Disposition

Patients with life-threatening causes of vomiting should be admitted to the hospital, as should severely dehydrated patients with presumably self-limited causes of emesis. The patient in whom the diagnosis is unclear, but who the physician feels confident does not have a life-threatening cause of emesis, may be discharged safely, provided the patient tolerates fluids in the emergency department and that follow-up the next day, if vomiting continues, is ensured. A dehydrated patient who cannot tolerate oral intake should not be discharged.
