Letter: Heat prostration in children with cystic fibrosis.

We wish to report three cases of hyponatraemic dehydration in children with 
cystic fibrosis admitted to this hospital in late June and early 
July this year. These three children with cystic fibrosis clearly illustrate 
the danger of the present unusual climatic conditions. The necessity of 
salt supplementation in these environmental circumstances should be emphasised to all 
concerned and, above all, to parents. The danger of the administration 
of salt-free glucose solutions also should be borne in mind. In 
the past the case has been argued for a safe electrolyte 
solution that would be commercially available. In the absence of such 
a readily available form of electrolyte-glucose solution parents will need explicit 
instructions on how the salt supplement should be administered.
