In this step-by-step demonstration of the adapted fibreoptic intubation technique, the study used a manikin to represent the patient The patient is placed in the supine position on the operating table and draped with a surgical microscope drape (Zeiss MD Microscope Drape, 65 mm lens cover) The microscope drape is a clear plastic material that includes an annular housing, which is normally designed to fit around the objective lens portion of the microscope In this adapted technique, the annular housing is positioned around the mouth and nose of the patient The microscope drape further includes several sleeve cuffs, which normally serve as eyepiece covers for the surgical microscope Forearms of an assistant can be inserted through two small cuts in the sleeve cuffs to keep a tight fit The assistant will proceed with hands underneath the drape, allowing him to stabilise the scope with the hand over the nose or mouth if needed, advance the ETT into the trachea over the scope shaft, inflate the ETT cuff, and secure the ETT with a clamp just after fibreoptic shaft withdrawal The fibrescope with its cover are then securely removed in one-step;the tracheal tube is connected to the breathing circuit and the clamp is subsequently removed This technique, which uses accessible operating theatre supplies, can be a useful adjunct in minimising viral contamination by respiratory secretions during outbreaks of highly infectious diseases, such as COVID-19
