How often do children vomit after leaving the emergency department for acute gastroenteritis?
Acute gastroenteritis often causes vomiting in children. Research shows that roughly one-third of these children experience ongoing vomiting after they leave the emergency department. This continued vomiting can make it hard for kids to keep fluids down and may cause more worry for parents.
What the research says
A large study of over 1,000 children found that only about one-third of those with significant vomiting at the emergency department had ongoing vomiting after they went home. The main goal of the study was to see which children were likely to have three or more vomiting episodes within 24 hours of leaving the hospital 1.
Another study looked at how often specific germs cause illness in children with acute gastroenteritis. It found that many cases were caused by viruses like Norovirus and Rotavirus, which are common causes of vomiting and diarrhea in kids 2.
Doctors and pediatricians agree that vomiting is a major source of stress for families. They also note that giving certain medicines to stop vomiting at home can help some children who cannot keep fluids down. However, these medicines must be used carefully and only when needed 3.
What to ask your doctor
- How likely is my child to keep vomiting after we leave the emergency department?
- What signs should I watch for that mean my child needs to come back to the hospital?
- Is there a medicine that can help stop vomiting at home if my child cannot keep fluids down?
- How can I tell if my child is staying hydrated enough when they are vomiting?
