AbstractThe aim of this study was to compare the effect of three different intravenous (i.v.) fluid regimes on the incidence of hyponatraemia in hospitalized children ranging in age from 3 months to 12 years. Children who required the administration of i.v. maintenance fluid for at least 24 h following hospitalization were eligible for inclusion. The children were randomized to three i.v. fluid groups: Group A, 0.9% saline in 5% dextrose at the standard maintenance rate; Group B, 0.18% saline in 5% dextrose at the standard maintenance rate; Group C, 0.18% saline in 5% dextrose at two-thirds of the standard maintenance rate. The primary outcome measure was incidence of hyponatraemia (plasma sodium < 130 mEq/L). Of the 167 patients enrolled, 58, 56 and 53 patients were randomized to Group A, B and C, respectively. We observed that 14.3% (8/56) of the children administered 0.18% saline in 5% dextrose at the standard maintenance rate (Group B) developed hyponatraemia compared with 1.72% of the children in Group A and 3.8% of those in Group C. Based on these results, we conclude that the administration of 0.9% saline in 5% dextrose as i.v. maintenance fluid helps in reducing the incidence of hospital-acquired hyponatraemia among children.
