New formula for selection of an appropriate left-sided double-lumen tube size in thoracic anaesthesiology

In thoracic anaesthesiology, double-lumen endobronchial tubes are used to provide one-lung ventilation. However, selecting the appropriate double-lumen endobronchial tube size to provide the most suitable ventilation with minimal damage is a challenging task for anaesthesiologists. There is no standardised approach to this issue. The present study aimed to develop a standardised mathematical formula for determining the appropriate size of the...
