[Rapid intravenous rehydration in acute diarrhea]

With the use of oral rehydration, the need for the use of endovenous rehydration has decreased considerably. Albeit, the use is still necessary in severely dehydrated patients or when oral rehydration fails. Textbooks produced in developed countries recommend slow administration of fluids to correct dehydration in 12 to 24 hours. In developing countries, due to the great number of severely dehydrated patients, this approach is not useful. We developed, during the last 20 years, an approach to intravenous rehydration that permits rehydration of the severely ill patient in a much shorter time (2 to 3 hours) and permits an early refeeding. It can be used in all patients, even newborns or malnourished. No laboratory tests are necessary. Only a small number of simple and readily available solutions are used to prepare the electrolyte mixtures.
