Alternative methods and protection used in patients intubated for COVID-19-realyed respiratory distress. Left: Tracheostomy by hybrid technique (Tanaka et al. [32]) using a percutaneous kit under a protective suit (vertical transparent field). Tracheal approach (before opening) performed surgically, then Seldinger technique with guide-wire to dilate the trachea and introduce the cannula. Right: Surgical tracheostomy with protection interface (microscope cover) to minimise aerosolisation during tracheal opening.
