What is Dialysis?

Dialysis is a medical treatment that replicates the kidney's essential functions when they can no longer perform adequately due to failure or severe chronic disease. It purifies the blood by removing waste products, excess fluids, and toxins, thereby maintaining a healthy balance of electrolytes and preventing dangerous buildups that can lead to serious health issues.

In what situations would a patient require dialysis therapy?

Dialysis therapy is needed when a patient’s kidneys cannot filter waste, toxins, and excess fluids from the blood effectively. Situations requiring dialysis include:
End-Stage Renal Disease (ESRD): When chronic kidney disease (CKD) progresses to stage 5 and kidney function is below 15%, dialysis is necessary to replace lost kidney function.
Acute Kidney Injury (AKI): Sudden kidney failure from severe injury, dehydration, or toxic exposure may require temporary dialysis until kidney recovery.
Life-Threatening Electrolyte Imbalances: Dangerous levels of potassium, sodium, or acids in the blood that cannot be managed by other treatments.
Severe Fluid Overload: When excess fluid in the body causes complications like pulmonary edema or heart failure.
Uremia: High toxin levels in the blood leading to symptoms like nausea, confusion, pericarditis, or seizures.

What are the functions and processes of the kidneys?

The kidneys filter waste and excess fluids from the blood, regulate electrolyte levels, maintain acid-base balance, and produce hormones that control blood pressure and stimulate red blood cell production. These functions are achieved through processes like filtration, reabsorption, secretion, and excretion within the nephrons.

Types of dialysis

Dialysis is a treatment that replicates some of the functions of healthy kidneys in people with kidney failure. There are two main types of dialysis

Hemodialysis (HD)

In-Center Hemodialysis: Performed at a dialysis center, usually three times a week for 3-5 hours per session. A machine filters wastes, salts, and fluid from the blood.

Home Hemodialysis: Similar to in-center HD, but performed at home. It allows for more flexibility and can be done more frequently with shorter sessions.

Peritoneal Dialysis (PD)

Continuous Ambulatory Peritoneal Dialysis (CAPD): Performed manually throughout the day without a machine. The patient exchanges dialysis fluid four to five times a day.

Automated Peritoneal Dialysis (APD): Uses a machine (cycler) to perform exchanges, usually at night while the patient sleeps.

Both types of dialysis require training and regular monitoring by healthcare professionals to ensure the patient receives effective treatment.

Dialysis procedure

Dialysis filters waste and excess fluid from the blood. In hemodialysis, blood is drawn from the body, cleaned in a machine, and returned. In peritoneal dialysis, a cleansing fluid is introduced into the abdominal cavity to absorb waste, then drained. Both procedures help manage kidney failure.
