Epidemiological, Clinical and Biological Characteristics and Therapeutic Management of ICU Patients With Severe Acute Exacerbation of COPD. Evaluation of Prognosis and Factors Associated With Survival.
The objective of this prospective observational study is to describe the epidemiological, clinical and biological characteristics of admitted patients in ICU for severe acute exacerbation of COPD, to assess the different therapeutics used, to evaluate the prognosis of patients with short, medium and long term ( 1 year) and the various factors associated with survival in ICU
• Age ≥ 40 years old
• COPD documented or strongly suspected
‣ Chronic respiratory symptoms (dyspnoea, cough and/or sputum)
⁃ Exposure to a known risk factor for COPD (such as tobacco smoke)
⁃ If available, respiratory function tests showing non- or partially reversible obstructive syndrom (post-bronchodilator ratio FEV1/CV \< 0.7)
• Severe acute exacerbation, defined as a worsening of the patient's usual respiratory symptoms with signs of acute respiratory distress (polypnoea ≥ 30 cycles.min-1 or use of accessory respiratory muscles) and/or hypercapnic acidosis (with PaCO2 ≥ 45 mmHg and pH ≤ 7.35)
• Admission to an ICU, a step-up unit or a respiratory care unit
