Use of intravenous fluids in Hong Kong children hospitalised for diarrhoea and relationship to severity and aetiology

Abstract

This study assessed the clinical management and impact of diarrhoea aetiology (rotavirus positive/negative) and rotavirus genotype on diarrhoeal disease severity. Of 7391 diarrhoea admissions less than 5 years of age over a 2-year period, 80% of patients were tested for rotavirus, 87% were cultured for bacterial pathogens and 78% were assessed for both. Diarrhoeal severity scores were greatest in those children with mixed rotavirus and bacterial infections. Between 1.3 and 8.4% of infants were considered dehydrated yet intravenous fluids were used for 48% of infants (69% rotavirus positive, 72% mixed infection). These findings support the promotion of oral rehydration therapy over intravenous fluids.
