Paediatrics: how to manage viral gastroenteritis

Area of Science:

• Pediatrics
• Infectious Diseases
• Gastroenterology

Background:

• Viral gastroenteritis is a common cause of diarrheal illness in children presenting to primary care and emergency departments.
• This review provides an updated overview of the evaluation and management of viral gastroenteritis in pediatric patients.

Purpose of the Study:

• To review the current approaches to diagnosing and managing viral gastroenteritis in children.
• To highlight effective rehydration strategies and preventive measures.

Main Methods:

• A comprehensive literature search was conducted using PubMed with the keyword 'viral gastroenteritis'.
• The search included various study types (clinical trials, reviews, etc.) focusing on the pediatric population and English-language publications.

Main Results:

• Acute viral gastroenteritis is typically self-limiting but can cause dehydration and electrolyte imbalances.
• Oral rehydration therapy (ORT) is as effective as intravenous (IV) fluid therapy for mild to moderate dehydration in children.
• Ondansetron can improve ORT success rates, potentially reducing the need for IV therapy and hospitalization.

Conclusions:

• Physicians should counsel caregivers on hygiene practices and rotavirus vaccination to prevent transmission and illness.
• New norovirus vaccines are in development, offering hope for further reductions in viral gastroenteritis incidence.
