Indications for emergent dialysis

Acidosis is a term used to describe an imbalance of acids and bases in our body. When this is unable to be corrected with medicine or it is severe, urgent dialysis may be needed.
An imbalance of your electrolytes, predominately potassium at an elevated level, may also prompt urgent dialysis. Initially medication is used to correct this elevated potassium but can fail, especially if your not making urine.
There are multiple medication overdoses, toxic medication levels or toxic ingestions such as antifreeze poisoning that may require dialysis to remove them from the blood. 
When there is an imbalance in fluids, meaning your body fluid intake is higher than what your body is putting out (either urine, stool, or sweat) one may develop positive fluid balance. 
A positive fluid balance when someone is hospitalized, especially if critically ill, is known to increase the risk of death. Additionally one may develop breathing issues with a positive fluid balance. 
Often times diuretics are used to augment urine production. If these fail to yield adequate results, dialysis may be used to maintain a balance of fluids in an attempt to prevent these aforementioned complications. 
Our kidneys remove toxic build up from our blood that is produced by our bodies on a daily basis. If the kidneys don’t work or work inadequately then the toxins can build up causing confusion and coma. At this point dialysis may be needed.
