Hyponatremic dehydration: an analysis of 78 cases

Area of Science:

• Pediatrics
• Clinical Medicine
• Biochemistry

Background:

• Hyponatremic dehydration (HD) is a common condition in children, particularly in regions with high malnutrition rates.
• Convulsions are a serious complication of HD, and their frequency and associated factors require further investigation.

Purpose of the Study:

• To determine the frequency of convulsions in children with hyponatremic dehydration.
• To investigate the relationship between hyponatremia severity, malnutrition, and diarrhea type in pediatric patients.

Main Methods:

• Retrospective analysis of clinical and laboratory findings in 78 children with diarrhea and HD.
• Assessment of nutritional status using the Gomez classification and serum sodium (SNa) levels.
• Statistical analysis to determine correlations between variables.

Main Results:

• The overall frequency of convulsions in children with HD was 15.3% (12/78).
• Convulsions showed a tendency to increase with more severe hyponatremia (p < 0.05).
• No significant difference was found in convulsion frequency based on diarrhea type (acute, persistent, chronic) or between SNa levels and malnutrition severity.

Conclusions:

• Convulsions are a notable complication of hyponatremic dehydration in children.
• While malnutrition and diarrhea type did not significantly influence convulsion occurrence, severe hyponatremia emerged as a critical risk factor.
• Further research is warranted to elucidate the complex interplay between electrolyte imbalances, nutritional status, and neurological complications in pediatric dehydration.
