Percutaneous dilatational tracheostomy (PDT) has greatly replaced conventional surgery in modern intensive care units (ICU). However, complication still occurs with PDT. The authors hypothesize that retrograde puncturing of the trachea could notably reduce complications such as posterior wall or esophageal perforation, false track, puncturing endotracheal tube, and bronchoscope. Difficult anatomy is another consideration that can be sorted out with this technique.

Experimental Design

The authors developed a new wire (provisional patent applied) to puncture the trachea from the inside. The wire was tested on cadavers and on homemade constructed tracheal models from sheep trachea.

Main Outcome and Measures

This technique was successful on both human cadavers and homemade tracheal models. The technique could be promising for procedure ease and to minimize complications.
