Study summary

Considering the physiological changes in fluid and electrolyte balance and providing proper support are one of the important aspects of neonatal intensive care. Maintenance intravenous fluids are designed to maintain homeostasis when a patient is unable to uptake required water, electrolytes, and energy. Hypotonic fluids are still the most commonly prescribed IV fluids for pediatric hospitalized patients. However, previous studies, including children older than one month of age revealed that traditionally used hypotonic fluids may lead to hyponatremia.

Because of the absence of evidence-based data, there is currently no clear consensus on the optimal composition of maintenance intravenous fluid therapy in newborns, leading to wide practice variation.

The National Clinical Guideline Center (NICE) 2015 recommends the use of isotonic fluids in term newborn infants and some newborn centers has begun to use isotonic fluids since guidelines recommendations. Since the publication of the NICE guideline, no studies have addressed this topic.

In this prospective, observational , multicentric study, conventional hypotonic fluids containing sodium chloride (NaCl) \< 130 mmol/L compared with isotonic fluids (containing NaCl between 131-154 mmol/L) in terms of the risk of hyponatremia, hypernatremia, plasma sodium (pNa) level change, treatment morbidities, hospitalization duration and mortality.

Ran from Dec 2020 to primary completion in Dec 2022, 24 months.

Of 19 observational studies under Dehydration, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 30. This study's 24 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 27, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
