Palliative care and pain: new strategies for managing opioid bowel dysfunction.
Opioid analgesics are a cornerstone of pain therapy in the hospice and palliative care population. However, opioid-induced bowel dysfunction (OBD) is a commonly associated condition that frequently compromises the usefulness of these agents. Although its most common and debilitating symptom is constipation, the impact of OBD extends beyond constipation to encompass a myriad of gastrointestinal (GI) signs and symptoms, ranging from decreased gastric emptying and reflux to abdominal pain, cramping, bloating, nausea, and vomiting. ⋯ The net result of OBD is a seriously negative impact on quality of life (QOL). For these reasons, it is important that palliative care practitioners have an adequate understanding of normal GI function and the underlying mechanisms responsible for OBD, the burden of OBD in the context of appropriate and effective pain management, and the benefits provided by effective pharmacotherapy. Several real-world cases are discussed to illustrate the application of optimal symptom management and the use of strategies that minimize the effects of OBD and improve patient QOL.
