Episode 86 - Emergency Management of Hyperkalemia (2022)

General Approach to Emergency Management of Hyperkalemia

Placethe patient on a cardiac monitor, establish IV access and obtain an ECG

If the patient is stable, consider the cause and rule out pseudohyperkalemia (from poor phlebotomy technique, thrombocytosis or leucocytosis) and repeat the potassium to confirm hyperkalemia.

Stabilize the cardiac membrane with Calcium Gluconate 1-3 amps

(or Calcium Chloride 1 amp ifperi-arrest/arrest)if:

a) K>6.5 or

b) wide QRS or

c) absent p waves or

d) peri-arrest/arrest

Drive K into cellswith 2 amps D50W + Regular Insulin 10 units IV push

followed byB-agonists 20mg by neb or 8 puffs via spacer if:

a) K>5 with any hyperkalemia ECG changes or

b) K>6.5 regardless of ECG findings

Eliminate K through the kidneys and GI tract whileachieving euvolemia and establish good urine flow

Normal Saline IV boluses ifhypovolemia

Furosemide IVonlyif hypervolemic

PEG 3350 17g orally for alert patients remaining in your ED for prolonged period of time

Dialysis for arrest, peri-arrest, dialysis patient or severe renal failure

Monitorrhythmstrip,glucose at 30 mins, K and ECG at 60 mins

(Video) Emergency Management of Hyperkalemia (Part 1)

and repeat as needed until the K is below 6, ECG has normalized and/or dialysis has been started

Update 2017:A recent retrospective study suggested that in patients with renal insufficiency and hyperkalemia, administration of 5 units of insulin rather than 10 units significantly decreased the incidence of hypoglycemia while correcting potassium to a similar degree. For ED patients with hyperkalemia and renal insufficiency, consider either lowering the initial dose of insulin from 10 units to 5 units, or ensuring that 2 amps of D50W (rather than 1) is administered concurrently to avoid hypoglycemia. Abstract

The ECG in Emergency Management of Hyperkalemia

The ECG changes associated with hyperkalemia do not always happen in a step-wise fashion with predictable serum potassium levels. Although it is generally true that higher levels of potassium correlate withprogressive ECG changes, the more acute the hyperkalemia the more likely the ECG changes occur. It is possible for a hyperkalemic patient to progress rapidly from a normal ECG to ventricular fibrillation.

The classic ECG progression in hyperkalemia

  1. Peaked T wave(K approx 5.5-6.5)

Peaked T waves reflect faster repolarization of the myosite. A sensitive sign is if the amplitude of the T exceeds the amplitude of the R. This distinguishes peaked T waves of hyperkalemia from hyperacute T waves ofearly MI which tend to have a broader base T wave.

Peaked T waves of Hyperkalemia. Note the amplitude of the T exceeds the amplitude of the R. Care of Life in The Fast Lane blog.

Episode 86 - Emergency Management of Hyperkalemia (3)

Hyperacute T waves of early MI. Note the broad-based T waves in the anterior leads to help distinguish from peaked T waves of hyperkalemia. Care of Dr. Smith’s ECG blog.

  1. Prolonged PR interval and flattening ordisappearanceof the P wave (K approx 6.5-7.5)

The resting potential of myosite becomes more positive which slows depolarization.

Episode 86 - Emergency Management of Hyperkalemia (4)

Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.

  1. Widening of the QRS

The increasingly positive membrane potential leads to progressively slowed depolarization and widening of the QRS.

Episode 86 - Emergency Management of Hyperkalemia (5)

Widened QRS in severe hyperkalemia (Care of Dr. Melanie Baimel)

  1. Sine Wave: pre-terminal rhythm

As the depolarization slows, the widening QRS begins to merge with the T wave. This is a pre-terminal rhythm which can deteriorate rapidly into Ventricular Fibrillation.

Episode 86 - Emergency Management of Hyperkalemia (6)

Sine wave in severe hyperkalemia, a pre-arrest rhythm.

Hyperkalemia is the Great ECG Imitator

These ECG findingsare not specific to hyperkalemia alone. Given the broad differential for these ECG changes, hyperkalemia has been dubbed the “Great ECG Imitator”. It is important to consider the patient’s presentation, clinical complaints and trends on the ECG.

PEARL: Hyperkalemia has been known to cause almost any dysrhythmia. Pay special attention to patients in “slow VT” and wide-complex bradycardia and consider treating them empirically as hyperkalemia.

Determine the Causeof Hyperkalemia

First rule out pseudohyperkalemia which accounts for 20% of hyperkalemia lab values.

Pseudohyperkalemia iscaused byhemolyzed sample, poor phlebotomy technique leukocytosis or thrombocytosis.

Then treat the underlying cause:

  • Medications: ACEi, Potassium sparing diuretics, B-Blockers, NSAIDs, Trimethoprim (Septra) and Non-prescription salt substitutes
  • Renal Failure
  • Cell death: Secondary to rhabdomyolysis, massive transfusion, crush or burn injuries.
  • Acidosis: Consider Addison’s crisis, primary adrenal insufficiency and DKA.

PEARL: If hyperkalemia cannot be explained by any other cause and the patient has unexplainedhypotension, draw a random cortisol and ACTH level andgive 100 mg IV solucortef for presumed adrenal insufficiency.

Medications in the Emergency Management of Hyperkalemia

Three main principles

  1. Stabilize cardiac membrane
  2. Shift potassium intracellularly
  3. Eliminatepotassium

There are specific treatments geared at targeting each of these three main principles, which we will discuss below. Unfortunately, there is no clear evidence to guide exactly when to initiate specific treatments for hyperkalemia. Our experts recommend using two factors to guide your management:

  1. Serum potassium level and
  2. ECG

withthe following indications for immediate treatment of hyperkalemia in the ED:

Episode 86 - Emergency Management of Hyperkalemia (7)

Principle 1: Stabilize the cardiac membrane

Episode 86 - Emergency Management of Hyperkalemia (8)

There is no goodliterature to help guide whether calcium gluconate or calcium chloride is better for stabilizing the cardiac membrane in hyperkalemia. The most important difference to remember is that calcium chloride has 3 times more elemental calcium than calcium gluconate (6.8 mEq/10 mL vs 2.2 mEq/10 mL) and has greater bioavailability. However, calcium gluconate has less risk of local tissue necrosis at the IV site. Therefore, if you decide to give calcium gluconate, ensure you are giving sufficient doses of calcium since one amp may not be enough. Threeamps of calcium gluconate are often required to start to see the ECG changes of hyperkalemia resolve. Remember that calcium does not lowerthe potassium level.

Our experts recommend using calcium chloride through a large well-flowing peripheral IV or central line in the arrest or peri-arrest patient. Calcium gluconate is recommended for all other patientsgiven it’s lower risk for local tissue necrosis.

Routine use: 1 gram of 10% calcium gluconate (i.e. 10 ml mixed with 100cc of D5W or NS in a mini-bag) over 5-10 minutes. Repeat as needed to achieve QRS <100msandp waves re-appear.

Arrest or Pre-arrest: Push 1 amp (1 gram) of 10% calcium chloride through a large bore well-running peripheral IV or central line (preferable).Repeat as needed to achieve QRS <100ms and p waves re-appear.

In patients taking digoxinthe traditional teaching is that calcium is contraindicated. The so-called “stone heart” from the administration of calcium in patient with digoxin toxicity has been largely debunked.A small case-controlled study found no mortality differences between 23 patients with hyperkalemia and digitalis toxicity who were treated with calcium and 136 patients who were not.

If digoxin toxicity is suspected in the setting of severe hyperkalemia, our experts recommend giving calcium cautiously, at a slower rate than usual: 1gram of 10% calcium gluconate in 100 cc of D5W or NS over 15-30minutes (rather than 5 minutes).

Principle 2: Shifting potassium into cells:

The choices for shifting potassium into cellsinclude intravenous insulin and glucose, beta-agonists and bicarbonate. The indications for starting insulin and glucose include a K>5 mmol withECG changes or a K> 6.5 mmol regardless of ECG changes. Observational studies have shown that many patients treated with insulin and glucose for hyperkalemia become hypoglycemic when given 1 amp of D50W followed by 10 units of humulin R. Therefore, based on a recent systematic review our experts recommend the following approach to initiating insulin and glucose therapy:

2 amps of D50W followed by 10 units IV humulin R (rapid injection)

Monitor glucose q30 minutes

Repeat K at 60 minutes

Beta agonists are also useful to rapidly shift potassium into cells. They act synergistically with insulin and can lower serum potassium by 1.2 mmol in an hour. Paradoxically, one third of patients will not have the predicted drop in serum potassium, and observational datahas shown a very transient initial rise in potassium up to 0.4 mmol after administration of beta agonists.Therefore, B-agonistsshould NOT be used as mono-therapyandinsulin/glucose be given first. The doses of beta agonists for hyperkalemia are generally higher than what you would use in asthma:

Salbutamol 8 puffs by aerochamber or 20 mg nebulized

Insulin and beta agonists will start to take effect within 15 min with their peak effect being at 60 min.

Pitfall:If B-agonists are given before insulin/glucose they may cause a transient rise in the serum potassium level. Always give B-agonists after insulin/glucose.

Bicarbonate is also known to shift bicarbonate into cells. Our experts do notrecommend the routine use of bicarbonate in the treatment of hyperkalemia. It may have a role to play in a small subset of patients who also have a non-anion gap metabolic acidosis such as those patients with renal tubular acidosis.

Principle 3: Eliminate Potassium

(Video) Emergency Management of Hyponatremia (Part 1)

The kidneys are the main routefor eliminating of potassium. Ensuring euvolemia and appropriate urine output is the mainstay of treatment. Inserting a foley catheter will allow you to monitor urine output. Many patients will be hypovolemic and will need fluid resuscitation with crytalloid. If you need to volume resuscitate your patient, the initial fluid of choice is Normal Saline even though with huge doses hypercholoremic metabolic acidosis can occure. Ringer’s Lactate contains 4mmol/L of potassium, which poses obvious risks of increasing serum potassium if appropriate renal elimination has not started.

There is no role for diuretics in the routine management of hyperkalemia unless the patient is hypervolemic.

Regarding potassium binding agents such as Kayexalate, a 2005 Cochrane review did not show any evidence that they improve potassium levels. There have also been case reports of Kayexalate causing GI necrosis and perforation. Our experts conclude that there is no role for Kayexalate in the ED.

Consider PEG 3350 orally to help eliminate potassium through the GI tract if the patient is likely to stay in your ED for a prolonged period of time.

Given that most patients with hyperkalemia will have some element of renal insufficiency it is important to remember that milk of magnesia and fleet enemas are both contraindicated as they will cause magnesium and phosphate toxicity, respectively.

Episode 86 - Emergency Management of Hyperkalemia (9)Update 2020: As an alternative to Kayexalate, Sodium Zirconium Cyclosilicate (SZC), also an oral potassium binder has shown some benefit as an adjunct in treating acute hyperkalemia in the ENERGIZE trial, with an acceptable safety profile. It is dosed at 10g q8h and causes an average of ~0.2 mM reduction of potassium after 4hrs, and ~0.4 mM reduction of potassium after 24 hrs.

Hyperkalemia in Cardiac Arrest

Based on the principles of treatment and indications discussed above, our experts recommend the following approach to suspected hyperkalemia (based on patient history and rhythm strip) or confirmedhyperkalemia (based on a point of care blood gas) in cardiac arrest in addition to usual ACLS measures:

Push 1 amp calcium chloride in well running peripheral IV or central line and repeat until the QRS is <100ms

Epinephrine 5-20 mcg q2-5 minutes (shifts K intracellularly)

Sodium Bicarbonate 1 amp IV (if suspectsevere acidosis)

Bolus IV NS

Shift potassium with Insulin and Glucose followed by B-agonist

Dialysis

Rebound Hyperkalemia

In cases of cardiac arrest due to hyperkalemia, perform CPR until the hyperkalemia iscorrected. This may be a much longer time than usual. When ROSC is achieved, it will be primarily due to the effects of calcium rather than decreased potassium levels. The effect of calcium can last 20-30min. Since the stabilizing effects of calcium will wear off, you must promptly work on shifting the potassium and enhancing its elimination as described above. Consider repeating the calcium bolus if there are any worsening ECG changes. Repeat serial potassium measurements to monitor for rebound hyperkalemia, which occurs more often than we’d like.

PEARL: the patient in cardiac arrest with hyperkalemia should not be pronounced dead until their potassiumlevel is normalized

Intra-arrest Dialysis

In cardiac arrest, case reports have demonstrated successful ROSCand good neurologic outcomes despite prolonged arrest when dialysis is initiated during CPR to correct hyperkalemia.

Future Directions in Emergency Management of Hyperkalemia

A new potassium binding drug, ZS-9 shows promise in the acute treatment of hyperkalemia and may make it possible to avoid or postpone the most effective therapy, emergency hemodialysis.

FAQs

What is the emergency management of hyperkalemia? ›

The ECG is a mainstay in managing hyperkalemia. Membrane stabilization by calcium salts and potassium-shifting agents, such as insulin and salbutamol, is the cornerstone in the acute management of hyperkalemia. However, only dialysis, potassium-binding agents, and loop diuretics remove potassium from the body.

What is the greatest emergency threat from hyperkalemia? ›

Of all the electrolyte emergencies, hyperkalemia is the one that has the greatest potential to lead to cardiac arrest.

How do you treat hyperkalemia in ACLS? ›

Treatment of Hyperkalemia

Calcium chloride—10% 5 to 10 mL IV over 2 to 5 minutes to antagonize the toxic effects of potassium at the myocardial cell membrane (lowers risk of ventricular fibrillation [VF]).

  • Drugs that prevent the kidneys from losing enough potassium.

When do you give calcium gluconate for hyperkalemia? ›

In patients with a hyperkalemic emergency: If ECG changes present and/or serum potassium >6.5 meq/L: Give calcium gluconate 1000 mg (10 mL of 10% solution) or calcium chloride 500 to 1000 mg IV over two to three minutes to stabilize cardiac membranes.

Why do we give calcium gluconate for hyperkalemia? ›

Calcium (either gluconate or chloride): Reduces the risk of ventricular fibrillation caused by hyperkalemia. Insulin administered with glucose: Facilitates the uptake of glucose into the cell, which results in an intracellular shift of potassium.

Can atropine given in hyperkalemia? ›

Hyperkalemia reduces myocardial excitability, suppresses Sino- atrial node activity, and blocks the conduction at the Atrioventricular node, which eventually attenuates the response to atropine.

How is hyperkalemia treated in pre hospital? ›

Prehospital Care

In the presence of hypotension or marked QRS widening, intravenous bicarbonate, calcium, and insulin, given together with 50% dextrose, may be appropriate, as discussed in Medication.

Water pills (diuretics), which rid the body of extra fluids and remove potassium through urine. Sodium bicarbonate, which temporarily shifts potassium into body cells. Albuterol, which raises blood insulin levels and shifts potassium into body cells.

Why do you give glucose for hyperkalemia? ›

Due to risks of hypoglycemia, some have advocated the use of glucose alone in the treatment of hyperkalemia. The rationale is based on the theory that exogenous glucose stimulates insulin secretion which shifts potassium into the cell.

How is outpatient hyperkalemia treated? ›

Other treatment options for hyperkalemia include IV calcium, insulin, sodium bicarbonate, albuterol, and diuretics. A new drug (patiromer) was recently approved for the treatment of hyperkalemia, and additional agents are also in development.

How quickly can potassium levels change? ›

High potassium usually develops slowly over many weeks or months, and is most often mild. It can recur. For most people, the level of potassium in your blood should be between 3.5 and 5.0, depending on the laboratory that is used.

When do you recheck potassium after hyperkalemia treatment? ›

After initial interventions, potassium should be rechecked within one to two hours, to ensure effectiveness of the intervention, following which the frequency of monitoring could be reduced. Subsequent monitoring depends on the potassium level and the potential reversibility of the underlying cause.

How much insulin do you give for hyperkalemia? ›

Guidelines have traditionally recommended that patients receive insulin 10–20 units with dextrose 25 g when treated for hyperkalemia. We observed that the risk of both hypoglycemia and severe hypoglycemia was lower in patients treated with alternative insulin dosing compared to standard dosing.

Why do you give insulin and D50 for hyperkalemia? ›

Hyperkalemia is a life-threatening condition that requires prompt management in the ED. One of the most common treatment options is the administration of insulin and glucose to help shift potassium into the cell temporarily. Usually this is ordered as 10 units of regular insulin IV and 1 ampule of D50.

How much does 10 units of insulin lower potassium? ›

Insulin 10 units is estimated to lower serum potassium by 0.6–1.2 mMol/L within 15 minutes of administration with effects lasting 4–6 hours (1–3). However, insulin may also induce unwanted effects, such as hypoglycemia (1, 2).

  • a general feeling of weakness or fatigue.
  • nausea and vomiting.
  • muscle pain or cramps.
  • difficulty breathing.
  • heart palpitations.
  • chest pain.

Why salbutamol is given in hyperkalemia? ›

Among the most outstanding drugs with beta-2 effect is salbutamol, which maintains the hypokalemic effect whether administered intravenously or inhaled. It has been used in cases of hyperkalemia, in both children and adults.

How does dehydration cause hyperkalemia? ›

The body becomes dehydrated when it loses more fluids than it consumes. When the body doesn't have enough fluids, it can't process potassium properly, and potassium builds up in the blood, which can lead to hyperkalemia.

What happens to heart rate in hyperkalemia? ›

More serious symptoms of hyperkalemia can include a decreased in heart rate and weak pulse. Severe hyperkalemia can lead to heart stoppage and death. A rapid elevation in potassium level is usually more dangerous than one that rises slowly over time.

When do you give atropine? ›

Atropine is the first-line therapy (Class IIa) for symptomatic bradycardia in the absence of reversible causes. Treatments for bradydysrhythmias are indicated when there is a structural disease of the infra-nodal system or if the heart rate is less than 50 beats/min with unstable vital signs.

What happens to heart in hyperkalemia? ›

Hyperkalemia occurs when potassium levels in your blood get too high. Potassium is an essential nutrient found in foods. This nutrient helps your nerves and muscles function. But too much potassium in your blood can damage your heart and cause a heart attack.

How is hyperkalemia treated in nursing? ›

Insulin and glucose, or insulin alone in hyperglycemic patients, will drive the potassium back into the cells, effectively lowering serum potassium. A common regimen is ten units of regular insulin given with 50 ml of a 50% dextrose solution (D50).

What medication is used to lower potassium? ›

Sodium polystyrene sulfonate (e.g.Kayexalate) - This medication works to lower blood potassium levels by binding with the potassium in your stomach or gut. You may take this medication by mouth, or by enema.

Does dextrose lower potassium? ›

Patients who received 50 g of dextrose had a median serum potassium reduction in 1.1 mEq/ml at 60 min following administration compared with 1 mEq/ml in patients who received 25 g of dextrose (p = 0.76).

Can you use subcutaneous insulin for hyperkalemia? ›

Treatment of hyperkalemia can include off-label use of both salbutamol and insulin. 1,2 The patient received the salbutamol by nebulizer, the D50W intravenously (based on instructions the nurse obtained from the pharmacist), and the regular insulin by subcutaneous injection.

Does hyperkalemia require hospitalization? ›

Severe hyperkalemia is a medical emergency and can lead to significant morbidity and mortality; it therefore requires hospitalization, ECG monitoring, and immediate treatment [16].

How is outpatient hyperkalemia treated? ›

Patients with hyperkalemia and characteristic ECG changes should be given intravenous calcium gluconate. Acutely lower potassium by giving intravenous insulin with glucose, a beta2 agonist by nebulizer, or both. Total body potassium should usually be lowered with sodium polystyrene sulfonate (Kayexalate).

Why is calcium given for hyperkalemia? ›

Calcium chloride

Calcium prevents the deleterious cardiac effects of severe hyperkalemia that may occur before the serum potassium level is corrected. Because of its irritating effects when administered parenterally, calcium chloride is generally considered a second choice, after calcium gluconate.

Why do you give sodium bicarbonate for hyperkalemia? ›

Patients having hyperkalemia often are given bicarbonate to raise blood pH and shift extracellular potassium into cells.

Why do we give calcium gluconate for hyperkalemia? ›

Calcium (either gluconate or chloride): Reduces the risk of ventricular fibrillation caused by hyperkalemia. Insulin administered with glucose: Facilitates the uptake of glucose into the cell, which results in an intracellular shift of potassium.

Severe hyperkalemia is a medical emergency and can lead to significant morbidity and mortality; it therefore requires hospitalization, ECG monitoring, and immediate treatment [16].

How do hospitals lower potassium levels? ›

Emergency treatment may include: Calcium given into your veins (IV) to treat the muscle and heart effects of high potassium levels. Glucose and insulin given into your veins (IV) to help lower potassium levels long enough to correct the cause.

How does dehydration cause hyperkalemia? ›

The body becomes dehydrated when it loses more fluids than it consumes. When the body doesn't have enough fluids, it can't process potassium properly, and potassium builds up in the blood, which can lead to hyperkalemia.

Why is insulin given for hyperkalemia? ›

IV regular insulin is often used during acute hyperkalemia management due to its quick onset of action and moderate duration of redistribution effect (off-label use) (1 ,2). Insulin 10 units is estimated to lower serum potassium by 0.6–1.2 mMol/L within 15 minutes of administration with effects lasting 4–6 hours (13).
