• Pediatric acute gastroenteritis has always been a major cause of ED visits and hospitalizations.
• Pediatric complaints of vomiting and diarrhea have been on the rise, whether it be secondary to the new Omicron-variant of COVID-19, or norovirus and rotavirus which traditionally account for nearly 60% of all cases.
• Zofran (Ondansteron) 4mg for children 4-11yo weighing greater than 40kg, and up to 8mg for those older.
• Zofran prescription at discharge was associated with reduced rate of return at 72-hours and was not associated with masking alternative diagnosis like appendicitis and intussusception.
• Oral rehydration therapy (ORT) consisting of a low osmolarity solution containing sugar and salts along with zinc has also been shown to optimize treatment and diminish return visits. ORT is available in commercial packets, pre-mixed solutions, or can be made at home with table salt and sugar.
• Bottom Line: Consider providing a prescription of Zofran along with recommendations for oral rehydration therapy consisting of a low osmolarity solution containing sugar and salts to prevent outpatient treatment failure and return visits.
