Complications Coming From Hemodialysis

2012-11-26 17:06


Around 20% of patients on hemodialysis would suffer from spasm due to ultrafiltration rate and low-solution dialyzer.

How to deal with spasm?

Lowering ultrafiltration rate could get spasm improved. Injecting isotonic sodium solution or 50% of dextran are all helpful for treating convulsion. Pain induced by convulsion can be relieved by taking diazepam, but also, low blood pressure might attack as a result.

Dialysis imbalance syndrome

Nonspecific symptoms attacked during or after hemodialysis, like nausea, vomiting, fatigue, headache and disability etc. Those symptoms can be life-threatening, which include coma, twitch and arrhythmia etc. It is believed that abrupt change of solute concentration of central nerve system and pH value account for the occurrence of dialysis imbalance syndrome.

For those who begin to receive hemodialysis just now, reduce the change of osmotic pressure could improve this situation. If symptoms become really serious, like serious headache or convulsion, then hemodialysis should be stopped right now.

Low blood sugar

Insulin dosage might be reduced when the day those patients are planning to receive hemodialysis. The glucose concentration should not exceed 5.55mmol/L in diabetics.


ESRD impairs platelet function and changes capillary permeability, and thus, lead to hemorrhage.

Hemodialysis could partially correct platelet dysfunction and improve capillary permeability. However, if heparin is adopted for a long time, the incidence rate of bleeding in patients on hemodialysis increases.


Hemolysis might attack during the process of HD. A bunch of reasons can lead to the attack of hemolysis, like type of dialysis.


Anoxia, also known as oxygen deficiency, is associated with properties of dialyzer and dialysis membrane. To patients with cardiopulmonary insufficiency or have a strong response to dialysis membrane who develop serious anoxia, oxygen uptake is needed.
