What is the cause of hypotension during dialysis?

Dialysis hypotension is the result of an inadequate cardiovascular response to the reduction in blood volume that occurs when a large volume of water is removed during a short period of time.

How can dialysis prevent hypotension?

Prevention

1. Avoiding meals during dialysis.
2. Avoid taking blood pressure medications just prior to dialysis or consider switching times.
3. Avoiding weight gain between successive dialysis treatment, as the less fluid that needs to be removed, the easier it is for the circulatory system to maintain blood pressure.

How is intradialytic hypotension treated?

How should patients with intradialytic hypotension be managed?

1. Place the patient in the Trendelenburg position.
2. Reduce the ultrafiltration rate or stop ultrafiltration.
3. Infuse boluses of 100 mL of 0.9\% isotonic saline as necessary (first choice infusate).

Does dialysis cause low blood pressure?

Low blood pressure (hypotension) is one of the most common side effects of haemodialysis. It can be caused by the drop in fluid levels during dialysis. Low blood pressure can cause nausea and dizziness.

What is the management of hypotension?

Drink more water. Fluids increase blood volume and help prevent dehydration, both of which are important in treating hypotension. Wear compression stockings. The elastic stockings commonly used to relieve the pain and swelling of varicose veins can help reduce the pooling of blood in your legs.

What happens if your blood pressure is too low for dialysis?

Low blood pressure during dialysis increases risk of clots, according to Stanford-led study. A sudden drop in blood pressure while undergoing dialysis has long vexed many kidney patients. Side effects associated with this situation over the long term range from stroke to seizure to heart damage to death.

Is hypotension a complication of dialysis?

Aims: Hypotensive episodes are a major complication of hemodialysis. Hypotension during dialysis could be directly related to a reduction in blood volume or to a decrease in cardiovascular activation as a response to decreased cardiac filling.

What is considered severe hypotension?

In severe cases, low blood pressure can be life-threatening. A blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic) is generally considered low blood pressure.
