Atropine sublingual drops are appropriate for managing the "death rattle," which is the term used to describe the abnormal respiratory sounds that occur when a person is nearing death, often due to accumulation of secretions in the throat and airways. Atropine is an anticholinergic medication that reduces the production of secretions by blocking the action of acetylcholine on the secretory glands.
In end-of-life care, the goal is to provide comfort, and managing excessive secretions can alleviate distress for both the patient and their family. By using atropine, it helps dry up these secretions, thus minimizing the gurgling or rattling sounds that can be distressing.
Other options may have roles in palliative care, but they do not directly address the management of secretions like atropine does. For instance, lorazepam may help with anxiety, morphine can manage pain and discomfort, and ondansetron is primarily used for nausea. However, none of these directly target the excessive secretions responsible for the "death rattle."
