Abstract
OBJECTIVE: To compare the safety and efficacy of a hyposmolar oral rehydration solution (H-ORS) (245 mmol/liter) with the World Health Organization oral rehydration solution (WHO ORS) in cholera and acute non-cholera diarrhea. DESIGN: Controlled clinical trial. SETTING:Diarrhea training and treatment unit. METHODS:Thirty-five culture proven cholera and 135 acute non-cholera diarrheal patients randomly received H-ORS or WHO-ORS. Intake and output were measured every 4 hours. RESULTS: Analysis of the total cases revealed rehydration phase (p=0.048, 95% CI 0.64-0.99) and overall (p=0.046, 95% CI 0.70-0.99) frequency of stools to be significantly less in the H-ORS group. In the severely malnourished, the rehydration phase (p=0.032, 95% CI 0.55-97), maintenance phase (p=0.035, 95% CI 0.51-0.97) and overall (p=0.011; 0.95% CI 0.55-0.93) stool frequency were significantly decreased in the H-ORS group. The amount of ORS consumed in the maintenance phase of the cholera cases was significantly (p=0.04, 95% CI 0.44-0.98) less in the H-ORS group. All other parameters, despite showing a decreasing trend, were statistically comparable in the cholera, non-cholera and total cases. The amount of intravenous fluid needed was significantly more in the noncholera and total cases on H-ORS. In the non-breastfed cases, under two years of age, the total duration of diarrhea was significantly decreased (p=0.03; 95% CI 11.07-11.45) but the need for intravenous fluids significantly increased (p=0.02; 95% CI 109.8-112.1) in the H-ORS group. The proportion of children vomiting, the weight gain, urine passed in 24 hours, serum sodium, caloric intake and failure rate were comparable. CONCLUSIONS: H-ORS is as safe and effective as the WHO-ORS and may have some additional benefits in malnourished children.
