Infantile diarrhea; tolerance to solutions of electrolytes by mouth

Area of Science:

• Pediatrics
• Gastroenterology

Background:

• Oral rehydration therapy is crucial for infants with diarrhea.
• Gastric distress is often associated with oral electrolyte solutions due to high osmolarity.
• Determining optimal osmolarity for infant tolerance is essential for effective treatment.

Purpose of the Study:

• To evaluate the tolerance of varying osmolarities of a commercial oral electrolyte solution in infants with diarrhea.
• To identify an osmolarity that minimizes gastric distress and refusal in pediatric patients.

Main Methods:

• A commercially prepared oral electrolyte solution was administered to 29 infants with acute diarrhea and dehydration.
• The solution was tested in two concentrations: undiluted (20x physiologic osmolarity) and diluted 1:3 with 5% glucose (6x physiologic osmolarity).
• Infant tolerance, including refusal and vomiting, was recorded for each concentration.

Main Results:

• Undiluted solution (20x) was well-tolerated, with only one of 29 infants refusing or vomiting.
• Diluted solution (6x) showed slightly lower tolerance, with one infant vomiting and two refusing.
• Hospital stay duration was not significantly affected by the oral electrolyte solution's use.

Conclusions:

• Infants with diarrhea demonstrate a high tolerance for oral electrolyte solutions, even at high osmolarities.
• Readily accepted oral solutions facilitate the discontinuation of parenteral electrolyte administration post-initial fluid replacement.
• Optimizing oral electrolyte solution osmolarity can improve patient compliance and potentially streamline care in pediatric diarrhea.
