PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Vomiting is a coordinated motor response of the gastrointestinal tract, abdominal muscles, and thoracic muscles that results in the forceful expulsion of stomach contents. Vomiting must be differentiated from regurgitation, which is the effortless expulsion of gastric contents through the mouth (discussed in Chapter 394).1 Vomiting is a common presenting symptom in acute and chronic disorders of both gastrointestinal and nongastrointestinal origin. Evaluation and management requires consideration of a broad differential diagnosis, recognition of alarm symptoms requiring immediate intervention, treatment aimed at the symptom and/or cause, and prevention of potential complications.
