Randomized Controlled Trial Comparative StudyA Comparison of the Required Bronchial Cuff Volume Obtained by 2 Cuff Inflation Methods, Capnogram Waveform-Guided Versus Pressure-Guided: A Prospective Randomized Controlled Study.
Double-lumen endobronchial tubes (DLTs) are used for one-lung ventilation (OLV) during thoracic surgery. Overinflation into the bronchial cuff causes damage to the tracheobronchial mucosa, whereas underinflation leads to an incomplete collapse of the nonventilated lung or incomplete ventilation of the ventilated lung. However, how to determine the appropriate bronchial cuff volume and pressure during OLV is unclear. The objective of this study is to compare the required bronchial cuff volume for lung separation obtained by 2 different cuff inflation methods under closed- and open-chest conditions. ⋯ The lowest cuff volume providing an air-tight bronchial seal was obtained by the capnogram waveform-guided bronchial cuff inflation method. Since the cuff volume required to achieve an air-tight seal decreases after opening the chest, readjustment of the bronchial cuff volume to prevent bronchial cuff damage to the tracheobronchial mucosa after opening the chest may be advisable.

Drape to prevent disease transmission during endotracheal intubation.
Endotracheal intubation poses high risk of transmission of severe acute respiratory syndrome coronavirus 2 and other respiratory pathogens. We designed and here describe a protective drape that we believe will greatly reduce this risk. Unlike the intubation box that has been described prior, it is portable, disposable, and does not restrict operator dexterity. We have used it extensively and successfully during the height of the corona virus disease of 2019 outbreak.
