BACKGROUND
Single-use flexible bronchoscopes have gained popularity in recent years for various advantages over the traditional reusable bronchoscope. There are several commercially available disposable bronchoscopes; however, all have limitations compared to reusable bronchoscopes. The Vathin H-SteriScope is a single-use flexible bronchoscope that may have overcome some of these limitations.
METHODS
We designed a survey to evaluate the performance of this new single-use bronchoscope on a bronchoscopy model with operators who are familiar with current single-use and reusable bronchoscopes. The operators were asked to rank overall assessment, scope quality, handling, maneuverability, tool interaction, and image quality of the H-SteriScope on a scale of 0-100. These operators were then asked to rank their current single-use and reusable bronchoscopes with the same scale. The results were evaluated to determine the operator perception of the H-SteriScope.
RESULTS
The H-SteriScope and current reusable bronchoscopes were perceived to have significant differences compared with currently available single-use bronchoscopes in overall assessment of the scope, scope quality, handling, maneuverability, tool interaction, and image quality ( < .001). The H-SteriScope was perceived to have similar maneuverability as the reusable bronchoscope ( = .86). There were no differences among the H-SteriScope ( = .88), the current single-use bronchoscope ( = .84), and the current reusable bronchoscope ( = .89) between the training and nontraining interventional pulmonology subgroups.
CONCLUSIONS
In terms of operator perception, the H-SteriScope appears to have similar maneuverability as the reusable bronchoscope. Both the H-SteriScope and the reusable bronchoscopes performed better in all measured sectors than the current single-use bronchoscope. Additional studies are required to evaluate the practicality, safety, and cost efficiency of the H-SteriScope in clinical practice.

BACKGROUND
Single-use flexible bronchoscopes eliminate cross contamination from reusable bronchoscopes and are cost-effective in a number of clinical settings. The present bench study aimed to compare the performance of a new single-use bronchoscope (Boston Scientific EXALT Model B) to a marketed single-use comparator (Ambu aScope 4), each in slim, regular and large diameters.
METHODS
Three bronchoscopy tasks were performed: water suction and visualization, "mucus" mass (synthetic mucoid mixture) suctioned in 30 s, and "mucus" plug (thicker mucoid mixture) suction. Suction ability, task completion times, and subjective ratings of visualization and overall performance on a scale of one to 10 (best) were compared. All bronchoscopy tasks were completed by 15 physicians representing diversity in specialization including pulmonary, interventional pulmonary, critical care, anesthesia, and thoracic surgery. Each physician utilized the six bronchoscope versions with block randomization by bronchoscope and task.
RESULTS
Aspirated mean mass of "mucus" using EXALT Model B Regular was comparable to that for an aScope 4 Large (41.8 ± 8.3 g vs. 41.5 ± 5.7 g respectively, p = 0.914). In comparisons of scopes with the same outer diameter, the aspirated mean mass by weight of water and "mucus" was significantly greater for EXALT Model B than for aScope 4 (p < 0.001 for all three diameters). Mean ratings for visualization attributes were significantly better for EXALT Model B compared to aScope 4 (p-value range 0.001-0.029).
CONCLUSION
A new single-use bronchoscope provided strong suction capability and visualization compared to same-diameter marketed single-use comparators in a bench model simulation.

Review
Bronchoscopy is a commonly performed procedure within thoracic and critical care medicine. Modern bronchoscopes are technologically advanced tools made of fragile electronic components. Their design is catered to allow maximum maneuverability within the semi-rigid tracheobronchial tree. Effective cleaning and reprocessing of these tools can be a challenge. Although highly functional, the design poses several challenges when it comes to reprocessing. It is a very important step, and lapses in the procedure have been tied to nosocomial infections. The process lacks universal standardization; several organizations have developed their own recommendations. Data have shown that key stakeholders are not fully versed in the essentials of endoscope reprocessing. A significant knowledge gap exists between those performing bronchoscopy and those who are stewards of effective endoscope reprocessing. To service as a resource for bronchoscopists, this study summarizes the steps of effective reprocessing, details the important elements within a health-care facility that houses this process, and reviews some of the current data regarding the use of disposable endoscopes.

Developing a magnetic POCUS-guided bronchoscope for patients with suspected difficult endotracheal intubation in a general tertiary hospital: protocol for a randomised controlled study.
INTRODUCTION
Endotracheal intubation (ETI) is a crucial but risky procedure, especially among patients suspected of difficult endotracheal intubation (DTI). Bronchoscope, as an improved technique commonly used in DTI, might encounter visualisation difficulties. The magnetic point-of-care ultrasound (MGPOCUS) provides a novel visualisation from the outside and enables estimation of the relative position and trajectory of the bronchoscope. The purpose of the study was to evaluate the efficiency of MGPOCUS-guided bronchoscopy, including the time required for successful ETI, the first attempt and overall success rate, the number of attempts, complications, and satisfaction with the visualization of the procedures.
METHODS AND ANALYSIS
The study is a randomised, parallel-group, single-blinded, single-centre study. Participants (n=108) will be recruited by the primary anaesthesiologist and randomised to groups of ETI with bronchoscope or MGPOCUS-guided bronchoscope. The primary outcome is the time taken to the first-attempt success ETI. Secondary outcomes include procedure time, the first-attempt and overall success, complications, and satisfaction of visualisation. Cox regression with Bonferroni correction and linear mixed regression will be used to analyse the outcomes.
ETHICS AND DISSEMINATION
The trial protocol was approved by the ethics committees at the Peking Union Medical College Hospital (Institutional Review Board #ZS-3428). Findings will be disseminated through conference presentations and peer-reviewed journals.

BACKGROUND
Flexible bronchoscopy can play an important role in the evaluation of an airway lumen during therapeutic bronchoscopic procedures. Despite its potential usefulness, however, evaluation with a standard-sized bronchoscope, which cannot pass completely through a severely stenosed airway, is often unsatisfactory.
OBJECTIVES
This study aimed to evaluate the usefulness of prototype thin bronchoscopes for assessing stenotic airways during stenting procedures.
METHODS
Forty-six patients with central airway stenosis requiring stent implantation were enrolled in this prospective study. After inserting a rigid bronchoscope under general anesthesia, a flexible bronchoscopic evaluation using a 5.9- or 6.0-mm standard bronchoscope was performed, followed by evaluation using a prototype 3.4- or 3.5-mm thin bronchoscope for airways beyond the site of stenosis, which could not be visualized by the standard bronchoscope.
RESULTS
A standard bronchoscope could not pass through the stenotic airway in 15 of 46 patients (33%). On univariate analysis, the grade of stenosis (p < 0.001), the presence or absence of atelectasis (p = 0.04) and the presence or absence of viscous secretions (p = 0.02) were related to the rate of successful passage by a standard bronchoscope. On multivariate analysis, only the grade of stenosis remained independently associated with the success rate. In 12 of the 15 patients (80%), the airway lumen beyond the stenotic lesion, which could not be reached by a standard bronchoscope, was successfully visualized and evaluated with a thin bronchoscope. No significant complications were associated with the procedures.
CONCLUSION
The thin bronchoscope can be a useful tool for evaluating a severely stenosed airway during the stenting procedure.
