Dyspnea

As with pain, dyspnea can have many causes. When anemia, bronchospasm, and heart failure have been excluded or treated, the focus should be on symptom control. Oxygen has been shown to be helpful for controlling dyspnea in patients with hypoxia, but may be less convenient and more expensive than opioids. When the dose of opioid is titrated carefully to control the pain and is administered on a regular schedule, with additional doses available for breakthrough dyspnea, the patient can obtain excellent relief without significant respiratory depression (Bruera et al., 1990).

Evidence from 13 studies shows a valuable effect of morphine for dyspnea in advanced lung disease and terminal cancer. However, using nebulized versus oral opioids showed no additional benefit. Good-quality evidence shows that long-acting beta agonists are beneficial in the treatment of dyspnea in chronic obstructive pulmonary disease (Qaseem et al., 2008).

It may also be helpful to provide cool, moving air (open window, fan) and keep an unobstructed line of sight between

1. Has an appropriate starting dose been determined?

2. Is a co-analgesic needed?

3. Is an antiemetic needed?

4. Has a laxative been prescribed?

5. Is the drug regimen written out in sufficient detail?

6. Has the patient been warned about possible side effects that might occur initially?

7. Do the patient and family know what to do if the pain remains uncontrolled?

8. Have arrangements been made for follow-up after 1, 3, and 7 days— either by the physician or by a trained hospice nurse?

9. Does the patient know what to do if he or she needs help or advice before the next follow-up visit?

10. Is the patient confident that the pain will improve considerably, probably within a few days, certainly within 1 or 2 weeks?

Because dyspnea can be controlled well without antibiotics, the physician must decide whether the antibiotics will improve the quality of life or just prolong the dying.
