“The formula for the current WHO oral rehydration solution (also known as low-osmolar ORS or reduced-osmolarity ORS) is 2.6 grams (0.092 oz) salt (NaCl), 2.9 grams (0.10 oz) trisodium citrate dihydrate (C6H5Na3O7⋅2H2O), 1.5 grams (0.053 oz) potassium chloride (KCl), 13.5 grams (0.48 oz) anhydrous glucose (C6H12O6) per litre of fluid. This is 44 mmol salt, 10 mmol trisodium citrate dihydrate, 20 mmol potassium chloride, and 75 mmol anhydrous glucose per litre. This would have a total osmolarity of (44×2 + 10×4 + 20×2 + 75) = 243 mOsm/L.
A basic oral rehydration therapy solution can also be prepared when packets of oral rehydration salts are not available. It can be made using 6 level teaspoons (25.2 grams) of sugar and 0.5 teaspoon (2.9 grams) of salt in 1 litre of water. The molar ratio of sugar to salt should be 1:1 and the solution should not be hyperosmolar. The Rehydration Project states, “Making the mixture a little diluted (with more than 1 litre of clean water) is not harmful.”
WHO/UNICEF guidelines suggest ORT should begin at the first sign of diarrhea in order to prevent dehydration. Babies may be given ORS with a dropper or a syringe. Infants under two may be given a teaspoon of ORS fluid every one to two minutes. Older children and adults should take frequent sips from a cup, with a recommended intake of 200-400 ml of solution after every loose [bowel] movement. WHO recommends giving children under two a quarter- to a half-cup of fluid following each loose bowel movement and older children a half- to a full cup. If the person vomits, the caretaker should wait 5–10 minutes and then resume giving ORS.(Section 4.2) ORS may be given by aid workers or health care workers in refugee camps, health clinics and hospital settings. Mothers should remain with their children and be taught how to give ORS. This will help to prepare them to give ORT at home in the future. Breastfeeding should be continued throughout ORT.”
I strongly encourage your readers to do a little online research into how to treat dysentery, and how to mitigate the dangerous effects of dehydration, through the appropriate administration of oral rehydration solution.
