Does fluid restriction improve outcomes in infants with hypoxic ischemic encephalopathy? A pilot randomized...

Area of Science:

• Neonatal Medicine
• Pediatric Neurology
• Critical Care Medicine

Background:

• Hypoxic ischemic encephalopathy (HIE) is a serious condition in term neonates.
• Therapeutic hypothermia is a standard treatment for moderate to severe HIE.
• Fluid management is crucial in neonatal care, but optimal strategies for HIE are debated.

Purpose of the Study:

• To determine if restricting fluid intake in the first four days of life reduces mortality and major neurodevelopmental disability in term neonates with moderate to severe HIE.
• To assess the impact of fluid restriction on other morbidities, such as hypoglycemia.

Main Methods:

• A randomized controlled trial involving 80 term neonates with moderate to severe HIE.
• Participants were assigned to either normal fluid intake or restricted fluid intake (two-thirds of normal) for the first four days.
• The primary outcome was a composite of death or major neurodevelopmental disability at six months of age.

Main Results:

• The composite outcome of death or major neurodevelopmental disability occurred in 26% of the fluid-restricted group versus 8% in the normal fluid intake group (p=0.065).
• Hypoglycemia was observed in five infants in the fluid-restricted group, showing a trend toward statistical significance (p=0.055).

Conclusions:

• Restricted fluid intake in the initial four days of life did not significantly reduce the composite outcome of death or neurodevelopmental disability in neonates with HIE.
• The findings suggest that fluid restriction may be associated with an increased risk of hypoglycemia in this population.
