Tip 55b: fluid losses in preterm babies

Babies <1.5kg commonly require:

• high infusion rates (80-100ml/kg/day) of 10% dextrose on day 1
• diligent review of their fluid balance and clinical picture with reduction in fluids if required (e.g. hyponatraemia)
• delayed sodium supplementation until a significant diuresis has occurred (usually after day 1-2).
