Oral rehydration therapy for low birth weight neonates suffering from diarrhea in the intensive care unit

Area of Science:

• Neonatal care
• Pediatric gastroenterology
• Clinical nutrition

Background:

• Diarrhea is a common issue in neonatal intensive care units.
• Low birth weight (LBW) neonates are particularly vulnerable to dehydration.
• Effective rehydration strategies are crucial for improving outcomes in LBW infants.

Purpose of the Study:

• To evaluate the safety and efficacy of oral rehydration therapy (ORT) using the World Health Organisation (WHO) formula in low birth weight (LBW) neonates with diarrhea.
• To assess the impact of ORT on electrolyte balance and fluid status in this vulnerable population.
• To compare ORT outcomes with traditional intravenous rehydration methods.

Main Methods:

• A cohort of 62 LBW neonates with diarrhea was observed.
• Dehydration severity was assessed using the Fortin-Parent score.
• ORT was administered via feeding bottle or nasogastric tube, with subsequent formula feeding (cow's milk-based or soy-based).
• Intravenous rehydration was reserved for severely hypovolemic cases.

Main Results:

• 92% of neonates experienced diarrhea lasting less than 1 day.
• ORT effectively corrected hyponatremia and hypernatremia.
• Only two neonates developed mild asymptomatic hypernatremia; none became edematous.
• The WHO ORT regimen was safely administered to all LBW neonates.

Conclusions:

• Oral rehydration therapy using the WHO solution is a safe and effective treatment for diarrhea in LBW neonates.
• ORT successfully corrects dehydration and electrolyte imbalances, leading to excellent outcomes.
• This approach avoids the need for invasive procedures, improving patient comfort and safety.
