RESUMO
Objective: The purpose of this article is to introduce a novel imaging device and technique for percutaneous dilatational tracheostomy (PDT) and evaluate its clinical application. Methods: We have modified the bronchoscope to generate a novel imaging device. The handle of the bronchoscope was removed and replaced with added fixation pieces to secure the new device to the endotracheal tube. Nine mechanically ventilated patients admitted to the intensive care department of Shandong Public Health Clinical Center who underwent PDT between July 2023 and January 2024 have been treated with this novel imaging device. The number of medical staff members needed for the operation, number of needle interventions, operation time, arterial blood gas analysis, and intraoperative complications were observed. Results: Three medical staff were involved in the procedure: an operator, an assistant, and a nurse. The first attempted needle intervention was successful in all patients, and no serious complications such as major bleeding, pneumothorax, mediastinal emphysema, accidental extubation, desaturation, hypercarbia, respiratory acidosis, hemodynamic abnormality, or posterior tracheal puncture occurred. The average time was 11.63 ± 1.56 minutes from skin incision to the needle insertion and 4.43 ± 1.99 minutes from needle insertion to tracheal placement. Conclusions: PDT guided by the novel device is safe, preserves human resources, saves operating space, keeps the view stable, and makes the procedure easy. It is worthy of further research and application.
