Understand the importance of early feedings on the nutritional status of a child who commentary does has gastroenteritis. Fully understand that antidiarrheal agents are not indicated nor recommended in the an unapproved/ treatment of acute gastroenteritis in children. Recognize the role of vomiting in the clinical presentation of acute gastroenteritis. Introduction Acute gastroenteritis is an extremely common illness among infants and children world- wide. In developing countries, diarrhea is a common cause of mortality among children younger than age 5 years, with an estimated 2 million deaths each year. American children younger than 5 years have an av- erage of two episodes of gastroenteritis per year, leading to 2 million to 3 million ofce visits and 10% of all pediatric hospital admissions. Furthermore, approximately one third of all hospitalizations for diarrhea in children younger than 5 years are due to rotavirus, with an associated direct cost of $250 million annually. Stool patterns may vary among children; thus, it is important Abbreviations to note that diarrhea should represent a change from the norm. Vomiting followed by diarrhea may be the initial presentation in children, or vice versa. Recent medications and the childs Cryptosporidium immunization history also should be reviewed. The phys- Giardia lamblia ical examination should focus on identifying signs of de- Entamoeba histolytica Helminths hydration such as level of alertness, presence of sunken Strongyloides stercoralis eyes, dry mucous membranes, and skin turgor. Bacterial infections may result also divided patients into three groups: no signs of dehydra- in inltration of the mucosal lining of the small and large tion (<3%5%), some signs of dehydration (5%10%), and intestines, which in turn causes inammation. Furthermore, more obvious clinical signs of dehydration Assessment of Dehydration become apparent at 5% dehydration, and indications of Dehydration related to acute gastroenteritis is a major severe dehydration become evident when the uid loss reaches 9% to 10%.

These guidelines classied patients into three groups Laboratory Evaluation based on their estimated uid decit: mild dehydration Serum electrolytes are not indicated routinely in patients (3%5% uid decit), moderate dehydration (6%9% who have acute gastroenteritis. Authors of several studies uid decit), and severe dehydration (>10% uid decit have evaluated the utility of laboratory tests in assessing or shock).
