Ultrasound-guided percutaneous dilatational tracheostomy using a saline-filled endotracheal tube cuff as an ultrasonographic puncture target: A feasibility study

PDT performed using a saline-filled cuff as the ultrasound-guided puncture target and an endotracheal tube exchanger is feasible, and appeared to be easier to perform than standard PDT. Larger studies are required to confirm the safety and benefits of this technique.
