Clinical Evidence has a chapter on gastroenteritis in children. It considers oral rehydration solutions as being ‘beneficial’ (as effective as iv fluids). It also considers the following ‘likely to be beneficial:

  • Lactose-free feeds (reduces duration of diarrhoea)
  • Loperamide (reduces duration of diarrhoea, but adverse effects unclear)
  • Nasogastric rehydration (as effective as iv fluids)

Finally it reports clear fluids (other than oral rehydration solutions) as having ‘unknown effectiveness’.
