The use of oral prednisolone (2 mg/kg) to treat children admitted to h
ospital with acute asthma was assessed in a placebo controlled study.
Children were further randomised to receive either 0.15 mg/kg salbutam
ol every 30 minutes for the first three hours of admission, or 5 mg sa
lbutamol every one to four hours as needed. Treatment was double blind
and the assessor was unaware of the nebuliser regimen given. Children
were examined before and after treatment with salbutamol on arrival a
nd reassessed four hours after admission. Seventy children completed t
he study. Seventeen (46%) of 37 children receiving prednisolone and si
x (9%) of 33 receiving placebo were fit for discharge after four hours
of treatment. There was no significant difference between the two neb
uliser regimens. Clinical parameters indicative of asthma severity wer
e improved in all groups. Between group comparisons at reassessment sh
owed higher peak flows in those receiving prednisolone and nebulisers
every 30 minutes but differences were not significant for other parame
ters. Objective parameters indicating steroid efficacy over placebo we
re minimal. Despite this, those receiving prednisolone were more readi
ly identifiable as being fit for discharge within four hours of treatm
ent.
