Abstract
BACKGROUND: The evidence to support the use of nebulized morphine to improve dyspnoea and exercise limitation in terminally ill patients with chronic lung disease is conflicting. OBJECTIVES: To assess the effectiveness of nebulized morphine in reducing dyspnoea in patients with end-stage interstitial lung disease SEARCH STRATEGY: RCTs and good quality CCTs were identified by searching Medline, Embase, Cinahl as well as the Cochrane controlled clinical trial register. The following search terms were used: (inhaled OR nebulised)/AND/morphine AND/Idiopathic pulmonary fibrosis/or/pulmonary fibrosis/or/idiopathic interstitial pneumonia/or/nonspecific interstitial pneumonia/or/non-specific interstitial pneumonia/or/usual interstitial pneumonia/or/desquamative interstitial pneumonia/or/cryptogenic fibrosing alveolitis/or/interstitial pneumonia/or/idiopathic interstitial lung disease/or/chronic interstitial pneumonia SELECTION CRITERIA: Any RCT and adequate quality CCT in adult patients with ILD that compared nebulized morphine with a control group. DATA COLLECTION AND ANALYSIS: Only one small RCT was identified. MAIN RESULTS: Compared to placebo (normal saline), administration of low-dose nebulized morphine (2.5 and 5.0 mg) to six patients with ILD did not improve maximal exercise performance, and did not reduce dyspnoea during exercise. REVIEWER'S CONCLUSIONS: The hypothesis that nebulized morphine may reduce dyspnoea in patients with interstitial lung disease has not been confirmed in the single small RCT identified.
