Specific Treatments
- A dehydrated child with oliguria/anuria should receive a fluid bolus of normal saline or lactated Ringer’s solution at 20 mL/kg to restore fluid volume.
- Depending on response, another bolus may be needed.
- Estimation of volume status is needed to begin and continue fluid therapy.
- Amount is assessed by history and physical exam that includes assessment of:
- Body weight
- Anterior fontanelle in infants
- Heart rate
- Mucous membranes
- Skin turgor
- Capillary refill
- Peripheral edema
- Blood pressure
- Children with oliguria and volume overload may:
- Benefit from furosemide
- Require fluid restriction
- Need blood pressure and acid-base monitoring
- Children with oliguria due to obstruction may require urinary catheterization.
- Relief of obstruction may be followed by postobstructive diuresis and may need fluid/electrolyte replacement.
