Abstract
In the 7 years from 1982 to 1988, 10,639 children with acute asthma were admitted to the Royal Children's Hospital, Melbourne. Of these, 262 children (2%) were treated in the Intensive Care Unit. Twenty-seven required mechanical ventilation on 34 occasions, being 0.3% of hospital asthma admissions. Five patients died, four due to brain death following respiratory arrest prior to intubation. The main complications were (i) barotrauma, which occurred in five patients on seven occasions (20%); (ii) a reversible myopathy which occurred in three patients treated with high dose corticosteroids and muscle relaxants. Follow-up of patients ventilated in intensive care revealed that all but one of the initial survivors was alive 1-5 years later, all patients required subsequent readmission to hospital for treatment of acute asthma and 78% had persistent rather than episodic asthma. Although uncommon, an episode of ventilation has a major impact on the family's understanding and future management of acute asthma.
