Randomized Study With Midazolam for Sedation in Flexible Bronchoscopy

The Flexible Bronchoscopy (FB) is a diagnostic and therapeutic procedure which is not usually tolerated by the patient. This makes the examination more difficult and a repetition of the examination, if necessary, resulting in a lower diagnostic performance. Furthermore, there is nowadays little information with a highly obvious level about the relationship between sedation and the patient´s satisfaction with the FB. Midazolam is one of the most commonly used sedatives at the beginning for its rapid onset property and brief duration of action with sedatives, anxiolytics and amnesia properties. The principal aim of our study is to analyse if the use of a local anaesthetic with midazolam whilst performing an FB improves the quality of examination in terms of tolerance for the patient. It would also be of interest to know if there is an improvement in the acceptance of a second or further FB and if this improves the satisfaction of the Bronchoscopist as far as the examination performed is concerned.
