Acute Renal Failure refers to the kidneys lose their function in a very short time. It can cause a series of complications, in which some may threaten the patients’ life seriously. Therefore, it is very important for the patients to know the complications so as to take prevention in time.
Infection is the commonest and most severe complication in Acute Renal
Failure, especially those caused by trauma. The common infections include
urinary tract infection, sepsis, pulmonary infection, which can make the
patients’ survival rate decline greatly.
2. Cardiovascular diseases
Heart failure, cardiac arrhythmia, hypertension, pericarditis and even
cardiac tamponade are the common complications of Acute Renal Failure. Cardiac
arrhythmia mainly presents atrial premature beat, atrial fibrillation. The main
causes of cardiac arrhythmia consist of electrolyte disturbance, like
hyperkalemia, hyponatremia, and acidosis and so on. Hypertension and heart
failure result from water-sodium retention. The patients often have difficulty
in breath and other symptoms of acute pulmonary edema.
3. Electrolyte disturbance
(1)Hyperkalemia can lead to heart arrest, which is the most dangerous
complication of Acute Renal Failure. Moreover, the patients also have
hyponatremia, hyperphosphatemia and hypocalcemia. The main cause of hyperkalemia
is oliguria or anuria. Moreover, serious infection, bleeding or hemolysis also
can lead to hyperkalemia. In addition, hyponatremia, hypocalcemia and acidosis
aggravate hyperkalemia to some extent. Hyperkalemia is the main death cause for
the patients with Chronic Renal Failure. Therefore, the patients should pay more
attention to it and adopt treatment in time.
(2)Hyponatremia in Acute Renal Failure is related to causes. First, acute
tubula r necrosis can cause oliguria and retention of water and sodium, which
can lead to diluent hyponatremia. Second, urmic toxin and acidosis can cause
vomit and nausea or body fluid loss related to trauma or burn, which can further
4. Nerve system
The complications of nerve system mainly present headache, drowsiness,
hyperspasmia, coma or epilepsia. In severe case, those complications may
threaten the patients’ life.
5. Digestive system
The patients with Acute Renal Failure often have nausea, vomit, abdominal
distension, gastrointestinal bleeding and other symptoms of digestive system.
About 10~40% of the patients with Acute Renal Failure are complicated with
gastrointestinal bleeding, among which 20~30% may die of it.
6. Blood system
For the decline in renal function, less hemopoietin is secreted thus causing
As Acute Renal Failure can cause so many complications and even threaten the
patients’ life, the patients should take prevention in advance so as to avoid
their happening. If you want to know more information about Acute Renal Failure
