Amount of Droplet Formed During Percutaneous Dilatational Tracheostomy

The patient is intubated with Tritube® after the removal of the conventional endotracheal tube (ETT) and Tritube® was advanced until proximal to the carina. Before starting the PDT, measurements with ATP bioluminescence-based method (3M Clean-trace®) were made by taking sample from a sterile PVC surface (10 cm2) which is held 50 cm over the operation site. After PDT with Griggs method (Portex), the measurements were repeated by taking sample from surface.
