Sustained Low-Efficiency Dialysis

SLED is a slow and continuous form of dialysis usually used for critically ill patients. It gently removes waste and excess fluid over a longer period, putting less stress on the body. This method helps maintain stable blood pressure and is often used in intensive care settings under close monitoring.

Frequently Asked Question's About SLED

What is sustained low-efficiency dialysis (SLED)?

Sustained low-efficiency dialysis is a slower form of dialysis that is performed over a longer period than conventional haemodialysis. It is generally used in critically ill patients who may not tolerate rapid changes in fluid or waste removal.

Who may need SLED treatment?

SLED may be considered for patients with severe kidney dysfunction who are critically ill, particularly when blood pressure or overall condition makes standard dialysis more difficult to tolerate. The critical care and nephrology teams decide whether it is appropriate for the individual patient.

How is SLED different from regular hemodialysis?

SLED runs at lower blood and dialysis-fluid flow rates and usually continues for several hours. This slower approach allows fluid and waste products to be removed more gradually, which can be useful for patients who need gentler dialysis support.

Can SLED be used for patients with unstable blood pressure?

In selected critically ill patients, SLED can provide slower fluid and waste removal and may be better tolerated than conventional intermittent haemodialysis when blood pressure is unstable. The dialysis prescription is adjusted according to the patient's condition and clinical requirements.

How is a patient monitored during SLED?

Patients undergoing SLED require close monitoring of blood pressure, heart rate, fluid balance, blood chemistry, and other clinical parameters. The medical team adjusts the dialysis settings and treatment duration according to the patient's response and changing condition.
