Nebulized morphine in the palliation of dyspnoea.

Seventeen terminally ill cancer patients with primary or secondary intra- thoracic malignancy complaining of breathlessness were treated with nebulized morphine in doses of 20 mg 4-hourly for 48 h. The effect on dyspnoea was evaluated using the Dyspnoea Assessment Questionnaire. Most patients felt less dyspnoeic after 24 h; the effect was maintained, but not improved upon, after 48 h.
