Acute asthma and antidiuretic hormone secretion.

Abstract
Plasma antidiuretic hormone concentrations were measured in a group of children with acute asthma and in a control group. Very high levels of antidiuretic hormone were found in the asthmatic group. There were no changes in other biochemical indices. If overproduction of antidiuretic hormone is sustained then fluid administration to children with severe acute asthma is potentially dangerous.
