A rough estimate of oral rehydration rate for older children and adults is ml of ORS every 5 minutes, until the patient stabilizes. Made up with clean water the ORS drink contains the main elements that are lost from the body during diarrhea. It is effective in treating dehydration resulting from all types of acute diarrhoeal diseases.
Many countries now have diarrhoeal disease control programmes, but ORT is still not nearly as widely used as it should be and more effective information dissemination and promotion of ORT is necessary. Diarrhoea is an intestinal disorder characterized by abnormal fluidity and frequency of fecal evacuations, generally the result of increased motility in the colon; may be an important symptom of such underlying disorders as dysenteric diseases, lactose intolerance, GI tumors, and inflammatory bowel disease.
Diarrhoea is the passage of watery stools. This means body fluids and salts can be quickly lost from the body. The child becomes dry dehydrated and this is very dangerous and may kill the child. Why is diarrhoea dangerous? When a person gets diarrhoea, the body begins to lose a lot of water and salts - both of which are necessary for life. If the water and salts are not replaced fast, the body starts to "dry up" or get dehydrated. Severe dehydration can cause death.
What is dehydration? Dehydration is the loss of water and body salts through diarrhoea. The human body needs water to maintain enough blood and other fluids to function properly. If your body loses substantially more fluids than you are drinking, you become dehydrated. You may lose fluids in a variety of ways:. Along with the fluids, your body also loses electrolytes, which are salts normally found in blood, other fluids, and cells. How does dehydration occur?

The above ingredients are dissolved in one litre of clean water. WHO has recently recommended a change in the complete formula, replacing 2. The new formula gives the packets a longer shelf life and is at least as effective in correcting acidosis and reducing stool volume.
Packets containing sodium bicarbonate are still safe and effective. How does ORT work? Acute diarrhea normally only lasts a few days. ORT does not stop the diarrhoea, but it replaces the lost fluids and essential salts thus preventing or treating dehydration and reducing the danger. The glucose contained in ORS solution enables the intestine to absorb the fluid and the salts more efficiently. How do I use an ORS package? Packets of oral rehydration salts are widely available.
