Answer

Serum and urine chemistry, in particular sodium values, should be ascertained immediately and monitored at intervals throughout treatment. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) develops in approximately half of all cases of Hib meningitis. It may cause stupor or seizure and may contribute to the elevation of intracranial pressure.
