Full criteria & treatment guidance
Key cautions & base contact
- SO-P-090 does not supply an ondansetron dose below age 4 or a routine pediatric IV regimen.
- Use oral medication only when the child can safely tolerate it.
Assess severity
- Assess hydration, perfusion, mental status, abdominal symptoms, duration, and ability to tolerate intake. Repeated vomiting can produce hypovolemia.
- Maintain the airway and suction when needed. Consider an underlying illness rather than treating the symptom alone.
Fluid resuscitation
- If dehydration or poor perfusion is present, establish IV/IO and give saline 20 mL/kg, maximum 250 mL per bolus, with base contact.
- A pediatric-capable base is preferred. May repeat twice for three total boluses; reassess circulation and respiratory status between boluses.
Antiemetic & glucose
- For ongoing nausea/vomiting in a child age 4 or older, give one 4 mg ondansetron ODT tablet to dissolve orally as tolerated. This is a fixed dose, not mg/kg.
- If altered or unresponsive, check glucose. Below 60 mg/dL, use oral glucose only with intact airway reflexes, D10 5 mL/kg IV (maximum 250 mL), or glucagon 0.5 mg IM if IV cannot be established. IO dextrose requires the listed additional criteria.
Reassessment & handoff
- Reassess vomiting, airway protection, hydration, mental status, glucose response, and treatment tolerance. Marked hyperglycemia with vomiting may indicate DKA; evaluate the full clinical picture instead of assuming gastroenteritis.
- Provide ALS transport to the nearest appropriate ERC and contact base as needed. Document age, weight, fluid totals, medication, and response.
UNDERSTAND THE CARE
Why age eligibility and weight-based care are different checks
The pediatric order contains both weight-based fluid treatment and a fixed, age-restricted antiemetic. A weight calculation cannot remove the medication’s age restriction or create an IV regimen. Establish the child’s age, weight, airway safety and severity before choosing the relevant instruction.
Applying the guidance
After treatment, assess more than vomiting frequency. Repeat mental status, perfusion, breathing and treatment tolerance, and check glucose when indicated by altered responsiveness. Persistent poor perfusion or marked hyperglycemia with vomiting should keep the underlying illness in view even when nausea improves.
Putting it together
Teaching example: a child younger than the stated ODT age has ongoing vomiting. Use the assessment and supportive-care pathway and seek appropriate direction rather than calculating a smaller adult or older-child dose.
