Nebulised DNase post-therapeutic bronchoalveolar lavage in near fatal asthma exacerbation in an adult patient refractory to conventional treatment.

Mucus plugging plays a vital role in the pathophysiology of fatal and near fatal asthma as demonstrated in various postmortem studies. There is a paucity of published literature on how to manage mucus plugging in adult patients with refractory asthma exacerbation not responding to conventional therapies as compared with its paediatric cohort. We describe a dramatic improvement with the use of rhDNase, following bronchoalveolar lavage in an intubated adult female patient, with status asthmaticus refractory to conventional treatment.
