Tolerance and Safety of 5 Models of Sedation During Endobronchial Ultrasound.

Introduction: Sedation during endobronchial ultrasound (EBUS) is essential due to the long duration of this procedure. We evaluated different models of sedation and their complications.

Method: A multicenter, prospective, observational study of 307 patients undergoing EBUS was conducted.

Temporal patterns in severe hemoptysis requiring bronchial artery embolization.

Background: Although some authors have suggested that there is some seasonal periodicity in hemoptysis, temporal patterns of hemoptysis have been poorly investigated. The aim of this study is to describe the temporal pattern of severe hemoptysis which required bronchial artery embolization (BAE).

Methods: All consecutive patients with at least one episode of hemoptysis which required BAE during a 13-year period were included.
