Home-administered oral therapy for diarrhoea: a laboratory study of safety and efficacy

Serum electrolytes were measured for persons treated for diarrhoea at home with prepackaged or locally available sugar and salt oral rehydration therapy (ORT) solutions and for persons with diarrhoea who received no ORT but were treated according to local customs. No detrimental effect was found for persons treated with ORT at home; no significant difference was found in the frequency at which members of the groups had hypernatraemia. The rates of hyponatraemia and hypokalaemia were significantly lower for persons who took estimated appropriate volumes of ORT than for those who took less than appropriate volumes or for persons treated according to local customs without ORT. These laboratory results indicate that ORT administered in rural homes in Bangladesh was safe and effective under the conditions of our study.
