Objective: To evaluate the efficacy and safety of nebulized morphine for the management of dyspnea in chronic pulmonary diseases.
Data Sources: MEDLINE (1966-May 2004), EMBASE (1980-May 2004), and International Pharmaceutical Abstracts (1970-May 2004) searches were performed. Key search terms included morphine, dyspnea, and inhalation.
Data Synthesis: Nine studies have evaluated the efficacy of nebulized morphine in relieving dyspnea. Three trials had positive results, but the rest failed to show improvement after treatment with doses ranging from 1 to 40 mg nebulized morphine. The small number of subjects, variety of disease states, and different outcome measures limit interpretation of the studies.
Conclusions: Results from several small studies do not support the use of nebulized morphine for treatment of dyspnea; however, several positive case reports have been published.

Challenges of acute pain management in older patients.
Age Ageing

Adequate management of acute pain in the older population is crucial. However, it is inherently complex because of multiple physiological changes that significantly impact both the pharmacokinetics and pharmacodynamics of medications. Current guidelines promote paracetamol as the first-line analgesic for acute pain in older adults, whereas opioids are advised cautiously for moderate to severe acute pain.

Objective: Our study aimed to investigate the analgesic efficacy of nebulized ketamine in managing acute moderate-to-severe musculoskeletal pain in older emergency department (ED) patients compared with intravenous (IV) morphine.
Methods: This was a non-inferiority, double-blind, randomized controlled trial conducted at a single medical centre. The patients aged 65 and older, who presented at the ED musculoskeletal pain within 7 days and had a pain score of 5 or more on an 11-point numeric rating scale (NRS), were included in the study.

The objective of this systematic review is to consolidate the existing evidence on opioid use, including administration, dosing, and efficacy, for the relief of dyspnea at end of life. The overarching goal is to optimize clinical management of dyspnea by identifying patterns in opioid use, improving opioid management of dyspnea, and to prioritize future research. Opioids are commonly used in the management of dyspnea at end of life, yet specific administration guidelines are limited.
