Why would a newborn have high potassium?
Extremely low birth weight premature infants are particularly prone to hyperkalemia primarily due to immature renal function. Even otherwise full-term infants may have transient hyperkalemia and hyponatremia due to decreased responsiveness to aldosterone (pseudohypoaldosteronism I).
How do you treat high potassium in newborns?
Treatment
- 10% Calcium Gluconate. Dose:
- Stop IV K⁺ Remove K⁺from IV (i.e.: replace TPN with 10% glucose with Na+)
- IV Glucose and Insulin. Dose:
- Salbutamol. Dose:
- Sodium bicarbonate. Correction of an existing metabolic acidosis can be considered.
- Resonium.
- Exchange transfusion or peritoneal dialysis.
Can a baby have too much potassium?
Can your child get too much potassium? Yes, although it’s highly unlikely. The Institute of Medicine has not determined an upper intake level for potassium, which would be the maximum amount considered safe. It’s important for the body to maintain a good potassium balance.
What does high potassium mean in a child?
High levels of potassium ( hyperkalemia ) may be due to: Addison disease (rare) Blood transfusion. Certain medicines including angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and the potassium-sparing diuretics spironolactone, amiloride and triamterene.
How do you treat high potassium levels?
Treatment
- 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.
- Kidney dialysis if your kidney function is poor.
How can I lower potassium in my baby?
An intravenous injection of soluble insulin (5-10 units) with 50 ml glucose 50% given over 5-15 minutes reduces serum-potassium concentration. This should be repeated if necessary or a continuous infusion should be started.
What can cause elevated potassium levels?
The leading causes of hyperkalemia are chronic kidney disease, uncontrolled diabetes, dehydration, an injury causing severe bleeding, consuming excessive dietary potassium, and some medications.
What is normal potassium level in a baby?
| Age | Range (mEq/L or mmol/L) |
|---|---|
| Premature infant | 4 to 6.5 |
| Newborn | 3.7 to 5.9 |
| Infant | 4.1 to 5.3 |
| Child >1 year old | 3.5 to 5 |
What is a normal potassium level for an infant?
The serum potassium level is 6.5 mEq/L in an extremely low birthweight infant. Normal potassium levels are generally between 3.5 and 5.5 mEq/L. Definitions can vary by weight, but most define hyperkalemia as >6 mEq/L in newborns. Hyperkalemia is common in extremely low birthweight infants.
How do hospitals treat high potassium?
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.
- Kidney dialysis if your kidney function is poor.
When should I be concerned about high potassium levels?
If hyperkalemia comes on suddenly and you have very high levels of potassium, you may feel heart palpitations, shortness of breath, chest pain, nausea, or vomiting. Sudden or severe hyperkalemia is a life-threatening condition. It requires immediate medical care.
