disorders [1]. Sometimes, fever persists despite empirical treatment, and investigations towards the above mentioned diagnoses fail to reveal the cause.

Is fever common with dialysis?

Fever in patients on dialysis is usually due to common respiratory or digestive infections, and when chills accompany fever during dialysis sessions, an endovascular infection must be suspected. Uncommonly, autoimmune diseases or malignant tumors may also be associated with fever.

What are the contraindications of hemodialysis?

Absolute contraindication to hemodialysis is the inability to secure vascular access, and relative contraindications include:

• Difficult vascular access.
• Needle phobia.
• Cardiac failure.
• Coagulopathy.

What is the procedure for hemodialysis?

Hemodialysis is a procedure where a dialysis machine and a special filter called an artificial kidney, or a dialyzer, are used to clean your blood. To get your blood into the dialyzer, the doctor needs to make an access, or entrance, into your blood vessels. This is done with minor surgery, usually to your arm.

How can you be allergic to dialysis?

Allergic reactions are commonly caused by food, medication, pollen, animal dander, insect stings, and latex. But for dialysis patient, an often overlooked trigger is the dialyzer. For hemodialysis patients, an allergen that reportedly causes allergic reactions during dialysis is the synthetic dialyzer membrane.

Can you be allergic to dialysis solution?

Dialysis-associated allergic reactions are classified as Type A or Type B reactions. Type A reactions typically occur within 5–20 minutes of dialysis initiation whereas Type B reactions are usually delayed and occur later in the session.

What causes hemolysis in dialysis patients?

If several patients develop hemolysis in a single dialysis unit, contamination of the dialysate, faulty tubing, and altered dialysate osmolality should be suspected. A systematic assessment of the potential causes is imperative to avoid recurrent hemolysis during a subsequent HD session (Figure 2).

What are the risks and side effects of hemodialysis?

Other risks and side effects of hemodialysis may include anemia, difficult sleeping, heart conditions, or cardiac arrest. Many of these side effects are due to the fluid and mineral imbalances that dialysis can cause. Other than the risk of infection, common peritoneal dialysis side effects are slightly different from those of hemodialysis.

How fast does dialysis cause hemorrhagic shock?

With a typical dialysis blood flow of 300–500 ml/min, hemorrhagic shock ensues within minutes (after loss of 30%–40% of total blood volume) (62).

What causes pyrogenic reactions in dialysis?

Dialysis-Associated Pyrogenic Reactions Gram-negative bacterial contamination of dialysis water or components of the dialysis system (water, dialysate, water used for reprocessing) can cause pyrogenic reactions.
