ACUTE
HEMODIALYSIS TREATMENT
bbraun
In-hospital hemodialysis is a medical procedure using a machine to filter waste and excess fluid from the blood when the kidneys are failing. Blood is taken from the body through tubes, passes through a filtering unit (dialyzer) with a semi-permeable membrane, and then returns to the body. This treatment is provided in hospital settings for patients with acute kidney failure or severe complications, while other patients may use dialysis centers or home units for chronic conditions.

The Process

  1. Vascular Access:
    A minor surgery creates a vascular access site, usually in the arm, to provide a way for blood to enter and exit the body during treatment. 

  1. Blood Circulation: 

Blood travels through tubes to the dialyzer, a machine with a filter called a dialyzer.

  1. Filtering: 

Inside the dialyzer, the blood is separated from a special cleansing fluid called dialysate by a semi-permeable membrane.

  1. Waste Removal: 

Waste products and excess fluid move from the blood across the membrane into the dialysate. 

  1. Return of Blood: 

The cleaned blood is then returned to the body through a separate set of tubes. 

Why In-Hospital Hemodialysis is Used

Acute Kidney Failure: In-hospital treatment is often necessary for patients with sudden kidney failure who require urgent and intensive care.


Complications: Patients may require hospital hemodialysis due to complications of chronic kidney disease or dialysis access issues that cannot be managed at a clinic or home.

Types of In-Hospital Care

Acute Intermittent Hemodialysis: Provided in the hospital ward, this is a common form of treatment for acute renal failure.


Continuous Renal Replacement Therapy (CRRT): This is a slower, more continuous form of dialysis used for patients in the Intensive Care Unit (ICU) who are critically ill.
