Abstract

Objective: To introduce a new method to do safe bronchoscopy, a highly aerosol generating procedure through disposable COVID box in this difficult COVID time.

Methods: We have introduced an unbelievably cheap and effective method "DISPOSABLE COVID BOX". We took an acrylic board 70 × 20 cm and attached 3 bars 32 cm long and slide it under the side of the patient. A similar contraption is used on the other side. Then, it is covered by a polypropylene sheet 2' × 2'. It makes a completely disposable airtight chamber with the polypropylene sheet. We make a 1 cm nick in the sheet and introduce the video-bronchoscope, which is further navigated into the patient without any discomfort either to the patient or Bronchoscopist. When the procedure is finished, scope is withdrawn from the patient and the polypropylene sheet is squeezed out. The polypropylene sheet is removed and disposed off with all precautions, and the acrylic boards and the bars are cleaned with 1% Sodium hypochlorite solution. This way, the cost is only of polypropylene sheet which is negligible.

Results: Videobronchoscopies in indicated patients were done using this novel disposable covid box. This new invention called Disposable COVID box has been practiced for the first time, it's an innovative technique about which we want the world to be known.

Conclusion: To conclude, there are no aerosols released in atmosphere after the procedure, making it absolutely safe for bronchoscopist and at same time patient also remains safe. We are ready again in no time with fresh polypropylene sheet to do the next bronchoscopy.

Keywords: Acrylic board; Bronchoscopy; Disposable covid box; Polypropylene sheet; Sodium hypochlorite.
