How do you calculate electrolyte replacement?
How do you calculate electrolyte replacement?
300 mL × 0.8 = 240 mL of insensible losses per 24 hours, or a rate of 10 mL/hour. Prescription for daily electrolytes: Sodium: 2 to 3 mEq/100 mL of fluid. Potassium: 2 mEq/100 mL of fluid….
Determined by Serum Sodium Concentration (mEq/L) | |
---|---|
Isotonic | 130-150 |
Hypertonic/Hypernatremic | >150 |
How do you calculate pediatric fluid replacement?
- For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg.
- For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10.
- For children >20 kg the daily fluid requirement is 1500 mL + 20 mL/kg for every kg over 20, up to a maximum of 2400 mL daily.
What is fluid and electrolyte replacement?
Electrolyte replacement in intravenous fluids generally includes sodium, potassium, and chloride. Chloride needs, which are 5 mEq/kg/day,11 are usually met by administering sodium and potassium as sodium chloride and potassium chloride salts.
How is pediatric potassium deficit calculated?
Kdeficit (in mmol) = (Knormal lower limit − Kmeasured) × kg body weight × 0.4. In this child, the calculated deficit would be (3.5 − 1.9) × 23 × 0.4, or 14.72 mmol. However, this formula does not take into account the chronic loss that this child has had and the fact that 98% of potassium is intracellular.
When do you replace potassium IV?
Replacement. Potassium replacement is indicated if: serum potassium <3.0 mmol/L or. serum potassium <3.5 mmol/L with symptoms/signs/ECG changes.
How do you calculate fluid replacement?
Alternatively, daily maintenance (not including pathologic ongoing loss) fluid requirements may be roughly estimated as follows: Less than 10 kg = 100 mL/kg. 10-20 kg = 1000 + 50 mL/kg for each kg over 10 kg. Greater than 20 kg = 1500 + 20 mL/kg for each kg over 20 kg.
How do you calculate IV maintenance fluid for pediatrics?
Maintenance Fluid Rate is calculated based on weight.
- 4 mL / kg / hour for the first 10kg of body mass.
- 2 mL / kg / hour for the second 10kg of body mass (11kg – 20kg)
- 1 mL / kg / hour for any kilogram of body mass above 20kg (> 20kg)
What is a normal potassium level for a child?
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 |
When do you replace potassium?
3. Potassium replacement is recommended for individuals who are subject to nausea, vomiting, diarrhea, bulimia, or diuretic/laxative abuse. Potassium chloride has been shown to be the most effective means of replacing acute potassium loss.
