Show Notes
Contributor: Taylor Lynch, MD Educational Pearls: When a patient who missed dialysis presents to the emergency department, our clinical concern is who needs to be admitted to the hospital for emergent dialysis and who can wait for their next regularly scheduled session.
Dialysis sessions typically occur on Monday, Wednesday, and Friday, or Tuesday, Thursday, and Saturday.
Acronym for indications for emergent dialysis: AEIOU
Acidosis
Patients may have an underlying cause for acidosis such as sepsis or DKA.
Treat the underlying cause, but if the acidosis is unable to be corrected, the patient needs dialysis.
Electrolytes
Most commonly elevated is potassium.
In general, dialysis patients tend to have higher potassium levels, so don't just treat the number.
Look for potassium greater than 6.5 or if EKG changes are present.
Ingestion
Intoxication with substances such as Lithium, Ethylene Glycol, Methanol, Salicylates.
Overload
Patients may present with evidence of fluid overload such as new oxygen requirement or pulmonary edema.
If they are making urine, treat with diuretics, but if unresponsive to medical therapy, they will require dialysis.
Uremia
Build-up of nitrogenous waste products in the blood, which is indicated by an elevated BUN.
Patients may develop complications such as altered mentation or pericardial effusions and subsequent cardiac tamponade.
Keep in mind creatinine itself is not an indication for emergent dialysis.
Serves as a surrogate marker of kidney function.
Can be high or low depending on muscle mass or kidney filtration, and the patient may or may not need dialysis.
