What is the appropriate amount of oral rehydration solution (Pedialyte) for a 190-pound male with gastroenteritis?

From the Guidelines

For a 190-pound male with gastroenteritis, the recommended amount of oral rehydration solution (Pedialyte) is 2-4 L over 3-4 hours, as per the 2017 Infectious Diseases Society of America clinical practice guidelines 1. The guidelines suggest that adolescents and adults (≥30 kg) with mild to moderate dehydration should receive ORS, 2–4 L, and this recommendation is based on the patient's weight and severity of dehydration.

• The patient should start with small sips every 15 minutes and gradually increase intake as tolerated.
• In addition to Pedialyte, the patient should continue to drink water and clear broths.
• It is also recommended to avoid caffeine and alcohol, and eat small, bland meals (e.g., bananas, rice, toast) once able to keep fluids down.
• If symptoms worsen or the patient can't keep fluids down for 24 hours, they should seek medical attention, as severe dehydration may require intravenous fluids 1. The use of Pedialyte is supported by the guidelines, which state that low-osmolarity ORS can be given to all age groups, with any cause of diarrhea, and is safe in the presence of hypernatremia as well as hyponatremia (except when edema is present) 1.
