Sedation in Bronchoscopy: A Review.

Bronchoscopy has long been used as a diagnostic and therapeutic tool in medicine, with a wide range of appropriate sedative options. Flexible bronchoscopy is generally performed with sedation, and the choice of sedative is generally left to the practice pattern of the performing bronchoscopist. The concept of sedation is complex, with varying degrees of consciousness. A literature search was conducted on MEDLINE from 1969 to 2016, and appropriate data were reviewed. Randomized, controlled trials and prospective cohort studies were considered of highest impact. This article is a comprehensive review of existing data regarding sedation during bronchoscopy.
