Outcome of patients with severe asthma in the intensive care unit

BACKGROUND: Because little has been reported about the outcome of severe asthma outside the US and western Europe, we performed a retrospective case analysis of patients treated in the medical intensive care unit (MICU) of a university hospital in Riyadh, Saudi Arabia, to determine the management, complications and outcome of severe asthma requiring ICU admission. METHODS: The records of patients with severe asthma admitted to the MICU between the periods of January 1996 to December 2003 were reviewed. Sixty-one episodes from 54 patients were studied, of which 27 (44%) were male. RESULTS: All patients were hypercapnic; 23 (38%) were ventilated. The Acute Physiological and Health Evaluation (APACHE) score II was significantly higher in the ventilated group (P < 0.0001). The pH was significantly lower and PaCO(2) was significantly higher in the ventilated group (P < 0.0001). All patients survived. Only 42% of patients our series received inhaled corticosteroids before admission. CONCLUSION: Our results suggest that severe asthma requiring ICU admission is now safely managed in ICUs. Our results are comparable to recently published data on the treatment of severe asthma in the ICU.
