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

Abstract Purpose The saline-filled endotracheal tube (ETT) cuff can be easily identified under cervical ultrasound and can serve as an ideal puncture target during percutaneous dilatational tracheostomy (PDT). The authors present their initial experience with this novel technique. Materials and methods The records of 38 consecutive critically ill patients who underwent saline-filled cuff puncture PDT between October 2016 and December 2017 were retrospectively reviewed. The saline-filled ETT cuff was easily identified using ultrasound. Ultrasound-guided puncture into the cuff, followed by an inward-push of the ETT through the tube exchanger, facilitated accurate passage of the guidewire through the needle tip into the tracheal lumen. Results Of 38 consecutive procedures, 37 (97.4%) were performed successfully, with only one converted to surgical tracheostomy due to guidewire displacement. The median procedure time was 8 min. There were no complications, such as accidental extubation, major bleeding, or posterior tracheal wall laceration or pneumothorax, and no procedure-related mortalities. Conclusions 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.
