[Nutrition management of patients with acute exacerbation of chronic obstructive pulmonary disease hospitalized in Respiratory Intensive Care Unit].

Acute exacerbation of chronic obstructive pulmonary disease (COPD) is an important part of the course of COPD. Patients with life-threatening acute exacerbation need to be admitted to the respiratory intensive care unit (RICU) for treatment in time. Malnutrition is common in COPD patients, and nutritional risk also has a high prevalence in patients with COPD exacerbation, which is closely associated with the clinical outcome and mortality of these patients. Identifying patients with high nutritional risk and providing appropriate nutritional treatment will help to improve survival rate, shorten length of hospital stay and reduce complications. This review describes the potential mechanisms of malnutrition in patients with COPD, the nutritional risk assessment of patients with COPD exacerbation hospitalized in RICU, the selection of nutritional treatment methods and formulas, and the relevant problems of nutritional management of patients required noninvasive ventilation, hoping to provide information for the optimization of nutritional treatment strategy for acute exacerbation of COPD and the exploration of clinical research in the future.
