A new endotracheal tube designed to enable a single operator to perform percutaneous dilatational tracheostomy while maintaining the airway, providing continuous bronchoscopic guidance, and minimizing procedural complications: demonstration of feasibility on a mannequin and a cadaver.
: We designed a double-lumen endotracheal tube (the EZ [Easy] Tracheostomy [EZT]) to enable a single operator to safely perform percutaneous dilatational tracheostomy (PDT) at the bedside while providing continuous bronchoscopic guidance. The EZT design also aims to ensure uninterrupted mechanical ventilation during most of the PDT procedure via a secure airway. It aims to significantly minimize hypoxia, hypoventilation, auto-positive end-expiratory pressure, airway loss, posterior wall laceration, and damage to the endoscope related to the current methodology. ⋯ : It is feasible for a single operator to perform PDT with continuous bronchoscopic guidance when using the EZT on cadaver and mannequin models. Clinical studies are warranted to evaluate this new tool.

Randomized Study of 21-gauge Versus 22-gauge Endobronchial Ultrasound-guided Transbronchial Needle Aspiration Needles for Sampling Histology Specimens.
: Histologic specimens obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) often provide valuable information for diagnosis or management decisions; however, little has been reported about the sampling yield. Besides the conventional 22-gauge needle, a 21-gauge needle is now available for this procedure. The purpose of this study was to elucidate and compare the respective histologic specimen retrieval yields of EBUS-TBNA using 21-gauge and 22-gauge needles. ⋯ : Histologic specimens can be obtained with a high sampling yield using either of the needles. Our study found no difference in the sampling yield between the 2 needles.
