What is oral fluid maintenance?
- Maintenance fluid is a water and electrolyte solution which aims to replace the excessive loss of water and electrolytes through skin and through urinary system.
- This therapy was given by Holliday and Segar.
- Maintenance fluids consist of water, glucose, potassium and sodium.
- This is especially given to those children who are NPO (Nothing by mouth).
- The rate at which maintenance fluid is given depends upon the patient’s size and weight.
- For children weighing >20kg, the daily maintenance fluid required is given by 1500 mL + 20 mL/kg for every kg over 20 (cannot exceed 2400 mL/day)
- For a child weighing 45 lb (20.5 kg), the daily fluid requirement is 1500+ (0.5* 20) = 1510 mL.
