What is dialysis cramp? How to prevent it?

In clinical practice, people often experience cramps when undergoing hemodialysis. In fact, there are certain reasons for cramps during dialysis, which the following article will introduce to you.

Causes of dialysis cramps:

1. Improper water removal, water removal speed is too fast, water removal volume is too large, and water removal below the basic weight;

2. Electrolyte abnormalities, such as low sodium dialysate. In addition, metabolic acidosis during hemodialysis is corrected in a timely manner, free calcium is reduced, and muscle excitability is enhanced;

3. Low blood pressure;

4. Poor nutritional status and inability to tolerate dehydration.

Prevention and emergency treatment of dialysis cramps:

1. Change body position in time to avoid cold stimulation and reduce muscle excitement.

2. Slow down water removal and reduce blood flow.

3. Local hot compress and local massage.

4. If blood pressure is normal, lower limb convulsions can cause the patient to sit up with both feet flat on the ground.

5. Rehydrate with fluids, such as saline.

6. Hyperosmotic fluid 10% NaCI injection or 50% glucose injection.

7. When preparing the dialysate, pay attention to the concentrations of Na+ and Ca2+.
