In phase I, a bolus of fluid is given in order to restore blood volume to ensure adequate perfusion of critical organs, such as the brain.

Monitoring serum electrolytes is necessary if the patient has electrolyte abnormalities, but when examining hydration, the most important indices to watch are the clinical parameters mentioned earlier. The Holliday-Segard nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows:.

Each of these examples demonstrates a situation where there is an ongoing loss which would not be met by administering only maintenance fluids. Hydration status can have an important impact on drug therapy, and should be considered when using medications with large volumes of distribution. Maintenance fluids are given to compensate for ongoing losses and are required for all patients.

Each of these methods, while providing a reasonable estimate of maintenance fluids, cannot account for the physiologic changes that occur in hospitalized children. Any renal dysfunction requires frequent electrolyte monitoring. This equation, also listed in Table 2arrives at similar volumes of fluid as the traditional Holliday-Segar equation. Holliday and Segar collated information from a number of studies, including their own, and concluded the following:.

Additional factors must be taken into consideration when determining insensible fluid losses. Please review our privacy policy. The subsequent symptoms of hyponatremia were mistaken for a zegar reaction from promethazine, and the child was treated with diphenhydramine. The Holliday-Segar equation remains the standard method for calculating maintenance fluid requirements.

Requirements for children are higher than those for adults for multiple reasons. Treatment of burns in children. On the second post-operative day, the patient was unarousable, and this was confused for a side effect of receiving hydromorphone. Water loss and therefore water requirement is a function of caloric expenditure.

The changes that take place as a child grows have a great effect on fluid requirements, making special attention to fluid therapy essential in pediatric pharmacotherapy. In this situation, the volume of distribution may temporarily be increased, and thus a standard dose may lead to subtherapeutic serum concentrations.

In both of these cases, symptoms of hyponatremia were explained as side effects of drugs.

By paying close attention to the fluid needs of pediatric patients and monitoring response to fluid therapy, the pediatric pharmacist can have a positive influence on the health of the child. Notify me of new comments via email. formhla

Some more words of caution: Data from Rusconi F, et al. Monitoring Parameters for Srgar Fluid Therapy. You are commenting using your Twitter account. The most commonly used technique to calculate maintenance fluids for children is the Holliday-Segar method Table 2. Hydration status can affect the dose needed to achieve therapeutic concentrations, and dehydrated patients may be at risk for toxicity if standard doses of drugs with high volumes of distribution are used.
