[An evidence based Iberic-Latin American guideline for acute gastroenteritis management in infants and prescholars].

Acute gastroenteritis (AG) morbidity and mortality rates in infants and prescholars continue to be high in developing countries. Authors want to develop an evidence-based document that supports decision making regarding AG therapy in infants and children younger than 5 y/o. A systematic review of the literature was performed (May, 2008). Evidence grading was established according to Oxford guidelines and Latin American experts submitted their opinions on the recommendations generated. Oral rehydration solutions are the threatment's keystone for children with AG, showing lesser complications due to therapy than IV fluids. AG is no contraindication of a normal diet. Racecadotril, zinc and smectite can contribute to AG treatment, as well as Lactobacillus GG and Saccharomycces boulardii. No other drugs are recommended. It is recommended to treat children presenting AG with oral rehydration solutions among racecadotril, zinc or smectite as well as some probiotics.
