Core tip: Many patients with chronic obstructive pulmonary disease (COPD) have to undergo upper gastrointestinal (GI) endoscopy because of digestive symptoms. A sedation method specially designed for elderly patients with COPD is urgently needed for use in clinical practice. In this study, we designed a new stepwise sedation method. Eighty-six elderly patients with COPD and 82 elderly patients without COPD scheduled for upper GI endoscopy were randomly assigned stepwise sedation or continuous sedation. The results indicate that the stepwise sedation method is effective and safer than the continuous sedation method for elderly patients with mild/moderate COPD during upper GI endoscopy.
