What causes hypotension during dialysis?

What causes 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.

What are some complications of dialysis?


  • Low blood pressure (hypotension). A drop in blood pressure is a common side effect of hemodialysis.
  • Muscle cramps. Although the cause is not clear, muscle cramps during hemodialysis are common.
  • Itching.
  • Sleep problems.
  • Anemia.
  • Bone diseases.
  • High blood pressure (hypertension).
  • Fluid overload.

How do you manage intradialytic hypertension?

Prevention and treatment of intradialytic hypertension may include careful attention to dry weight, avoidance of dialyzable antihypertensive medications, limiting the use of high calcium dialysate, achieving adequate sodium solute removal during hemodialysis, and using medications which inhibit the rennin-angiotensin- …

What is the treatment for hypotension during dialysis?

Intradialytic hypotension can be challenging to treat, especially in patients with multiple risk factors. For most patients who experience a drop in blood pressure, small amounts of intravenous fluids are given (usually a common fluid-like normal saline given in a small bolus of 250 ml or so).

How do you keep blood pressure from dropping during dialysis?

How to Prevent Blood Pressure Drops

  1. Be sure your dry weight is right. If you work out or eat more so you gain “real” weight, tell your care team and ask for a higher dry weight.
  2. Be sure the machine is set correctly.
  3. It’s not necessarily you.
  4. Consider home dialysis.

How do you treat DDS?

Once DDS develops, treatment is directed to reduce intracranial pressure with mannitol and hypertonic saline [3]. Our patient did well with the administration of 3% hypertonic saline and mannitol with full neurological recovery.

Why do dialysis patients turn dark?

Many reported cases of discolored skin, or hyperpigmentation, happen to people with ESRD. One cause of skin discoloration is related to pigments called urochromes being retained in the skin. Normally these are excreted by healthy kidneys. Patients with this condition tend to have a grayish, almost metallic color skin.

How is intradialytic hypotension prevented?

Summary: Adequate prescription and frequency of dialysis treatments, limiting dietary and dialysate sodium, ultrafiltration profiling, automatic biofeedback-controlled dialysis, avoidance of acetate, and cool temperature dialysate may be effective strategies to reduce IDH.

What is Intradialytic hypertension?

Intradialytic hypertension is an increase in blood pressure from pre to post hemodialysis that has recently been identified as an independent mortality risk in hypertensive hemodialysis patients.
