[Dyspnea in patients in palliative situations - the invisible symptom].

Abstract

Introduction: Dyspnea is a common and distressing symptom in patients with advanced malignant and non-malignant diseases. It is a subjective experience that can only be described by the patients themselves and can be associated with a massive reduction in quality of life, including social isolation and wish to hasten death. Often there is an affective component such as anxiety or panic. Objective parameters do not necessarily correlate with the subjective experience. Health professionals often underestimate and inadequately treat the burden of dyspnea. The introduction of the concept of chronic breathlessness syndrome or acute-on-chronic-breathlessness aims to illustrate the nature of the condition and facilitate the identification and access to appropriate treatment. The management of dyspnea is complex, and for effective treatment, a combination of general, non-pharmacological, and pharmacological measures is usually advisable. Opioids should be offered to patients with incurable cancer and refractory dyspnea for symptom relief. They can be supplemented with benzodiazepines in cases of concomitant anxiety. The administration of oxygen is only indicated in cases of hypoxemia. Key measures include education, self-management skills acquisition and advance care planning for emergency situations.
