Red Flags & When to Go In Person for Dehydration Signs (Child) - Triage

Audience: pediatric

Dehydration in children happens when they lose more fluids than they take in. It can be caused by illnesses like diarrhea, vomiting, or fever. Mild dehydration may be managed at home or through telemedicine, but recognizing serious signs is important. Watch for symptoms like dry mouth, decreased urine, or unusual sleepiness. Telemedicine can help assess symptoms, guide fluid intake, and monitor progress. However, some signs require urgent in-person care to prevent complications. This guide helps parents and caregivers know when to seek immediate medical attention and when telemedicine visits may be suitable for managing dehydration signs in children.

Red flags — go in person / ER

• No urine output for 8 hours or more – seek immediate medical care.
• Extreme sleepiness or difficulty waking the child – go to emergency services.
• Persistent vomiting or diarrhea causing inability to keep fluids down – urgent in-person evaluation needed.

What telemedicine can do

• Assessing mild dehydration symptoms.
• Providing guidance on fluid intake and home care.
• Monitoring symptom progression remotely.
• Answering caregiver questions about dehydration signs.

What telemedicine cannot do

• Performing physical exams or diagnostic tests.
• Treating severe dehydration requiring intravenous fluids.
• Managing complications like shock or altered consciousness.

FAQs

Can I treat my child’s dehydration at home?

Mild dehydration can often be managed at home by giving fluids like oral rehydration solutions, breast milk, or water. However, if your child shows any red flags or does not improve, seek medical care.

When should I use telemedicine for my child’s dehydration?

Telemedicine is helpful for assessing mild symptoms, getting advice on fluid intake, and deciding if in-person care is needed. It is not suitable for severe symptoms or emergencies.

What fluids are best for a dehydrated child?

Oral rehydration solutions (ORS) are recommended because they contain the right balance of salts and sugars. If ORS is not available, small sips of water or breast milk can be given. Avoid sugary drinks or sodas.

How can I tell if my child is severely dehydrated?

Severe dehydration signs include no urine for many hours, very dry mouth, sunken eyes or fontanelle, extreme sleepiness, rapid breathing, or cold skin. These require urgent medical care.

Is vomiting a reason to go to the hospital?

If vomiting prevents your child from keeping any fluids down, or is persistent, it is important to seek in-person care to prevent worsening dehydration.
