Chronic obstructive pulmonary disease (COPD) is a disease characterized by incomplete reversibility of airflow limitation, with gradual progression, primarily involving the lungs, but also causing damage to various other organs outside the lungs. Its pathogenesis is mainly related to the regulation of apoptosis and promotion of inflammatory response by radical oxygen species (ROS) during oxidative stress (OS)1, affecting gene transcription and exacerbating protease-antiprotease imbalance finally2. It often causes chronic coughing, coughing up sputum, shortness of breath or difficulty breathing, wheezing, and chest tightness. According to a WHO survey, COPD is the third leading cause of death globally, posing a serious threat to human health, and by 2060, the number of deaths from this disease will exceed 5.4 million annually3. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) refers to acute changes in respiratory distress, cough, and sputum in COPD patients at baseline levels. AECOPD patients often experience shortened sleep time and decreased sleep quality due to various factors such as serious respiratory symptoms, nocturnal hypoxia, accompanying psychological problems, medication use, and socio-economic conditions4. Therefore, sleep disorders, including obstructive sleep apnea (OSA), restless leg syndrome (RLS), and insomnia, have become common complications for AECOPD patients, especially in elderly severe patients.
The reasons for sleep disorders in AECOPD patients include increased airway resistance and reduced airflow at night and/or in the morning, which aggravate ventilation disorders and ultimately lead to frequent awakenings, shortened sleep time, and difficulty falling asleep5,6. Moreover, the large financial burden of AECOPD on families makes patients often accompanied by anxiety, depression, and other psychological problems4. More notably, sleep disorders can, in turn, increase the risk of pulmonary hypertension in AECOPD patients and are closely related to higher disease severity, more frequent exacerbation, higher utilization of emergency medical services, and higher mortality rates7. According to the latest research, the prevalence of OSA, RLS, and insomnia in AECOPD patients, respectively, reached 29.1%, 21.6%, and 29.5%. Patients with OSA may have a higher risk of hypertension and diabetes. Patients with RLS are related to higher Epworth sleepiness scale (ESS) score and a longer COPD duration(year). Furthermore, insomnia is more common in female patients8. Therefore, it is essential to carry out timely nursing interventions for AECOPD patients with sleep disorders.
At present, the clinical treatment of AECOPD patients mainly focuses on improving respiratory symptoms while ignoring sleep problems. In addition, benzodiazepines, melatonin, melatonin receptor agonists, and antipsychotics used by patients with severe sleep disorders have adverse reactions such as respiratory inhibition, drug dependence, cognitive impairment, dizziness, and somnolence; therefore, it is mostly used for acute sleep disorders, while it is limited in the application of chronic sleep disorders9. Other special intervention methods, including nocturnal oxygen therapy, cognitive behavioral therapy for insomnia, and pulmonary rehabilitation exercise, are not commonly used because of their high cost, unclear effect, and difficulty in clinical practice4. Therefore, there is an urgent need to find an effective, safe, and simple treatment for AECOPD patients with sleep disorders.
Traditional Chinese Medicine (TCM) has a long history and rich experience in the treatment of sleep disorders. Acupoint application (AA) and ear plaster therapy (EPT) are both traditional Chinese medicine techniques. A systematic review study also found that AA and EPT have significant curative effects in the treatment of primary insomnia10. In this study, we will elucidate in detail the process and efficacy of the two treatments for AECOPD, including the medical equipment used, acupoint selection, treatment procedure, nursing, treatment of related accidents, etc. By comparing the changes in the Pittsburgh sleep quality index (PSQI) before and after treatment to evaluate their clinical efficacy, we aimed to provide a new reference for the clinical treatment of this kind of disease.
