The vomiting CPG is a new CPG focusing on assessment and differential diagnoses and forms part of suite of hydration CPGs covering IV fluids, dehydration, vomiting and gastroenteritis.

The Key points for the CPG are

1. Bilious (dark green) vomiting is due to a gastrointestinal obstruction until proven otherwise, and requires urgent surgical referral
2. In a vomiting child without diarrhoea, consider causes other than gastroenteritis
3. Intracranial causes eg non-accidental injury (NAI), should always be considered
4. Ondansetron can be used for symptomatic relief, however cessation of vomiting does not exclude a serious cause
