The Holliday-Segar method estimates the fluid a child needs to replace insensible losses (breathing, sweating) and urine output at rest. It was described by Holliday and Segar in 1957 and remains the standard starting point for paediatric maintenance fluid calculations in the UK and internationally. These figures represent maintenance requirements only — they do not account for deficit replacement, ongoing losses, or clinical conditions that alter fluid balance. Always refer to local paediatric fluid guidelines.
