Oral rehydration solution in the year 2000: pathophysiology, efficacy and effectiveness.
The use of oral rehydration solution (ORS) with early refeeding forms the basis of therapy for dehydration secondary to diarrhoea ORS has produced such positive results in dehydrated patients that no further scientific demonstration is needed to confirm its efficacy. This review presents several issues that remain unsettled or controversial. They include the following. 1. The mechanism of water handling by the intestine is discussed; this is more complex than initially thought, at the epithelial, cellular and molecular level. 2. The composition of ORS which has been successfully adapted for the most frequent conditions, except for severely malnourished children, is described. 3. In contrast to the strong scientific basis and obvious efficacy in rehydration of ORS, its consequences for growth, nutrition and mortality are difficult to demonstrate, unless adequate long-term nutritional support is also provided in addition to ORS. 4. Finally, discrepancies between the recommendations and the practice of oral rehydration therapy are now well documented. Analysis of the causes of these discrepancies may participate in improving public health campaigns.
