Although most cases of acute gastroenteritis require minimal medical intervention, dehydration and hypoglycemia may develop in cases of prolonged vomiting and diarrhea. The mainstay of treatment for patients with mild-to-moderate dehydration with acute gastroenteritis is oral rehydration solution. Antiemetics allow for improved tolerance of oral rehydration solution, and, when used appropriately, can decrease the need for intravenous fluids and hospitalization. This course reviews the common etiologies of acute gastroenteritis, discusses more severe conditions that should be considered in the differential diagnosis, and provides evidence-based recommendations for management of acute gastroenteritis in pediatric patients presenting to urgent care.
